For a California intake team an Aetna card means three layers: Aetna’s national ABA policy (CPB 0554, CPB 0648 and the ABA medical necessity guide), California’s autism mandate, and the plan’s funding type deciding which binds. California adds a fourth wrinkle: Aetna’s own state supplement says outpatient behavioral health on fully insured plans no longer needs prior authorization, while its national ABA documents still require precertification — so confirm per member. Aetna runs no Medi-Cal plan in 2026: Aetna Better Health of California stopped operating on January 1, 2024.
Aetna covers ABA for autism spectrum disorder under CPB 0554 (with CPB 0648 for ASD) and its ABA medical necessity guide, and considers ABA experimental for other indications. Nationally, the behavioral health precertification list names all ten ABA codes (97151–97158, 0362T, 0373T), and form GR-69017-4 — the 7-26 version, which "Effective August 1, 2026 … replaces all other" ABA precertification forms — carries the clinical detail; it excludes only Maryland and Massachusetts. The guide has no California exhibit (Maryland is the only state exhibit) and Aetna’s CPB state-deviation page has no California entry for CPB 0554 or 0648.[2][3][5][6][8][7][9]
The California supplement (7/26) is where it gets complicated: "Beginning on March 1, 2024, behavioral health services performed on an outpatient basis to any fully insured commercial HMO, PPO, EPO, IFP or student health plan will no longer require prior authorization. All inpatient behavioral health services will require prior authorization." It neither names nor carves out ABA, while the June 2026 provider manual still says "Applied behavior analysis (ABA) services require prior authorization." Until Aetna settles it, call precertification for each fully insured member and keep the reference number. The supplement also tells HMO members assigned to a medical group or IPA to "follow the precertification process established by their medical group or IPA."[2][3][5][6][8][7][9]
California’s mandate is Health & Safety Code § 1374.73 for DMHC-regulated health care service plans (every HMO and many PPO/EPO products) and Insurance Code § 10144.51, its word-for-word twin for CDI-regulated insurance policies. Enacted by SB 946 in 2011 with a sunset, made permanent by AB 796 in 2016 and last amended by SB 402 (effective January 1, 2026), it requires every plan covering hospital, medical or surgical care to cover "behavioral health treatment for pervasive developmental disorder or autism" — defined to include "applied behavior analysis and evidence-based behavior intervention programs" — "in the same manner and … subject to the same requirements" as mental health parity under § 1374.72. The statute has no age limit and no dollar or visit cap. Treatment must be "prescribed by a physician and surgeon" or "developed by a psychologist," follow a treatment plan with measurable goals "reviewed no less than once every six months" by the qualified autism service provider, and may not be used for "respite, daycare, or educational services." Plans may still use "case management, network providers, utilization review techniques, prior authorization, copayments, or other cost sharing."[10][11][15][16][17][18]
Three newer layers matter at intake. SB 855 (§§ 1374.72, 1374.721; Ins. §§ 10144.5, 10144.52) requires medical-necessity decisions under "generally accepted standards," using the criteria of "the nonprofit professional association for the relevant clinical specialty," supplied "at no cost" — and bars limiting coverage because services "should be or could be covered by a public entitlement program, including … special education or an individualized education program, Medicaid." Aetna publishes no California-specific ABA criteria set; for a fully insured member, ask which criteria the review used. SB 402 (carrying AB 951) says a contract issued, amended or renewed on or after January 1, 2026 "shall not require an enrollee previously diagnosed with pervasive developmental disorder or autism to receive a rediagnosis to maintain coverage" and "shall not discontinue or delay existing treatment while waiting for a rediagnosis." Exempt: self-funded ERISA employer plans (outside state law), Medi-Cal plan contracts, specialized plans that do not deliver mental health services, and — for CDI policies — accident-only, specified-disease, hospital-indemnity and Medicare supplement policies.[10][11][15][16][17][18]
California has no behavior analyst license — it is absent from the BACB’s licensure table, and SB 402’s new Business & Professions Code chapter (§§ 4999.200–4999.202) is definitional only. A qualified autism service (QAS) provider is a BCBA ("certified by a national entity, such as the Behavior Analyst Certification Board") or a listed California licensee; a QAS professional (BCaBA-level behavior service providers under 17 CCR § 54342, or — since SB 805 — associate MFTs, ACSWs, APCCs and psychological associates) works under the provider’s supervision; and a QAS paraprofessional — the technician — is "an unlicensed and uncertified individual" supervised "at a level of clinical supervision that meets professionally recognized standards of practice." For Aetna that means BACB certification: its manual requires "national certification … from the Behavior Analyst Certification Board (BACB), or the practitioner must be licensed as a behavior analyst in the state in which they practice." Aetna publishes no California ABA fee schedule; rates are contract-negotiated (fee-schedule requests via Availity, 1-888-632-3862 for 10 codes or fewer, or FeeSchedule@aetna.com).[19][20][12][7][8]
Aetna does not publish an ABA-specific filing limit in the documents read; the number sits in the provider agreement. Aetna’s national provider manual says claim disputes "Must be submitted within contractual timeframes." For Aetna’s DMHC-licensed products (its HMOs and any DMHC-regulated PPO/EPO), state regulation sets the floor: no claim deadline "less than 90 days for contracted providers and 180 days for non-contracted providers after the date of service"; payment of a complete claim within 30 calendar days of receipt since January 1, 2026, with 15% annual interest from day 31 (H&S § 1371 as amended by AB 3275; the regulation’s 30 and 45 working days no longer control); and at least 365 days from the plan’s action to file a provider dispute, which must be decided within 45 working days (28 CCR §§ 1300.71, 1300.71.38). CDI-regulated insurance policies are outside these DMHC rules but face the same 30-calendar-day payment clock under Ins. Code § 10123.13 since 2026; self-funded ERISA plans follow their plan documents.[1][21][22][7]
