Aetna ABA coverage in Massachusetts: the intake guide.

Twelve months, and it attaches to the functional measure rather than to the diagnosis. Aetna's medical-necessity criteria require that "There is demonstration of functional impairment on a standardized scale of functioning in the past 12 months," with the impairment at least one standard deviation below the population mean or representing a significant risk of harm to self or others. The ASD diagnosis itself carries no stated shelf life — so a family with an older diagnostic report is not blocked, but a stale adaptive score is.^[9]

A scope-of-practice test rather than a specialty list. Aetna requires "a DSM-V diagnosis of Autism Spectrum Disorder (ICD-10: F84.0; F84.3 - F84.9) obtained by an appropriate provider," and defines that as a "licensed psychologist/psychiatrist, physician or other health care professional qualified to diagnose mental health conditions within their scope of practice." Note the code range: F84.2 (Rett syndrome) sits outside the listed set, and ABA for diagnoses other than ASD is treated as experimental.^[9]

Aetna names adaptive-functioning instruments, not autism diagnostic instruments. The medical-necessity criteria require demonstrated functional impairment "on a standardized scale of functioning in the past 12 months. For instance, the Vineland Adaptive Behavior Scales 3 (VABS-3), the Adaptive Behavior Assessment Scale (ABAS), VB-MAPP or ABLLS," and quality-of-care elements add "Repeated measurement with standardized measures to assess progress." No ADOS-2 or ADI-R requirement appears anywhere — the instrument Aetna asks for is the one that sizes the hours, and the level-of-impairment calculation is what justifies the number requested.^[9]

Aetna sets no upper age limit in its national medical-necessity criteria. The ABA Medical Necessity Guide gives age only as clinical shape, not as a gate: comprehensive ABA carries a "typical age range" of 0-7 years at 10-25 hours a week for 1-2 years, while focused ABA is listed for "All ages" at 1-20 hours a week. The binding age question is the legal layer underneath: ARICA bars fully-insured Massachusetts plans from imposing any age limit on ASD diagnosis and treatment, so on a fully-insured card there is no upper bound at all; a self-funded ERISA plan answers to its own plan document. Establish funding type before quoting an age answer.^[9][5]

Ask the plan: The member's benefit document and Aetna precertification — funding type decides whether the state mandate or the plan document sets the age boundary.

Depends on how the plan is funded. For a fully insured plan issued in Massachusetts, M.G.L. c. 176O § 12 sets the clock. An initial determination is due "within two working days of obtaining all necessary information." An approval is phoned to the provider within 24 hours and confirmed in writing within two working days after that. A concurrent review (reauthorization) is due "within one working day of obtaining all necessary information," and during that review "the service shall be continued without liability to the insured until the insured has been notified of the determination." These clocks start when the file is complete, not when the request arrives, so a request missing information is not yet on the clock. A self-funded employer plan follows the federal ERISA claims rule instead. Urgent decisions are due within 72 hours. Other pre-service decisions are due within a reasonable time "but not later than 15 days after receipt of the claim," with one 15-day extension. A request to extend an ongoing course of treatment that involves urgent care must be decided within 24 hours if made at least 24 hours before the authorization expires. Aetna publishes no ABA-specific decision clock or reauthorization lead time in the documents this guide cites.^[11][12]

Ask the plan: Benefits verification call or Availity: ask whether the plan is fully insured in Massachusetts (c. 176O clock) or self-funded ERISA (72-hour / 15-day clock), and how far ahead of expiry Aetna wants the ABA reauthorization.

Depends on the family and on plan funding. For plans regulated by the Massachusetts Division of Insurance, 211 CMR 38.05 sets the order. The plan covering the person "other than as a dependent" pays before the one covering them as a dependent. For a child whose parents are married or living together, "The Plan of the parent whose Birthday falls earlier in the calendar year is the Primary Plan." If both parents share a birthday, the plan that has covered that parent longer pays first. For parents who are divorced, separated or living apart, a court decree that makes one parent responsible controls. With no decree, the order is the custodial parent, then the custodial parent's spouse, then the non-custodial parent, then the non-custodial parent's spouse. A self-funded ERISA plan sets its COB rules in its own plan document. This plan pays before TRICARE ("By law, TRICARE pays after all other health insurance," except Medicaid and a few government programs). It also pays before CHAMPVA ("CHAMPVA is the last payer to OHI"). If the child also has MassHealth (for example CommonHealth to cover copays), this plan pays first. MassHealth's rule then requires the provider to be in this plan's network and to follow its authorization rules. A denial for missing PA or for being out of network forfeits the MassHealth secondary payment, and MassHealth needs this plan's final disposition (EOB) on the claim.^{[13][14][15][16][17]}

