North Carolina is one of the highest-demand ABA states in the country, and NC Medicaid covers ABA as "Research-Based Behavioral Health Treatment" (RB-BHT) under Clinical Coverage Policy 8F. The benefit is available in every delivery channel — NC Medicaid Direct, every Standard Plan, every Tailored Plan, and the new Children & Families Specialty Plan — and the plans must pay at least the state fee schedule. But 2025–2026 brought a rate cut and reversal, a major legislative overhaul (HB 696), and a rewritten Clinical Coverage Policy 8F that took effect August 1, 2026, so this is a market where staying current is part of the job.
RB-BHT is covered for members under 21 with an ASD diagnosis established using a scientifically validated diagnostic tool, via EPSDT — and, less well known, a State Plan Amendment effective July 1, 2021 extends RB-BHT coverage to adults 21 and older as well. For children under three, a provisional diagnosis is accepted at the time services begin, with a definitive diagnosis expected within six months — a detail worth capturing so young families aren't turned away prematurely.[34][35][36][12][20][21]
The benefit exists in every delivery channel: NC Medicaid Direct, the Standard Plans (Healthy Blue, AmeriHealth Caritas, Carolina Complete Health and UnitedHealthcare Community Plan — WellCare of North Carolina merged into Carolina Complete Health on April 1, 2026), the Tailored Plans (launched July 1, 2024 as Alliance, Trillium, Vaya and Partners; Vaya Health and Partners Health Management merged into Vaya Partners on October 1, 2026, so NCDHHS now lists three: Alliance Health, Trillium Health Resources and Vaya Partners), and the Children & Families Specialty Plan for child-welfare-involved members (launched December 1, 2025). The clinical rules are 8F everywhere; each plan's guide below covers its submission mechanics and quirks.[34][35][36][12][20][21]
Prior authorization is required for all RB-BHT services — including the assessment. Authorization length is tiered by intensity, which is the detail most often missed: CCP §5.1 gives up to 180 calendar days for treatment plans of 16 hours or fewer per week, but only up to 90 calendar days when the plan exceeds 16 hours a week — so most comprehensive programmes reauthorise quarterly, not twice a year. The reauth must be submitted before the current authorization expires. The treatment plan is developed by a Licensed Qualified Autism Service Provider (LQASP), and the 8/1/2026 rewrite replaced the old fixed review-and-annual-rewrite cycle (subsection 5.3.4 was retitled "Treatment Plan Reviews and Updates" and "Annual Rewriting" removed): the responsible professional must review the plan at each goal's target date or expiration — each goal reviewed separately, with short-range goals never exceeding 12 months from the date of the plan — and whenever the beneficiary's needs change, the service provider changes, or a new service is added. In practice the plan is also reviewed, modified and resubmitted at every reauthorization (every 180 days at ≤16 hrs/week, every 90 above). At least 10% of all services provided by a paraprofessional must involve observation and direction of that paraprofessional by an LQASP. As with any long review cadence, the baseline data collected at intake is what every future review is measured against.[12][2]
What a reauthorization must contain: CCP 8F §5.1.1 requires the treatment plan to be “reviewed, modified, and submitted for reauthorization” at least every 180 days (16 hours a week or fewer) or every 90 days (above 16), and before the current authorization expires. The decision rests on “the medical necessity documented in the Treatment Plan, the authorization request form, and supporting documentation.” The policy’s continued-stay criteria (§3.2.7) ask for documentation of progress toward the plan’s goals, or of the modifications made when progress has stalled. Every goal must carry “current baselines and measurement methods for each goal, including starting points, progress milestones and target dates, and intervals for frequency of measurement” (§5.3.3.3), and an adaptive behavior assessment must have been done within the last 3 years. CCP 8F does not say the data must be graphed; tables or graphs both meet the rule, as long as each goal shows its baseline and current measurement.[12][2]
Code set: RB-BHT bills only under the CPT codes in Attachment A, 97151–97157, in 15-minute units. 97158, 0362T and 0373T are not in the table. No HCPCS H-code is an RB-BHT code: H0031 appears in NC Medicaid’s health-plan billing guidance only as a general behavioral health assessment code, and nothing in 8F lets H0031, H0032, H2014 or H2019 be billed for ABA. 96112 (developmental test administration) is not an RB-BHT code either. The billing guidance lists it among the procedure codes shared by physical and behavioral health, so it bills as developmental testing, outside 8F and its RB-BHT authorization.[12][2]
NC Medicaid publishes RB-BHT rates, and every plan — Standard, Tailored, or LME/MCO — must reimburse at no less than 100% of the state fee schedule unless the provider agrees otherwise, which makes the schedule an effective statewide floor. Current per-15-minute rates (effective 10/1/2025): 97151 $30.56, 97152 $61.73, 97153 $20.81, 97154 $11.37, 97155 $32.22, 97156 $23.70, 97157 $11.51. Know the recent history too: a 10% RB-BHT cut took effect October 1, 2025 during a budget shortfall, was reversed by the Governor's December 10, 2025 directive, and restored schedules posted January 5, 2026 — so any rate sheet dated fall 2025 is wrong in your favor.[9][8][22]