Aetna publishes no requirement to report a referring or ordering provider on an ABA claim. Its office manual defines a clean claim as including “A corresponding referral (whether in paper or electronic format), if required for the applicable claim” plus “All the data elements of the UB-04 or CMS-1500 (or successor standard) forms (including but not limited to member identification number, National Provider Identifier (NPI), date(s) of service, and a complete and accurate breakdown of services).”[7][14]
A referral matters only on plans that require PCP referrals for specialist care. Those referrals must be issued before the visit (“Referrals should not be retroactive”), and “In Aetna Open Access® plans, referrals also are not necessary.” Aetna’s behavioral health manual lists direct access as the first way into care: members may reach behavioral health “Through direct access to the behavioral health provider,” through a recommendation from their PCP or another treating provider, or through an EAP referral.[7][14]
Joining the network: Aetna's participation criteria for ABA providers require services "provided directly or supervised by individuals licensed by the state or certified by the Behavior Analyst Certification Board as board-certified behavior analysts (BCBAs)"; a BCaBA or paraprofessional works under supervision, BCBAs must meet Aetna credentialing standards, and "All BCBAs, BCaBAs and paraprofessionals must meet state requirements." The criteria do not say the ABA network is open or closed in a given state.[13][14][7]
Out-of-network care and single case agreements: Aetna does not use the term "single case agreement" in these documents. Its behavioral health manual describes a "nonparticipating referral" — "a written or verbal request that we review" — that may be approved when a preferred clinician "isn't available in network (and the member's plan provides coverage for out-of-network services)," when the member is continuing or returning to treatment with a nonparticipating clinician "in certain circumstances," or when the PCP identifies a nonparticipating expert. Plans without referral requirements let members self-refer to participating or nonparticipating providers, paying their cost share; Aetna Open Access plans let members self-refer to any participating provider.[13][14][7]
Disputes: payment disputes on a finalized claim go through the Availity provider portal ("Dispute Claim" from Claim Status, then the Appeals dashboard, up to five 32 MB attachments) or the Disputes and Appeals page on Aetna.com. The behavioral health manual describes "One level of appeal" for payment decisions; pre-service and concurrent medical-necessity denials go through the member appeal process, and a provider appeal counts as "on behalf of the member" only with the member's written authorization. State rules may change the process.[13][14][7]
Authorizations and changing agencies: none of these Aetna documents says whether an ABA precertification is issued to the rendering NPI, the group or the TIN, or whether it moves with the child to a new agency; ask the precertification line on the member's card before the first session with the new agency.[13][14][7]
The questions that decide whether a family can start with Aetna in California, and what they have to bring. Each maps onto something intake should ask on the first call.
No expiry on the diagnosis itself; the clock runs on functioning — medical necessity requires "demonstration of functional impairment on a standardized scale of functioning in the past 12 months," at least one standard deviation below the mean or a significant risk of harm, and form GR-69017-4 adds re-evaluation "every 6 months" and "a repeat validated assessment … every 6-12 months." On fully insured California plans renewed on or after January 1, 2026, § 1374.73(c) bars requiring a rediagnosis to maintain coverage.[4][6][10]
A DSM-5 ASD diagnosis "obtained by an appropriate provider" — the guide names a "licensed psychologist/psychiatrist, physician or other health care professional qualified to diagnose mental health conditions within their scope of practice"; CPB 0648 lists professionals appropriate to ASD evaluation (BCBA, developmental pediatrician, neurologist, OT, PT, primary care provider, psychiatrist, psychologist, SLP and audiologist). Aetna’s California-only record-review items add "If member is 0-6 years of age, there is documentation of screening for autism spectrum disorder." LCSW: Aetna's test is scope of practice. California's LCSW scope statute, B&P § 4996.9, defines clinical social work to include "counseling and using applied psychotherapy of a nonmedical nature" and does not mention diagnosis (read in FindLaw's unofficial copy, current as of January 1, 2026; the official leginfo page blocks automated reads). It neither expressly grants nor bars an LCSW autism diagnosis, so ask the plan before relying on an LCSW-only diagnosis.[4][3][7][23]
CPB 0648 names ADI-R, ADOS-2, CARS-2 and the Asperger Syndrome Diagnostic Scale for the diagnosis; the guide requires a standardized functioning measure within the past 12 months, such as the Vineland-3, ABAS, VB-MAPP or ABLLS; GR-69017-4 also asks for "the member’s IQ, if available."[3][4][6]
Aetna’s national ABA documents require no physician referral or order — the guide’s only prescription language is the Maryland exhibit. Precertification (where it applies) is provider-initiated via Availity or the precertification line; GR-69017-4 supplies the clinical detail and "can’t [be used] to initiate a new precertification request." The California supplement routes HMO members in a medical group or IPA through that group’s process. The California mandate itself keys covered BHT to a physician prescription or a psychologist-developed plan on fully insured plans.[4][6][8][10]
Aetna’s national ABA policies set no age cap; the medical necessity guide’s table is "Typical" (comprehensive ABA for ages 0–7, focused ABA for all ages), and "If there is a discrepancy between this guideline and a member’s plan of benefits, the benefits plan will govern." For fully insured California plans, H&S § 1374.73 / Ins. § 10144.51 contain no age or dollar limit; self-funded ERISA plans are outside the statute.[4][10]
Ask the plan: Live benefits verification on the member ID (Availity) — fully insured vs. self-funded, then the plan’s own age terms.
