Blue Cross and Blue Shield of Vermont is one of only two carriers selling individual and small-group coverage in Vermont (MVP is the other), and its policy also covers self-funded (ASO) employer groups it administers. Its ABA rules are unusual. It stopped requiring prior authorization for ABA in 2025. Instead, its medical policy caps each ABA code at a number of hours per plan year and treats hours beyond the cap as investigational.
Three layers apply: Blue Cross VT’s Corporate Medical Policy 3.01.VT201, Vermont’s mandate in 8 V.S.A. § 4082, and the plan’s funding type. Blue Cross VT says plainly that "not all groups are required to follow the Vermont legislative mandates," and that self-funded (ASO) employer plans and Federal Employee Program members may have different benefits.
Blue Cross VT announced that "beginning July 1, 2025, we are eliminating prior authorization requirements for applied behavior analysis." The current Corporate Medical Policy 3.01.VT201 (effective August 1, 2025) puts it in the coding table: every ABA code is "Prior Approval NOT Required." In place of authorization, the policy sets plan-year maximums: 97152 and 0362T, 60 hours (240 units) each; 97153, 1,560 hours (6,240 units); 97155, 312 hours (1,248 units); 0373T, 156 hours (624 units); 97156 and 97157, 52 hours (208 units) each; 97154 and 97158 combined, 72 hours (288 units). 97151 has no stated maximum. "ABA treatment services beyond the maximum/allowable units as outlined within this policy are considered investigational." The policy’s 2025 revision also removed its age-21 limit.[2][1][3]
No prior approval does not mean no review. Claims must meet the medical-necessity criteria, and Blue Cross VT "reserves the right to conduct audits" and "recoup all non-compliant payments." To qualify for an assessment, you need a documented attempt to get prior evaluation records. You also need documentation from the primary care provider, psychiatrist or psychologist of the ASD diagnosis using a tool such as CARS, ADOS, ADI-R or GARS (or a psychologist’s report with standardized IQ testing for intellectual disability), a DSM-5 severity rating, and a note of current school supports. Continued treatment is expected to show progress against baseline on graphed targets and a VB-MAPP Transition Scoring Form or an alternative such as AFLS or Essential for Living: at least 20% improvement at five to six months, 40% at eleven to twelve, and 75% from seventeen to eighteen months on. NEHP/ABNE members whose care Blue Cross VT manages were put under ABA prior approval in 2023, and the current policy warns that they "may have different benefits," so check those cards separately.[2][1][3]
Vermont’s autism mandate is 8 V.S.A. § 4082, "Early childhood development disorders." It is the old § 4088i under a new number: Act 11 of 2025 recodified Title 8’s health insurance chapter effective September 1, 2025, so plan documents and carrier policies that still cite § 4088i are pointing at the same law. The statute says a health insurance plan "shall provide coverage for the evidence-based diagnosis and treatment of early childhood developmental disorders, including applied behavior analysis supervised by a nationally board-certified behavior analyst, for children, beginning at birth and continuing until the child reaches 21 years of age." The disorders covered are broader than autism: any childhood impairment with functional limits and a DSM or ICD diagnosis, "but does not include a learning disability." The statute sets no dollar or hour cap. Instead, "the amount, frequency, and duration of treatment … shall be based on medical necessity and may be subject to a prior authorization requirement." Cost sharing may not be higher than for any other physical or mental condition. ABA must be covered when "provided or supervised by a licensed health care professional … or who is a nationally board-certified behavior analyst," including in the "natural environment" (a home or child care setting). Plans may review the treatment plan "based on the needs of the covered individual," but for children under eight "not more frequently than once every six months." Two limits matter. A major medical plan does not have to provide benefits beyond the ACA essential health benefits. And the statute leaves IEP and early-intervention obligations in place: a plan "shall not reimburse services provided under 16 V.S.A. § 2959a." On who is bound: chapter 107 defines a health insurer to include an HMO, a nonprofit hospital or medical service corporation and, "to the extent permitted under federal law, any administrator of an insured, self-insured, or publicly funded health care benefit plan." The State of Vermont employee plans are expressly included. Self-funded private employer plans follow ERISA, so check how the plan is funded first.[6][7]