Are the NC Medicaid plans open or closed to new ABA providers? For RB-BHT the statutory answer changed this summer. Section 9E.22 of the 2026 Current Operations Appropriations Act (S.L. 2026-41, approved July 7, 2026 and effective when it became law) added a "Mandatory Closed Networks" subsection to G.S. 108D-22: "Each PHP shall develop and maintain a closed network, and may exclude providers from that closed network" for peer support services and research-based behavioral health treatment services. "PHP" in Chapter 108D covers both the Standard Plans and an LME/MCO under a capitated contract (the Tailored Plans), and the same section extends the rule to the Children and Families Specialty Plan. Before that, Standard Plans had to run open networks — excluding a provider only for failing objective quality standards or refusing network rates — and S.L. 2026-1 (HB 696) had only allowed a plan to close a designated service category with Department approval.[37][38][39][40][13][41][24][25][26][27]
What this means at intake and in contracting: a plan may now decline to contract with a new RB-BHT provider, so being enrolled in NCTracks no longer guarantees a network agreement, and a family's choice of provider is bounded by who each plan has contracted. No public NC Medicaid guidance on how plans are applying the closed network was found — the July 21, August 5 and August 31, 2026 RB-BHT bulletins do not mention it, the codified G.S. 108D-22 on ncleg.gov did not yet show the new subsection when checked on September 27, 2026, and Trillium's provider manual (effective July 20, 2026) still describes an open network. Whether a given plan is accepting new RB-BHT providers today is a per-plan question for its contracting team.[37][38][39][40][13][41][24][25][26][27]
What the plans themselves have published (checked October 1, 2026): Trillium's Provider Communication 005 (July 9, 2026) says that "Trillium will be maintaining a closed network" for RB-BHT and peer support, which supersedes its manual's open-network language for these services. Vaya Health (bulletin of July 8, 2026) and Partners Health Management (provider alert of July 8, 2026) use the same wording: only contracted providers within the approved closed network may deliver RB-BHT, current providers "should continue operating as contracted and approved," and each plan "will evaluate new requests to provide RB-BHT and PSS on a case-by-case basis against our selection criteria, which includes a network need." Alliance Health lists RB-BHT among its mandatory closed-network services and says providers interested in delivering them "must go through Alliance's specific contracting and credentialing processes"; they are "not available through our standard network participation agreements." No equivalent notice was found from the four Standard Plans (AmeriHealth Caritas, Carolina Complete Health, Healthy Blue, UnitedHealthcare Community Plan), which are bound by the same statute.[37][38][39][40][13][41][24][25][26][27]
HB 696 (Session Law 2026-1, signed April 30, 2026) rewired NC Medicaid ABA, and the Clinical Coverage Policy 8F rewrite it directed has now been finalized and published, effective August 1, 2026 (Amended Date: August 1, 2026) — confirmed directly from NC Medicaid's live 8F policy page, corroborated by NC Medicaid's August 31, 2026 bulletin restating the new requirements for providers. The codified rules: assessments must be in-person (telehealth assessments aren't reimbursed absent a documented exception); telehealth is removed entirely — no documented-necessity exception remains — for the three paraprofessional-delivered codes 97152, 97153, and 97154; 97151 keeps telehealth eligibility with clinical justification; 97155 keeps telehealth but capped at a maximum of 50% of total 97155 billing per beneficiary per 180-calendar-day period; 97156/97157 keep their own separate telephonic/KX caregiver-access-barrier exception, unchanged; the 10% LQASP observation floor is codified; paraprofessionals must hold RBT or ABAT certification within 120 calendar days, and that grace-period clock started on August 1, 2026 for staff already employed but not yet certified, not just new hires — after the window, claims for non-certified paraprofessionals aren't reimbursed; no new out-of-state BCBA/QASP-supervisor enrollments, and effective August 2, 2026 all LQASPs/C-QPs must enroll as in-state providers; and plans above 16 hours/week move to a 90-day initial-and-reauthorization cadence (plans at or under 16 hours/week keep the existing 180-day cadence) — a step down from the monthly-reapproval-softened-to-quarterly compromise in the budget signed July 7, 2026. NC Medicaid's transition guidance is explicit that existing prior authorizations aren't affected: providers don't need to take any action on existing authorizations, and no action will be taken to reduce an existing PA's duration — the new 90-day cadence binds only future reauthorizations. One correction to flag: NC Health News reporting (7/15/2026, quoting DHHS) had described the telehealth LQASP supervision cap as 20%; the finalized policy sets it at 50%, not 20% — treat the 20% figure as superseded. That same reporting's ~40-mile-radius detail on the out-of-state supervisor restriction still isn't confirmed in the finalized policy text available to us, so continue to treat it as reported, not codified.[10][12][13][11][23]
