Oklahoma writes its ABA policy in unusual detail, and the detail is operational. OHCA publishes a dedicated rule set at OAC 317:30-5-310 through 317:30-5-318 (the core sections revised September 1, 2025) that names who may bill, who may diagnose, what medical necessity means, what an authorization packet must contain, what is excluded outright, what an extension must prove, how services are paid, and how OHCA audits them. Four of those rules should change how a practice runs Oklahoma intake. Only four CPT codes are reimbursable. The diagnostic evaluation behind the first request should be no more than two years old. Extensions may only be filed in the seven days before the current authorization ends, and late ones draw a technical denial with lost days. And parent training is a condition of continued hours: documented involvement below two hours a month "will result in a reduction of hours and possibly denial of services."
Since April 1, 2024 most children receive this benefit through a SoonerSelect health plan (Aetna Better Health of Oklahoma, Humana Healthy Horizons, or Oklahoma Complete Health), and OHCA says those plans "cover all services that SoonerCare fee-for-service covers." ABA is not carved out of managed care. But the plans are not the whole picture for autistic children: members eligible on the basis of disability (ABD) and anyone on a 1915(c) waiver are excluded from SoonerSelect and stay in traditional fee-for-service SoonerCare, where OHCA or its designated agent authorizes ABA directly.
OHCA's ABA provider page states plainly that "the CPT codes 97151, 97153, 97155 and 97156 will be utilized for reimbursement once the provider has a contract with OHCA." There is no 97152 technician-assessment line, no 97154 or 97158 group code, and no 0362T or 0373T. The July 1, 2026 SoonerCare fee schedule prices exactly those four: 97153 at $17.35 per 15-minute unit and 97151, 97155 and 97156 at $23.55 per unit, as maximum allowable fees. OHCA pays the lower of billed charges or that maximum, for direct service time only; pre- and post-session work, treatment planning, note writing and chart updates are not separately reimbursed (other than inside the FBA code).[14][15][2][7]
Contracting is its own gate. Every provider type must be "fully contracted with SoonerCare," "All staff providing ABA services must be contracted with the OHCA," and contracted providers must reside in Oklahoma or within 50 miles of the border. Enrollment runs through the OHCA provider portal under the Applied Behavior Analyst provider type (BCBA or BCaBA specialty), with the national certification and the state license or certificate uploaded, and a separate contract is required even for a provider already contracted for other SoonerCare services. Payment then goes up the chain: the rule says "Payment is not made to under supervision ABA practitioners/paraprofessionals, including but not limited to, BCaBAs and RBTs," and OHCA's provider page adds that payment for a supervised practitioner "may only be made to his or her supervisor, or the employing agency or corporate entity." The RBT "works under the license number of a BCBA."[14][15][2][7]
OAC 317:30-5-313 requires every condition together. The member is under twenty-one with "a definitive diagnosis of an Autism Spectrum Disorder (ASD)" from a pediatric neurologist or neurologist, a developmental pediatrician, a licensed psychologist, a psychiatrist or neuropsychiatrist, another licensed physician experienced in ASD, or an interdisciplinary team of a licensed psychologist, physician, physician assistant or APRN — practising in Oklahoma or within 50 miles of the border. The comprehensive diagnostic evaluation must carry a full medical and social history and rest on DSM criteria, "and/or may also include scores" from tools such as the ADI-R, ADOS-2 or CARS; "Screening scales are not sufficient." It is needed only at first initiation of ABA and "should be no older than two (2) years old," with no annual re-evaluation, though a member who changes agencies must supply it again during the initial authorization period. The child must also be medically stable, show functional limitations tied to ASD core deficits, and have shown atypical or disruptive behaviour "within the most recent thirty (30) calendar days."[4]
The frequency section sets guidelines, not a ceiling: more than 30 hours a week is high frequency, 20 to 30 moderate, 10 to 20 targeted or focused, and 5 to 10 or less maintenance or consultative. High frequency needs Autism Severity Level 2 or 3 with the diagnostic evaluation attached, goals tied to elopement, aggression, self-injury, property destruction or severe disruption, and an FBA or BIP; moderate needs documentation showing two or more of the listed criteria (Severity Level 2 or 3 with the evaluation attached, goals for moderate challenging behaviour that is not age-congruent) and also requires an FBA or BIP; the targeted and maintenance tiers need no FBA or BIP. Requests above these guidelines go to physician and BCBA consultant review. OHCA may ask for more support if behaviours have not improved within a year of at least 85% attendance.[4]
The initial request carries a comprehensive behavioral assessment, an FBA, a BSP if applicable, the treatment plan and OHCA's initial prior-authorization template, plus medical history and prior treatment response, caregiver interviews and rating scales, direct observation data, prior ABA history, a daily schedule by hour with each staff member's credentials, and the other therapies (OT, PT, speech) the child receives and when. The treatment plan is not valid until the supervising BCBA or licensed psychologist, the parent or guardian, and any minor aged fourteen or older have signed and dated it. The OHCA form "must be filled out completely or the request will be considered as incomplete." For fee-for-service members the typed form is faxed to OHCA at 405-530-7260; SoonerSelect members' requests go to their plan, because OHCA directs members to the plan for "prior authorizations."[3][5][14][17]