Vermont licenses behavior analysts. Under 26 V.S.A. chapter 95, administered by the Office of Professional Regulation, a person may not practice "as an applied behavior analyst or an assistant behavior analyst unless currently licensed." A BCBA can get a license by endorsement on the strength of BACB certification alone (§ 4923). Three rules shape the work. A licensee may practice only "upon, and within the scope of, a referral from a licensed health professional or school official." Diagnosis is outside the scope: behavior analysis "shall not include … diagnosis of mental health or developmental conditions" (§ 4928). And a licensed assistant behavior analyst needs at least "five hours per month of off-site case supervision" by a licensed behavior analyst (§ 4929). Technicians are not licensed. The chapter does exempt school-employed paraprofessionals working "under the close direction" of a licensed supervisor, and people employed by or under contract with the Agency of Human Services. For BCBAs outside Vermont, 26 V.S.A. chapter 56 lists applied behavior analysis among the professions eligible for out-of-state telehealth credentials. A telehealth license covers up to 20 unique Vermont clients over a two-year term. A telehealth registration covers up to 10 clients over 120 days and cannot be renewed. Either one allows telehealth only, never in-person care. Both require a credential "in good standing in any other U.S. jurisdiction." BACB certification is not issued by a jurisdiction, so read literally, a BCBA from a state that does not license behavior analysts needs the full Vermont license by endorsement. Treating a Vermont client by telehealth without one of these credentials is unauthorized practice.[9][10][21][11]
Blue Cross VT enforces a 180-day filing limit "regardless of date of service" from November 1, 2026. New claims must be accepted into its system within 180 calendar days of the date of service for professional claims, or within 180 days of the primary carrier’s processing when another payer is primary. Late claims "cannot be appealed or billed/collected from the member." Phone calls and emails are no longer proof of timely filing. Payment policy CPP_03 (effective January 1, 2026) lists every ABA code, 97151 through 97158, 0362T and 0373T, as eligible for telemedicine with modifier -95, billed POS 02 or POS 10 (home). Blue Cross VT can contract only with providers "physically located in Vermont or a county contiguous to Vermont." A provider outside that area treating by telemedicine bills the local Blue plan where they are located.[5][4][12][13][6][17][14]
Vermont’s claims and prior-authorization rules bind health plans, defined to include insurers, HMOs and, "to the extent permitted under federal law, any administrator of an insured or self-insured plan." Under the prompt-pay statute (18 V.S.A. § 9418), a plan must pay a claim, or notify you in writing that it is contested or denied, within 30 days of receipt. It must acknowledge an electronic claim within 24 hours after the start of the next business day. Unpaid uncontested claims accrue interest at 12 percent a year. The prior-authorization statute (18 V.S.A. § 9418b, as amended through 2025) sets the timeline. A completed non-urgent request must be decided "within two business days following receipt," and receipt acknowledged within 24 hours. Urgent requests are decided within 24 hours. A missed deadline means the request "shall be deemed to have been granted." An approval lasts "for the duration of the prescribed or ordered treatment … or one year, whichever is longer," and for ongoing treatment a plan may not require renewal more often than every five years. The mandate separately lets plans review an ABA treatment plan (every six months at most for children under eight), so ask how the carrier squares the two. Plans may not require prior authorization for services ordered by an in-network primary care provider (out-of-network services excepted). Plans must also post their current prior-authorization list publicly. A self-funded ERISA plan follows 29 CFR 2560.503-1 instead: pre-service decisions within 15 days (one 15-day extension), urgent ones within 72 hours, and at least 180 days to appeal a denial. After internal appeals, Vermont’s external review (8 V.S.A. § 4063) is open for medical-necessity and experimental denials involving at least $100, for a $25 fee.[5][4][12][13][6][17][14]
Blue Cross VT manages prior approval for its own members, FEP members, and New England Health Plan / Access Blue New England (NEHP/ABNE) members whose assigned PCP is in Vermont. "We do not oversee prior approval of other Blue Plan members (BlueCard members)." For any other Blue plan’s member, including an NEHP/ABNE member without a Vermont PCP, "Contact the member’s Blue Cross and Blue Shield Plan. Do not submit PA request to Blue Cross VT." The home plan’s requirements are found through the Medical Policy Router on the Provider Policies page.[19][22]
For Blue Cross VT members treated outside Vermont: Blue Cross VT’s April 2026 mental health notice says prior approval or pre-notification "continues to be required if the services are provided by out-of-state (even if that provider/facility is in the BlueCard network)" for the higher levels of care it names.[19][22]
The questions that decide whether a family can start with Blue Cross and Blue Shield of Vermont, and what they have to bring. Each maps onto something intake should ask on the first call.