Start with the technician layer, because S.L. 2026-1 changed it: behavior technicians must be certified — RBT (BACB) or ABAT (QABA) — within 120 calendar days of their date of hire (or the agency's first Medicaid enrollment, whichever is later). The finalized CCP 8F, effective August 1, 2026, adds a specific wrinkle for the existing workforce: that same 120-day grace-period clock started running on August 1, 2026 for paraprofessional staff already on payroll but not yet certified, not only for new hires. New hires and existing staff alike may render services during the window under all required supervision, but the finalized policy is blunt about the consequence once the window closes: claims for non-certified paraprofessionals are not reimbursed. The BACB's own 2026 requirements have to fit inside that clock: a 40-hour training that must span at least 5 days, an initial competency assessment, an employer-run criminal background check plus a separate abuse-registry check completed within 180 days before the application (both reviewed by a BCBA-level Attesting Certificant who signs the attestation form), and the Pearson VUE exam — so start the packet on day one of employment, not day sixty.[12][13][14][15][16][17][18][19]
NC then stacks two state statutes on the BACB layer. G.S. 122C-80 requires a criminal history check for unlicensed hires at MH/DD/SA providers: a state check for applicants who've lived in NC five-plus years, state plus national fingerprint-based check for more recent arrivals, with the check request submitted within five business days of the conditional offer (conditional employment pending results is allowed, and a relevant conviction is weighed for seriousness, recency, and nexus to the job — not automatically disqualifying). Separately, G.S. 131E-256 requires checking the Health Care Personnel Registry BEFORE hiring any unlicensed staff with direct access — community-based DD service providers are covered even without a 122C license — and each registry access must be noted in your business files. The fourth layer is agency-level: NCTracks screens the enrolling organization and its 5%+ owners under the federal risk-based rules (42 CFR Part 455), with fingerprint-based checks for high-risk categories — confirm your agency's current risk category with NCTracks provider enrollment, and note that managed-care contracting never substitutes for NCTracks enrollment.[12][13][14][15][16][17][18][19]
Supervisors need an NC license, not just a certification: behavior analysts license through the NC Behavior Analyst Licensure Board (G.S. Chapter 90, Article 43) — LBA (current BCBA or QBA) at a $250 application fee, LaBA (BCaBA or QASP-S) at $200, each plus a $14 criminal-background-check fee run through Castle Branch (package VN90) and a completed fingerprint record card, submitted via the board's Licensure Gateway portal. Direct Medicaid enrollment as a BCBA requires both the certification and the license (taxonomy 103K00000X). The S.L. 2026-1 supervision floors are now codified in the finalized CCP 8F (effective 8/1/2026): at least 10% of all paraprofessional-delivered services must involve LQASP observation and direction; for beneficiaries above 200 paraprofessional hours per 180-day period, LQASP hours must land between 10% and 20% of paraprofessional hours, documented in the treatment plan with deviations clinically justified; telehealth on 97155 is capped at a maximum of 50% of total 97155 billing per beneficiary per 180-calendar-day period; telehealth is removed entirely (no exception) for 97152, 97153, and 97154; and out-of-state BCBAs can no longer newly enroll — effective August 2, 2026, all LQASPs/C-QPs must enroll as in-state providers. Plan-level certification adds essentially nothing on top — Alliance's RB-BHT guidance and WellCare's WNC.CP.109 both defer to the state baseline — the plans' real staffing exposure is agency certification reviews against DMH/DD/SAS standards and 10A NCAC 27G personnel files (job descriptions, supervision plans), not extra background checks.[12][13][14][15][16][17][18][19]
What happens when a family changes ABA providers? CCP 8F does not say that an existing authorization moves to a new agency. What it does set out: one of its transition-or-discharge criteria is that "the beneficiary and the treatment team determine that a different RB-BHT provider agency is needed to attain the goals as identified in the Treatment Plan," and when a family moves out of the area the current provider is expected to have "facilitated the referral to either a new RB-BHT provider or other appropriate service" and "assisted the beneficiary in the transition process." The Treatment Plan must be reviewed on a "change in service provider," and prior approval is "based on review of a beneficiary's Treatment Plan at the time of authorization request" — services delivered without prior authorization are not paid.[12]