Settings are drawn tightly. "ABA services are not allowed in a daycare setting or school setting, without OHCA approval. If approved, it will be time-limited to three (3) months or less," with a plan to titrate support to school staff; a move into private school gets the same three-month limit. ABA must be one-on-one and face-to-face except for family adaptive treatment guidance, and the family is expected to attend at least 85% of treatment each review period. Telehealth is allowed ("in-person service delivery, telehealth, or a hybrid") if the modality and its justification are written into the PA template and treatment plan. On billing, RBT and supervision hours may be billed concurrently only when the PA request sets out the criteria and the BCBA or psychologist actually directed the RBT; "ABA is not allowed to be billed concurrently during any other therapies (i.e., OT, PT speech, etc.)"; hours approved for one CPT code cannot be used for another; and parent training must be delivered by the BCBA or BCaBA, never the RBT.[3][5][14][17]
The exclusion list is worth reading before writing goals: academic goals, performative social norms, school or daycare shadowing and aide work, services owned or delivered by the child's parent or other family member, experimental treatment, services for caregiver or provider convenience such as respite, and ABA authorized for toilet training, OT or speech therapy.[3][5][14][17]
OAC 317:30-5-315 is where Oklahoma authorizations are most often lost on process. The "Extension request may only be submitted seven (7) calendar days prior to the end date of the most recent request. Late submissions may result in a technical denial and loss of days." The extension form must be complete, and the packet shows eligibility still met, reduced target-behaviour frequency (or a modified plan), the daily schedule with staff credentials, progress toward goals, an updated FBA and BIP as appropriate, and the other therapies the child receives.[6][4]
Parent training is a hard condition. A first extension asking for more RBT hours needs parent training by the BCBA or BCaBA "at minimum of an hour (1) per week for three (3) months", later increases need two hours a week for three months, start and stop times go on the request, and "Absence or less than two (2) hours per month of appropriate parent training/involvement documented in the record will result in a reduction of hours and possibly denial of services." Families should hear this at intake, not at the first reduction. Every extension also updates the discharge plan, and a discharge notification form is due when a child completes treatment or moves provider.[6][4]
SoonerSelect health plans took over most SoonerCare members on April 1, 2024 across all 77 counties. Members choose among Aetna Better Health of Oklahoma, Humana Healthy Horizons and Oklahoma Complete Health, and OHCA says the plans "cover all services that SoonerCare fee-for-service covers" and "all medically necessary health and behavioral health services, except dental services" — no ABA or behavioral-health carve-out. Once a member picks a plan, they "correspond directly with that plan" for ID cards and prior authorizations. Children in foster care, former foster youth, children receiving adoption assistance and juvenile-justice-involved children go to the Children's Specialty Program instead, and OHCA states "Oklahoma Complete Health serves these members."[16][17][18][19]
The exclusions matter for autism. OHCA's SoonerSelect fact sheet lists as not eligible, among others, "Individuals determined eligible for Medicaid on the basis of age, blindness or disability (ABD)" and "Individuals enrolled in a §1915(c) waiver" — so a child on SSI-based Medicaid or a DDS waiver keeps traditional SoonerCare, and OHCA or its designated agent handles the ABA authorization. American Indian and Alaska Native members may opt in but are not required to. Check plan assignment on every intake: providers can confirm it through the OHCA Provider Helpline at 800-522-0114, option 1. Until July 1, 2027, state law requires SoonerSelect plans to pay in-network providers at least 100% of the OHCA fee schedule unless the provider agrees to a value-based arrangement.[16][17][18][19]
Oklahoma licenses behavior analysts. Under 59 O.S. § 1928 as in force through October 31, 2026, a "Licensed behavior analyst" is a BCBA "licensed by the Developmental Disabilities Services Division" of OKDHS, a certified assistant behavior analyst is a BCaBA certified by DDS, "No person shall practice applied behavior analysis without obtaining a license or certification," and supervisees practise only under a licensed behavior analyst; licensed human services professionals (psychologists, LPCs, LCSWs, OTs, SLPs and others) may practise ABA within scope. SB 1557 (Laws 2026, c. 392) moves licensure to the State Board of Examiners of Psychologists effective November 1, 2026, adds a national criminal history check for applicants, and keeps renewal on April 30 of odd-numbered years. OHCA's rule still reads "licensed by ... OKDHS DDS", so expect the SoonerCare enrollment documents to follow the move.[20][21][2]
The questions that decide whether a family can start with Oklahoma Medicaid (SoonerCare / SoonerSelect) - Oklahoma Health Care Authority, and what they have to bring. Each maps onto something intake should ask on the first call.