No expiry on the diagnosis. Continued coverage is tied to measured progress against baseline (20%, 40% and 75% improvement at roughly 6, 12 and 18 months) on graphed targets and a VB-MAPP Transition Scoring Form or an alternative.[1]
Documentation from "the primary care provider, psychiatrist, or psychologist" of the ASD diagnosis. Intellectual disability needs an official psychologist’s report with standardized intelligence testing.[1]
ASD documented with a tool such as the Childhood Autism Rating Scale, the Autism Diagnostic Observation Schedule, the Autism Diagnostic Interview-Revised and/or the Gilliam Autism Rating Scale, with DSM-5 severity. Progress tracked with a VB-MAPP Transition Scoring Form or an alternative such as AFLS or Essential for Living.[1]
Blue Cross VT requires no prior approval and the policy names no separate referral, but the assessment criteria need diagnosis documentation from the PCP, psychiatrist or psychologist. Vermont’s licensure law adds its own gate: a Vermont-licensed behavior analyst may practice only "upon, and within the scope of, a referral from a licensed health professional or school official" (26 V.S.A. § 4928), so keep that referral on file whatever the plan requires.[1][9]
All ABA codes. CPP_03 (eff. 01/01/2026) lists 97151–97158, 0362T and 0373T as telemedicine-eligible with modifier -95, billed POS 02 (not at home) or POS 10 (home), for providers located in Vermont or a contiguous county (or temporarily out of state for up to six months). For a fully insured Vermont plan, 8 V.S.A. § 4098a requires coverage of services delivered by telemedicine (live audio-video) "to the same extent" as in person, from any originating site including "the patient’s home," at the same rate for equivalent codes and modifiers (subject to the provider contract). A plan may still limit coverage to services that are "medically necessary and are clinically appropriate for delivery through telemedicine." Self-funded plans are outside the statute.[4][8]
Policy 3.01.VT201 removed its age-21 limit in its 2025 revision, so the policy sets no age cap. Self-funded and FEP plans follow their own documents. For fully insured Vermont plans, 8 V.S.A. § 4082 requires ABA coverage from birth until the child reaches 21, with no dollar or hour cap in the statute. Self-funded ERISA plans are outside it, so plan funding type decides whether that binds.[1][6]
Ask the plan: Blue Cross VT customer service on the card: confirm the group is fully insured (not ASO or FEP) and that the plan has no age term of its own.
Not applicable for Blue Cross VT’s own members: ABA needs no prior approval. Where a plan does require it (NEHP/ABNE, for example), 18 V.S.A. § 9418b requires a decision on a complete non-urgent request within two business days and an urgent one within 24 hours, or the request is deemed granted. Self-funded ERISA plans follow 29 CFR 2560.503-1 (15 days, urgent 72 hours).[1][3][13][17]
Ask the plan: Blue Cross VT customer service: confirm whether the member’s plan (NEHP/ABNE, ASO or FEP) adds an ABA authorization step.