Two other rules shape the handoff. Medicaid does not cover a service that "duplicates another provider's procedure, product, or service," so two agencies cannot bill the same RB-BHT service for the same period. Within an agency, "staffing changes require the individual responsible to consent to treatment for the beneficiary," and the Treatment Plan must name the providers responsible for delivery. Ask the family's health plan UM team whether the incoming agency needs a new prior approval (expect to submit its own Treatment Plan) and an end date on the outgoing agency's authorization.[12]
North Carolina licenses the practice itself: “it shall be a violation of this Article for any individual not licensed under this Article to practice behavior analysis” (G.S. 90-746(a); a Class 2 misdemeanor under 90-746(b)), with exemptions for NC-licensed psychologists and for behavior technicians working under a licensed professional’s direction (G.S. 90-745). An analyst licensed elsewhere has two routes: a temporary license for one who “resides and practices behavior analysis in another state,” available “only if the behavior analysis services are to be delivered during a limited and defined period of service approved by the Board” (G.S. 90-740), and licensure by reciprocity for someone actively licensed in a state with comparable requirements that reciprocates with North Carolina (G.S. 90-741). Article 43 contains no telehealth exception, so plan on an NC license before treating a child located in North Carolina by video.[28][29][13]
For NC Medicaid the answer is now no for a new enrollee. Session Law 2026-1 added G.S. 108C-9(e): “Board Certified Behavior Analysts and Qualified Autism Services Practitioner Supervisors shall not be permitted to enroll in the North Carolina Medicaid program as out-of-state providers,” applying to enrollment applications submitted on or after the law took effect. NC Medicaid’s August 31, 2026 reminder restates it: all LQASPs and C-QPs, “including Board Certified Behavior Analysts and Board Certified Assistant Behavior Analysts, seeking to enroll in the NC Medicaid program must do so as an in-state provider,” effective August 2, 2026.[28][29][13]
Only when Medicaid eligibility itself is retroactive. CCP 8F (amended 8/1/2026) says the provider “shall obtain prior approval before rendering Research-Based Behavioral Health Treatment services,” and “Services provided without prior authorization are not considered for payment or reimbursement except in the case of retroactive Medicaid eligibility.” A beneficiary who becomes retroactively eligible while receiving covered services is entitled to be reimbursed by the provider for money paid during the retroactive period (other than third-party payments or cost-sharing), and “The qualified provider may file for reimbursement with Medicaid for these services” (10A NCAC 22J.0106). Everything else, including the 97151 assessment, needs approval first.[12]
NC Medicaid sets the claim clock for every plan that pays RB-BHT. Its prompt-payment fact sheet gives Standard Plans a 365-day timely filing window (since July 1, 2023) and Tailored Plans the same 365 days (since July 1, 2024). For NC Medicaid Direct, the LME/MCO window moved from 90 to 365 days on July 1, 2024. The window covers the original claim and any corrected claim. State-funded services stay at 90 calendar days.[30][31][4][3][2][1]
Plans must tell the provider within 18 calendar days whether a medical claim is clean or pend it for information. They must pay or deny a clean claim within 30 days, deny the claim if requested information has not arrived within 90 days, and pay 18% annual interest on late payments.[30][31][4][3][2][1]
Electronic Visit Verification is not an RB-BHT requirement. NC Medicaid’s EVV page says the Cures Act requires EVV for Personal Care Services and Home Health Care Services, and lists PCS, CAP/C, CAP/DA, Home Health and the Innovations and TBI waivers as the services that use it. RB-BHT is not on that list.[30][31][4][3][2][1]
NC Medicaid Direct claims go through NCTracks, which must receive them “within 365 days of the first date of service.” Payment is weekly: “NC Medicaid has checkwrites 50 weeks of the calendar year – no checkwrites occur the week of June 30 and the week of Christmas.” Claims are processed in real time, and the submission cutoff for each checkwrite is printed on the NCTracks checkwrite schedule (Quick Links on the NCTracks provider portal). In 2026 the last checkwrite of the state fiscal year was June 23 and the next was July 7. Payment is by EFT only; claims for a provider without valid EFT details suspend for 45 days and then deny.[30][31][4][3][2][1]
Taxonomy: every health plan must “validate the taxonomy code submitted on the claim” against the provider’s NC Medicaid enrollment record and “price claims based on the taxonomy code submitted on the claim” (billing guidance §3.22), so bill the taxonomy you are enrolled under in NCTracks.[30][31][4][3][2][1]
Referring or ordering NPI: not required on an RB-BHT claim. NC Medicaid’s OPR guidance lists the claim types that need an ordering NPI (home infusion, private duty nursing, labs, IDTF, CAP, radiology, DME, LEA) or a referring NPI (home infusion, specialized therapy, hospice, home health, PDN, dialysis, CAP, LEA), and RB-BHT is not on either list. The physician or psychologist who signs the service order must still be enrolled in NC Medicaid (42 CFR 455.410).[30][31][4][3][2][1]
The questions that decide whether a family can start with North Carolina Medicaid, and what they have to bring. Each maps onto something intake should ask on the first call.