Under 21. OAC 317:30-5-313 requires that "The member is under twenty-one (21) years of age," and OHCA provides ABA "under the EPSDT benefit" (OAC 317:30-3-65.12). No lower age bound is set. (OHCA’s provider application page words it as "ages 21 and younger"; the rule text says under 21.)[4][9][14]
The comprehensive diagnostic evaluation or clinical assessment "will only need to be completed at the first initiation of ABA services and should be no older than two (2) years old." No annual or biannual update is required, but OHCA may ask for one if diagnosis and recommendations are unclear or there are significant medical or behavioral changes, and a member who changes agencies must supply the evaluation during the initial authorization period. Separately, disruptive behaviour must be documented within the most recent 30 calendar days.[4]
A definitive ASD diagnosis from one of: pediatric neurologist or neurologist; developmental pediatrician; licensed psychologist; psychiatrist or neuropsychiatrist; other licensed physician experienced in the diagnosis and treatment of ASD; or an interdisciplinary team of a licensed psychologist, physician, physician assistant or APRN. The provider must be in Oklahoma or within 50 miles of the border (OAC 317:30-3-89 through 92); out-of-state evaluations are accepted only if they meet the documentation standard and come from one of these disciplines.[4]
No single instrument is mandatory. The evaluation must include a complete medical and social history and be "based on criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM)", and "may also include scores" from formal tests such as the ADI-R, ADOS-2 or CARS "or other tools with acceptable psychometric properties." "Screening scales are not sufficient to make a diagnosis and will not be accepted as the only formal scale." For the ABA clinical assessment itself, OHCA cites validated measures such as the Vineland, and accepts supporting assessments such as the ABLLS-R, AEPS and VB-MAPP with the PA request.[4][3][5]
Allowed with justification. "ABA treatment may be rendered via in-person service delivery, telehealth, or a hybrid," the modality must be defined in the PA template and treatment plan, and the provider must explain how telehealth benefits the member and parents. OHCA’s list of medical codes allowed for telehealth (updated 8/10/2026) includes 97151, 97155 and 97156 but not 97153, so technician-delivered treatment is in person. Telehealth claims carry the appropriate modifier, minors need annual written parent consent, and documentation must show the service was delivered by telehealth and where.[5][12][7][11]
Oklahoma statute sets the clock. 56 O.S. § 4002.6(E): "If a contracted entity or the Authority requires prior authorization of a health care service," the decision is due "for urgent health care services, within seventy-two (72) hours of obtaining all necessary information" and "for non-urgent health care services, within seven (7) days of obtaining all necessary information"; if the provider submitted everything through the plan’s authorized PA system and the deadline is missed, the services "are deemed authorized." The approval must state its duration or expiry date, a plan may not revoke an authorization used within 45 business days, and a new SoonerSelect plan must honor the previous plan’s authorization for at least the first 60 days. Federal ceilings sit alongside: 42 CFR 438.210(d) (plans) and 440.230(e) (fee-for-service) cap standard decisions at 7 calendar days after the request is received from January 1, 2026, and expedited ones at 72 hours. Reauthorization lead time is fixed by OHCA rule: extensions "may only be submitted seven (7) calendar days prior to the end date."[23][24][25][6]
SoonerCare pays last. "As the Medicaid Agency, the Oklahoma Health Care Authority (OHCA) is the payer of last resort," so a commercial or absent-parent policy must be billed first and the EOB or denial attached. The family must meet both plans’ rules, including network rules. Oklahoma adds a useful line: "The state’s authorization that an item or service is as covered under the state plan ... shall meet the prior authorization requirements of the primary insurer." A provider paid by another source after OHCA paid must refund OHCA, and cannot bill the family for the balance other than copays. Exceptions to payer-of-last-resort are IHS care, IEP/IFSP school-based services and Crime Victims Compensation. Federal rule 42 CFR 433.139 lets states pay first and chase for EPSDT preventive pediatric services, but OHCA’s rule does not describe ABA that way, so bill the primary first. TRICARE pays ahead of Medicaid (32 CFR 199.8: "In any double coverage situation involving Medicaid, CHAMPUS is always the primary payer").[13][26][27]
OHCA’s ABA rules require no physician referral or order: the gate is the definitive diagnosis plus prior authorization submitted by the contracted ABA provider "to the Oklahoma Health Care Authority (OHCA) or its designated agent." SoonerSelect plans use PCPs who "refer you to specialists when needed," so whether a plan requires a PCP referral for ABA is a plan question.[5][4][16]
Ask the plan: The member’s SoonerSelect plan (Aetna Better Health 844-365-4385, Humana 855-223-9868, Oklahoma Complete Health 833-752-1664) — ask whether ABA needs a PCP referral on file; fee-for-service needs none under the OHCA rule.