No Vermont rule fixing the order of benefits between two parents’ group plans was confirmed this run, so take the order from Blue Cross VT at benefits verification. A self-funded plan sets its own order. If the child also has Vermont Medicaid, Blue Cross VT pays first. A Vermont insurer may not consider Medicaid eligibility when paying claims (8 V.S.A. § 4024), and Medicaid is the payer of last resort (42 CFR 433.139). Vermont Medicaid will cover what the primary plan denies only after you have used every level of the primary plan’s appeals and, where the service costs more than $100, a Department of Financial Regulation review. TRICARE pays after this plan (10 U.S.C. 1079(i)(1)); CHAMPVA is the last payer (38 CFR 17.270).[15][23][16][24][25]
Ask the plan: Ask Blue Cross VT for the coordination-of-benefits order and send its Coordination of Benefits Questionnaire when other coverage exists; record every other coverage the child has.
Coverage decides whether Blue Cross and Blue Shield of Vermont 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.
ABA is "provided by, or … performed under the supervision of" a program manager or lead behavioral therapist who is a BCBA, another state-licensed or certified behavior instructor, or a provider whose legal scope includes behavior analysis. A BCaBA or licensed assistant behavior analyst "may not function as a program manager or lead behavioral therapist and may not provide ABA services without supervision." No numeric ratio is published. Vermont law requires at least five hours a month of off-site case supervision for a licensed assistant behavior analyst.[1][9]
Not medically necessary, per policy 3.01.VT201. That covers more than one clinician (program manager and technician, for example) "providing direct (ABA) treatment services to the same member at the same time," ABA delivered at the same time as another therapy such as speech, more than one program manager or agency at a time, and direct treatment to more than one member in a session (social-skills groups excepted).[1]
No daily cap; plan-year maximums per code: 97153, 1,560 hours; 97155, 312; 0373T, 156; 97152 and 0362T, 60 each; 97156 and 97157, 52 each; 97154 and 97158 combined, 72. Units beyond these are treated as investigational.[1]
Home or office. Policy hours "will be for time of treatment outside of the school setting (i.e., home or office setting)," with the school responsible for ABA by an aide during the school day. Services that belong in an IEP are excluded. Telemedicine is billed POS 02 or POS 10.[1][4]
The policy’s eligible providers are "qualified healthcare professionals practicing within the scope of their license(s)." Assessment components may be done by a BCaBA but "must be reviewed by" a BCBA. Blue Cross VT contracts only with providers physically located in Vermont or a contiguous county; others bill their local Blue plan. Whose NPI goes on a technician’s line is not stated.[1][4]
Policy 3.01.VT201 requires treatment protocols, data collected for each goal and documented progress, but does not say who signs a session note or by when.[1]
Ask the plan: Blue Cross VT Provider Relations, (888) 449-0443 option 1, or providerrelations@bcbsvt.com: ask for the documentation standard in the provider agreement or provider manual.
No. Blue Cross VT removed ABA prior authorization in 2025; policy 3.01.VT201 (eff. 08/01/2025) marks every ABA code "Prior Approval NOT Required." NEHP/ABNE, FEP and self-funded groups may have different rules.
Yes, per plan year by code: for example 1,560 hours of 97153 and 312 hours of 97155. Hours beyond the policy maximum are treated as investigational. The Vermont mandate itself sets no hour or dollar cap; amounts are to follow medical necessity.
Yes. Its telemedicine policy CPP_03 lists every ABA code, including 97151 and 97153, with modifier -95, billed POS 02 or POS 10. The provider must be located in Vermont or a contiguous county to bill Blue Cross VT directly.
For moderate or severe intellectual disability, yes (F71, F72), documented by a psychologist’s report with standardized IQ testing. Mild intellectual disability without ASD is not covered.
180 calendar days from the date of service for professional claims (or from the primary carrier’s processing date when another plan is primary), fully enforced from November 1, 2026. Late claims cannot be billed to the member.
Yes, to practice ABA in Vermont, including by telehealth. A BCBA can be licensed by endorsement on BACB certification, and clinicians licensed in another state can use Vermont’s telehealth license or registration for limited caseloads.
No. Blue Cross VT says it does not oversee prior approval for BlueCard members, including NEHP/ABNE members without a Vermont PCP. Contact the member’s own Blue plan, using the Medical Policy Router on Blue Cross VT’s Provider Policies page to find its requirements.