No upper age bound in the policy. The 8/1/2026 rewrite struck the phrase "under 21 years of age" from the eligibility provision at subsection 2.1.2, and a 2021 State Plan Amendment extends RB-BHT to adults 21 and older. Under-21 beneficiaries additionally carry the EPSDT special provision (42 U.S.C. § 1396d(r)), under which limits on scope, amount, duration, frequency and location of service may be exceeded where documentation shows the service is medically necessary to correct or ameliorate the condition. At the bottom end, beneficiaries under three years of age at the time services begin may start on a provisional diagnosis.[12]
CCP 8F sets no expiry date on the ASD diagnosis itself — medical necessity requires a "current ASD diagnosis" recognised by the current edition of the DSM. Two clocks do run. A beneficiary who started under age three on a provisional diagnosis must have a non-provisional ASD diagnosis within six months of the provisional one, or the provider implements transition or discharge. And at least one adaptive behavior assessment must have been completed within the last 3 years. The provider must verify and hold documentation of a qualifying ASD diagnosis before initiating RB-BHT; services rendered without adequate diagnostic documentation are subject to denial, recoupment or termination.[12]
Non-provisional ASD diagnosis: a Licensed Psychologist (where an autism diagnosis is within their experience and competence under Article 18G of the Psychology Practice Act), a Licensed Psychological Associate with the required supervision, or a physician (MD or DO) acting within their legal NC scope. An evaluation by a Licensed School Psychologist that includes any or all of the required testing may be used to meet the diagnostic criteria where there is no clinical indication to repeat testing. A provisional diagnosis for an under-3 may additionally be made by a licensed clinician with at least a master’s degree who has completed the training and supervision to administer validated ASD instruments and for whom this is within scope.[12]
The non-provisional ASD diagnosis must be made with one of four named instruments (or later versions): Brief Observation of Symptoms of Autism (BOSA), Tele-ASD-Peds (TAP), ADOS-2, or CARS2-ST / CARS2-HF. Services may not be initiated on screening tools, educational determinations or informal clinical impressions alone. The authorization packet also needs a skills assessment using VB-MAPP, ABLLS-R or the ESDM Curriculum Checklist, a functional behavior assessment (or functional behavioral analysis at provider option) where challenging behaviors are targeted, and an adaptive behavior assessment completed within the last 3 years — VABS-3, ABAS-3 or DP-4. An alternative instrument may be substituted with clinical justification where the required one is not clinically indicated.[12]
Yes — a written service order completed and signed by a Licensed MD, Licensed DO or Licensed Psychologist working within scope, signed and dated with the date the service was ordered. It must be in place prior to or on the day the service is first provided, must rest on a behavioral, adaptive or functional assessment plus a treatment plan built from that assessment, and is valid for one year: medical necessity must be reconfirmed and services re-ordered annually from the date of the original order. 97151 and 97152 do not require a service order or treatment plan for prior approval; a service order must be in place before 97153, 97154, 97155, 97156 or 97157.[12]
Per code, under Attachment A of the 8/1/2026 policy. Telehealth billable with modifier GT: 97151, with clinical justification recorded in the treatment plan; and 97155, capped at a maximum of 50% of total 97155 billing per beneficiary per 180-calendar-day period, with clinical justification in the treatment plan if more telehealth units are needed. Not telehealth billable at all: 97152, 97153 and 97154. 97156 and 97157 are telehealth eligible and are additionally the only telephonic (audio-only, modifier KX) services, allowed where the caregiver’s physical or behavioral health status, or an access barrier such as transportation or technology, prevents in-person or telehealth participation. Telehealth and telephonic claims are filed with the provider’s usual place-of-service code, and delivery follows Clinical Coverage Policy 1-H. Supervision by video is allowed within that 97155 cap: observation for modification of intervention and technician direction may be given with the observing provider "in the same room or observing via telehealth" while the paraprofessional delivers in-person treatment. For 97151, what the policy asks for is clinical justification in the beneficiary’s Treatment Plan (the plan must include, if applicable, clinical justification for use of telehealth or telephone); CCP 8F does not separately require the telehealth modality to be named in the prior approval, and 97151 and 97152 need neither a service order nor a Treatment Plan for prior approval. The statute behind the rewrite is stricter on assessments: S.L. 2026-1 §3C.18(a)(5), as amended by S.L. 2026-41, says patient assessments are required to be conducted in person and assessments conducted via telehealth shall not be reimbursed unless exceptions are developed. So document the justification in the plan and ask the plan’s UM whether it wants the modality on the request. NC Medicaid’s bulletin adds that beneficiaries are not required to use telehealth and must be allowed in-person services on request. The state’s billing guidance to its health plans turns this into a claim edit: “CPT codes 97152–97154 can only be billed for services provided in person,” and “Claims submitted with Modifier GT (Telehealth) for 97152 - 97154 are not reimbursable and should be denied” (v36 §3.54.1).[12][37][13][2]