Coverage decides whether Oklahoma Medicaid (SoonerCare / SoonerSelect) - Oklahoma Health Care Authority 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.
RBTs "must obtain ongoing supervision for a minimum of five percent (5%) of the hours they spend providing behavioral-analytic services each calendar month" and practise "under the close and ongoing supervision of a BCBA"; BCaBAs work under a SoonerCare-contracted BCBA. Concurrent RBT and supervision time is billable only when the PA request lays out the criteria and the BCBA or licensed psychologist met with the member or caregiver and directed the RBT (treatment integrity, new protocols, goal selection, family collaboration, data review, discharge planning) using behavioral skills training. The treatment plan must include training and supervision for BCaBAs and RBTs, and assessments must be completed by the BCBA.[2][5][3]
Allowed, with conditions. "Providers may only concurrently bill RBT and supervision hours when the following criteria is outlined in the prior authorization request," and the BCBA or licensed psychologist must have directed the RBT in session. "ABA is not allowed to be billed concurrently during any other therapies (i.e., OT, PT speech, etc.)," and "ABA hours approved for one CPT code cannot be used in place of another."[5]
No per-day unit cap is published. Limits are authorization-based: units granted for 1–6 months, intensity guidelines (>30, 20–30, 10–20 and 5–10 or fewer hours a week) with anything above them sent to physician and BCBA consultant review, and the FBA capped at 32 units (8 hours), requestable once every six months. Services are one-on-one only, except family adaptive behavior treatment guidance.[4][5][7]
Every assessment and treatment service must record the date, start and stop time for each session or unit billed, the physical location, the "Signature of the provider(s) rendering services" and their credentials, goals addressed, methods, progress, the member’s response and any new problems. Treatment plans and updates are "not valid until all signatures are present": the supervising BCBA or licensed psychologist, a parent or legal guardian, and any minor aged 14 or older, each dated with month, day and year.[3]
Home, community or clinic ("ABA may be provided in a variety of settings, including home, community, or clinical"). "ABA services are not allowed in a daycare setting or school setting, without OHCA approval. If approved, it will be time-limited to three (3) months or less," with a plan to fade support to school staff; private-school transitions are also capped at three months. School or daycare shadowing and aide work is excluded. Telehealth is allowed if justified in the PA (97151, 97155, 97156 on OHCA’s telehealth code list).[1][5][12]
Payment goes to the contracted, licensed provider, not the supervisee: "Payment is not made to under supervision ABA practitioners/paraprofessionals, including but not limited to, BCaBAs and RBTs," and OHCA’s provider page says payment for a BCaBA or other supervised practitioner "may only be made to his or her supervisor, or the employing agency or corporate entity." The RBT "works under the license number of a BCBA." Every staff member must still be individually contracted with OHCA, and the rule adds that "All ABA services should be billed under the rendering provider that performed the services." Telehealth services take the appropriate modifier.[7][14][2][5]
Yes. SoonerCare covers ABA for members under 21 with a definitive ASD diagnosis, as an EPSDT benefit under OAC 317:30-5-313. Most children get it through a SoonerSelect plan; children eligible through disability (ABD) or a 1915(c) waiver stay in fee-for-service SoonerCare.
Four: 97151, 97153, 97155 and 97156. The July 1, 2026 SoonerCare fee schedule pays $17.35 per 15-minute unit for 97153 and $23.55 per unit for the other three.
The comprehensive diagnostic evaluation should be no older than two years when ABA first starts. After that no annual re-evaluation is required, unless OHCA asks for one or the child changes agencies.
One to six months of units, as clinically indicated. Extensions can only be submitted in the seven calendar days before the current end date; late submissions risk a technical denial and lost days.
Effectively yes. A first extension asking for more RBT hours needs at least one hour a week of BCBA or BCaBA parent training for three months, later ones two hours a week, and under two hours a month of documented involvement reduces hours and can end services.