Ask the plan: Benefits verification: ask whether the plan is fully insured in Massachusetts or self-funded, whether the child is on a second parent's plan (both parents' birthdays, custody or court-decree terms), and whether the child also has MassHealth, TRICARE or CHAMPVA.

Not published. Aetna's ABA Medical Necessity Guide and its ABA clinical policy bulletin set a diagnosis requirement, a precertification requirement and a provider-licensure requirement, but state no referral or physician order as a condition of coverage. The gate that does exist is precertification itself — required for both the assessment and treatment.^[9]

Ask the plan: Aetna precertification/provider services at the number on the member's ID card, and the member's benefit document — ask whether the plan layers a referral requirement on behavioral health.

Not published. Aetna's ABA materials set medical-necessity criteria and precertification requirements for 97151-97158, 0362T and 0373T but say nothing about remote delivery, telehealth modifiers or place-of-service codes. ARICA bars fully-insured Massachusetts plans from imposing limits on ABA that are less favorable than those on physical conditions, which is a benefit-design argument rather than a published telehealth rule.^[9][5]

Ask the plan: Aetna provider services and the member's benefit document — confirm which ABA codes pay by telehealth and with which POS code before scheduling remote supervision or caregiver training.

Aetna sets a duty, not a number. Where a state mandate, plan document or contract allows services from someone neither state-licensed nor BACB-certified, “there must be supervision and direction of the unlicensed or non-certified providers in line with practice standards.” The ABA Medical Necessity Guide publishes no supervision percentage, ratio or caseload cap — the operative standard is professional practice plus whatever the contract adds.^[9]

The claim carries the analyst, not the technician. “Services must be provided directly or billed by licensed behavior analysts (in states with behavior analyst licensure laws), board-certified behavior analysts, or licensed psychologists where behavior analysis is within their scope of practice definition, unless state mandates, plan documents or contracts require otherwise.” The escape clause matters: a state mandate or your contract can move the line, so confirm before enrolling technicians.^[9]

Aetna does not publish a POS code list for ABA. The one place-of-service boundary it does state is the schools carve-out: pursuant to applicable law Aetna “is not required [to] provide services to a child under an individualized education program or any obligation imposed on a public school by the Individuals with Disabilities Education Act.” That is a limit on paying for what the IEP owes, not a blanket ban on the school setting — and it yields to a stronger state mandate. Where ABA is payable in a school, in the community or in a group home is a benefit-document question on Aetna plans. In Massachusetts the schools carve-out sits alongside ARICA, which governs fully insured plans — so read the state mandate first on a fully insured member and the plan document first on a self-funded one.^[9]

Ask the plan: The member’s benefit document, and Aetna provider services for whether school-setting ABA is payable on that plan.

Not published. Neither the ABA Medical Necessity Guide nor Aetna’s clinical policy bulletin on ABA addresses whether 97153 and 97155 may be billed for the same clock time; Aetna carries the concurrency question in its claim editing rather than in a public policy.

Ask the plan: Aetna precertification/provider services at the number on the member’s ID card, and the plan’s own reimbursement schedule — ask specifically whether 97155 pays alongside 97153 when analyst, technician and member are all face-to-face.

Not published. Aetna’s ABA documents set medical-necessity criteria and precertification requirements for 97151–97158, 0362T and 0373T, but no per-day unit ceiling and no statement of which MUE table applies.

Ask the plan: Aetna provider services; confirm before promising a family more than four hours a day of 97153.

Not published in Aetna’s ABA materials — no rule on who signs a session note or within what window.

Ask the plan: The Aetna provider manual and your participation agreement’s documentation clause.