NC Medicaid Direct (fee-for-service): the state’s prior-approval page says Medicaid "will make every effort possible to make a decision within 15 business days of receipt of the request unless there is a more stringent requirement" — and a more stringent one now exists: since January 1, 2026, 42 CFR 440.230(e) requires state fee-for-service decisions within 7 calendar days for a standard request (extendable up to 14 calendar days when more information is needed) and 72 hours for an expedited one. Health plans (Standard, Tailored, CFSP): the federal managed-care ceiling is 7 calendar days standard for rating periods starting on or after January 1, 2026 — NC’s rating period starts July 1, so from July 1, 2026 — plus up to 14 extension days, and 72 hours expedited; the posted Standard Plan contract text still reads "no later than fourteen (14) calendar days following receipt of the request", and plan manuals vary (see each plan). Reauthorization: CCP 8F says "Reauthorization must be submitted prior to initial or concurrent authorization expiring" (every 180 days at ≤16 hrs/week, every 90 above), and NC Medicaid asks providers to "request authorization of a continuing services 10 calendar days before the end of the current authorization period" so services continue during any adverse-decision notice period.[42][43][44][45][46][12]
Medicaid pays last. "Medicaid is the 'payer of last resort' by federal law" — Medicare and private carriers "must process a claim before Medicaid processes a claim." CCP 8F restates it for RB-BHT: providers "shall bill all other third-party payers, including Medicare, before submitting a claim for Medicaid reimbursement." Ask about other coverage before the first session; where it shows on the NCTracks record "the provider must bill the carrier before billing Medicaid" and must hold the primary carrier’s EOB with the payment or denial, then file with Medicaid within 180 days of that EOB date. A denial the provider caused with the other plan cannot be overridden at Medicaid — fix it with that carrier. Prior approval still applies: CCP 8F requires prior approval before rendering RB-BHT and makes no exception for members with other insurance. Pay-and-chase: health plans pay first and recover for EPSDT and, per the state’s plan billing guidance, "If a prior authorization is approved as EPSDT medical necessity, health plans should pay and chase for all claims related to this prior authorization"; RB-BHT codes are not on the TPL bypass list. Federal program order: TRICARE pays after all other health insurance except Medicaid (so TRICARE pays before Medicaid), and CHAMPVA pays first when the member is also Medicaid-eligible.[47][12][2][48][49][50]
Coverage decides whether North Carolina Medicaid pays. These decide whether the claim survives: how sessions must be staffed and supervised, what may be billed concurrently, the per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.
At least ten percent of all services delivered by a paraprofessional must involve observation and direction of that paraprofessional by a Licensed Qualified Autism Service Provider (LQASP). For a beneficiary receiving more than 200 hours of paraprofessional-delivered RB-BHT in a 180-calendar-day period, the ratio of LQASP-delivered to paraprofessional-delivered hours must be no less than 1:10 (10%) and no more than 2:10 (20%), measured over the authorization period and documented in the treatment plan; any plan requesting a ratio outside that band needs written clinical justification. Incidental supervision — ensuring competent, ethical practice, adherence to employer policy, ongoing skill development and personal support — is not billable. CCP 8F sets no caseload cap: nothing in the policy limits how many paraprofessionals one LQASP may supervise. The binding numbers are the 10% observation floor and the 10–20% hours band per beneficiary.[12]
Yes, in one direction only. 97153 and 97154 may be billed concurrently with 97155 when the paraprofessional is delivering the direct service and an eligible provider is observing; 97155 may be billed concurrently with 97153 or 97154. A single rendering provider may not bill 97153 or 97154 and 97155 simultaneously. 97151, 97152, 97156 and 97157 carry no concurrent-billing allowance. Separately, a non-RB-BHT Medicaid service may not be billed at the same time as an RB-BHT service, though same-day delivery is allowable. ABA alongside speech, occupational or physical therapy: Policy 8F (amended 8/1/2026) §4.2.1(n) does not cover "non-RB-BHT Medicaid services billed at the same time as RB-BHT service (as reflected in the session note …). Same-day delivery is allowable." So a speech, OT or PT visit may fall on the same day as ABA, but not on the same clock time as a billed RB-BHT session — and the session note, which must record session time in and out (§5.5.1), is what shows the two did not overlap. §4.1(c) separately excludes any service that duplicates another provider's service.[12]
Two different ceilings. Per day, a claim edit: NC Medicaid applies the CMS Medicaid National Correct Coding Initiative to professional claims, including Medically Unlikely Edits — units-of-service edits that define for each CPT or HCPCS code "the number of units of service that is unlikely to be correct" — and its billing guidance tells every health plan to apply NCCI and MUE edits as well (§3.6.2). The public CMS Medicaid NCCI practitioner MUE table for dates of service 10/1–12/31/2026 sets these maxima per beneficiary per date of service: 97151 32 units, 97152 16, 97153 32 (8 hours), 97154 18, 97155 24, 97156 16, 97157 16, 97158 16, 0362T 16 and 0373T 32. Units above the MUE on one date of service deny as a claim edit whatever the authorization allows; the authorization, not the MUE, is the real weekly limit. Per authorization period: CCP 8F itself publishes no per-day unit ceiling — every RB-BHT code bills in 15-minute units and Attachment A carries no daily maximum. The binding limits are per authorization period: treatment plans at 16 hours per week or fewer get up to 180 calendar days initial and reauthorize at least every 180 days, while plans above 16 hours per week get up to 90 calendar days and must be reviewed, modified and resubmitted at least every 90 days. Within a 180-day period, 97155 telehealth is capped at 50% of total 97155 billing, the LQASP-to-paraprofessional ratio band is 10–20% once paraprofessional hours pass 200, and a minimum of six caregiver training sessions must be completed. Hours spent in educational settings and receiving IEP services are excluded from the treatment-hour calculation.[12][6][2][5]
The staff member who provides the service signs the written entry, and the signature documents credentials for a professional or a job title for a paraprofessional. Notably, an LQASP or Certified Qualified Professional is NOT required to countersign a service note written by staff who hold neither status. A full service note is required for each contact or intervention on each date of service, carrying beneficiary name, Medicaid ID, date, service name, type of contact, place of service, purpose against a treatment-plan goal, description of the intervention, duration with session time in and out, assessment of effectiveness with data collected, caregivers present, a plan-of-care or protocol modification note for 97155, and the signature, date and credentials or job title of the staff member — with the beneficiary name, Medicaid ID and record number on every page. The treatment plan itself must be signed and dated by the responsible LQASP and the person consenting to treatment before services are delivered.[12]
Clinic, office, home, school and community settings are all payable, in any combination across the course of treatment, with the place-of-service decision documented in the treatment plan, made individually in collaboration with the family, and clinically justified for each location; where treatment starts in a structured clinic setting the goal is to advance into the beneficiary’s natural settings. Team members may not appear at a beneficiary’s place of work without prior permission. Services available through IDEA or other educational programs that duplicate or supplant the authorized treatment plan are not covered, nor is 1:1 support that substitutes for educational personnel. Telehealth and telephonic claims are filed with the provider’s usual place-of-service code.[12]
A professional claim (CMS-1500 / 837P) billed through the beneficiary’s health plan or its dedicated vendor. Attachment B fixes who may render each code: 97151 by a physician, Licensed Psychologist / Licensed Psychological Associate or Licensed Behavior Analyst; 97152, 97153 and 97154 by a behavior technician under the direction of one of those practitioners or an LaBA, or by the practitioner directly; 97155 by a physician, psychologist, LBA or LaBA (non-licensed analysts only under required supervision); 97156 and 97157 by a physician, psychologist or LBA. Behavior technicians must be certified as an RBT (BACB) or ABAT (QABA) and produce evidence to the agency within 120 calendar days of hire or of the agency’s first Medicaid enrollment, whichever is later, and must stop rendering if they miss that window. The agency must be enrolled with NC Medicaid through NCTracks, and per NC Medicaid’s August 2026 reminder all LQASPs and C-QPs must enroll as in-state providers as of August 2, 2026.[12][13]
No. RB-BHT is billed only with CPT 97151–97157 under CCP 8F Attachment A. H-codes such as H0031 belong to other behavioral health services, and 97158, 0362T and 0373T are not covered either.
Not by name. CCP 8F requires a reviewed and modified treatment plan with current baselines, measurement methods, progress milestones and target dates for each goal, plus documentation that supports continued medical necessity. Graphs are a common way to show that, but the policy does not require them.
Yes — as Research-Based Behavioral Health Treatment (RB-BHT) under Clinical Coverage Policy 8F, in every delivery channel (Medicaid Direct, Standard Plans, Tailored Plans, and the Children & Families Specialty Plan). All RB-BHT services require prior authorization, including the assessment.
Published per-15-minute rates, effective 10/1/2025: 97151 $30.56, 97153 $20.81, 97155 $32.22, 97156 $23.70 — and every managed-care plan must pay at least 100% of the state fee schedule unless the provider agrees otherwise.
In-person assessments (telehealth assessments aren't reimbursed absent a documented exception); no new out-of-state BCBA/LQASP/C-QP supervisor enrollments, with all LQASPs/C-QPs required to enroll as in-state providers by August 2, 2026; RBT/ABAT certification for paraprofessionals, with a 120-day grace period that started August 1, 2026 for existing uncertified staff as well as new hires (claims for non-certified paraprofessionals aren't reimbursed after the window); telehealth removed entirely for 97152, 97153, and 97154; a 50% cap on telehealth for 97155 (per beneficiary, per 180-calendar-day period — not the 20% some earlier reporting described); a codified 10% LQASP observation floor; and a move to 90-day initial-and-reauthorization periods for plans above 16 hours/week. These provisions are codified in the rewritten Clinical Coverage Policy 8F, effective August 1, 2026. Existing prior authorizations aren't affected — no action is needed and no existing PA's duration will be reduced.
For children under three, NC Medicaid accepts a provisional ASD diagnosis when services begin, with a definitive diagnosis expected within six months.
Partly, code by code under CCP 8F (eff. 8/1/2026): 97151 with clinical justification in the treatment plan; 97155 up to 50% of total 97155 billing per beneficiary per 180 days; 97156/97157 by telehealth, and by telephone (KX) only for a documented caregiver health or access barrier. 97152, 97153 and 97154 cannot be billed by telehealth at all. Claims carry modifier GT and the usual place-of-service code.
CCP 8F asks for clinical justification in the treatment plan; it does not separately require the modality to be approved in the prior approval, and 97151/97152 need no service order or treatment plan for prior approval. But the underlying statute (S.L. 2026-1 §3C.18, as amended) says assessments are to be in person and telehealth assessments are not reimbursed unless exceptions are developed, so justify it in the plan and ask the member's plan UM whether it wants telehealth flagged on the request.
Yes, for 97155 (protocol modification / observation and direction), capped at 50% of total 97155 billing per beneficiary per 180-calendar-day period, with clinical justification in the treatment plan to go higher. The observing LQASP may be in the room or observing via telehealth while the technician delivers 97153 in person. Incidental supervision is not billable.
Closed by statute for RB-BHT since July 7, 2026: S.L. 2026-41 §9E.22 requires every health plan (Standard Plans, Tailored Plans and the Children and Families Specialty Plan) to maintain a closed RB-BHT network, and lets it exclude providers. NC Medicaid has published no guidance on how plans are applying it. Trillium, Vaya, Partners and Alliance have each confirmed a closed RB-BHT network: current contracted providers continue, and Vaya and Partners review new requests case by case against network need. The Standard Plans have published nothing yet, so ask each plan's contracting team whether it is accepting new RB-BHT providers.
CCP 8F does not say an authorization transfers. It treats "a different RB-BHT provider agency is needed" as a transition or discharge reason, requires the Treatment Plan to be reviewed on a change in service provider, and bases prior approval on the Treatment Plan submitted with the request. It also bars paying two providers for duplicate services. Ask the family's health plan whether the new agency needs its own prior approval before its first session.
Yes, school is one of the payable settings, chosen with the family and clinically justified in the Treatment Plan. CCP 8F excludes services available through IDEA or other educational programs that duplicate or supplant the authorized Treatment Plan, teaching academic subjects, and acting as a substitute for a teacher, aide or tutor.
North Carolina requires an NC license to practice behavior analysis (G.S. 90-746), with no telehealth exception; temporary and reciprocity licenses exist (G.S. 90-740, 90-741). NC Medicaid no longer enrolls BCBAs as out-of-state providers (G.S. 108C-9(e), from S.L. 2026-1).
Only for retroactive Medicaid eligibility. CCP 8F: services without prior authorization “are not considered for payment or reimbursement except in the case of retroactive Medicaid eligibility.” Get approval before the first session, including 97151.
365 days from the date of service for Standard Plans (since 7/1/2023), for Tailored Plans and for NC Medicaid Direct claims the LME/MCOs process (both since 7/1/2024). The window covers corrected claims too. State-funded services are 90 days. Plans must pay or deny a clean claim within 30 days.
No. NC Medicaid applies EVV to Personal Care Services, Home Health, CAP/C, CAP/DA and the Innovations and TBI waivers. RB-BHT is not on its list.