Aetna's Telemedicine and Direct Patient Contact Payment Policy lists the ABA codes it pays by telehealth, by line of business. On commercial plans the eligible codes are 97151 (the assessment), 97153, 97155 (protocol modification, the code for BCBA direction of the technician), 97156 and 97157, billed with modifier GT, 95 or FR; 97152, 97154 and 97158 are checked for Medicare Advantage only. The posted policy shows a last review of June 2021, so treat the list as perishable. Aetna’s manual: "Aetna Behavioral Health offers telehealth services to all commercial fully insured members and to all commercial self-insured plan sponsors, unless those self- insured plan sponsors opt out," acting "within the scope of their license." California law (H&S § 1374.14) requires fully insured plans to cover telehealth on the same basis as in person.[24][7][25]
Ask the plan: Aetna Behavioral Health (1-888-632-3862) or Availity — which ABA codes are payable by telehealth on this plan, and with which POS and modifier.
Aetna publishes no ABA-specific clock ("The timing of the review incorporates state, federal, … and … NCQA requirements"), so the regulator’s applies. DMHC plans: H&S § 1367.01(h) — "not to exceed five business days" from receipt of the information reasonably necessary, 72 hours urgent. CDI policies: Ins. § 10123.135(h), the same. Self-funded ERISA plans: 29 CFR 2560.503-1 — pre-service "not later than 15 days after receipt of the claim," one 15-day extension, urgent within 72 hours. Reauthorization: progress is evaluated every six months.[7][26][27][28]
Ask the plan: At benefits verification ask whether the plan is DMHC, CDI or self-funded, then confirm the turnaround with Aetna precertification (1-888-632-3862).
No Aetna ABA-specific COB rule was read. The California floor: DMHC plans follow 28 CCR § 1300.67.13 and CDI policies 10 CCR § 2232.56 — the employee’s plan before the dependent’s; for a child of non-separated parents, the plan of the parent whose birthday falls earlier in the calendar year; then court decree, custodial parent, stepparent, non-custodial parent. If the child also has Medi-Cal, this plan pays first — Medi-Cal is payer of last resort (W&I § 14124.90) and the plan may not limit coverage because Medicaid could pay (H&S § 1374.72(h)). TRICARE pays after this plan (10 U.S.C. 1079(i)(1)); CHAMPVA is "the last payer" (38 CFR 17.270(b)). Self-funded plans use their plan document.[29][30][31][32][33]
Ask the plan: Ask Aetna at benefits verification for the member’s COB order (and whether a self-funded plan uses the birthday rule); Aetna’s COB billing tips document was not re-read this cycle.
Coverage decides whether Aetna in California 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.
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 ABA is in scope, with "supervision and direction of the unlicensed or non-certified providers in line with practice standards." The current guide also sizes supervision: "additional authorization may be provided for QHP protocol modification and direction at 1 to 2 hours per 10 hours of treatment by protocol, as well as authorization for caregiver training." California has no behavior analyst license, so BACB certification is the credential.[4][7]
No per-day unit cap. Hours are sized by the guide’s severity table — per domain (maladaptive behavior, social communication, self-care): none 0, mild 1–4, moderate 4–7, severe 7–10 hours a week — which "can be used as a guide," plus 1–2 hours of protocol modification per 10; typical intensity is 10–25 hours a week comprehensive, 1–20 focused. Coverage ends on the guide’s improvement thresholds (e.g. "improvement of two or more standard deviations in multiple domains"). On fully insured California plans the statute bars dollar or visit caps.[4][10]
Aetna has a general rule, not an ABA-specific one. Its medical-record standards apply to "all participating practitioners," who "agree to maintain medical records in a current, detailed, organized, and comprehensive manner." The core components are: "All entries are dated," "All entries are legible to someone other than the writer," and "All entries in the record must contain the provider's signature/initials or electronic identifier." Aetna audits records against these at least every two years, with an 85% performance goal. Aetna's ABA documents do not say whether the technician, the supervising BCBA or both sign a session note, or how soon after the session it must be signed. Each person who writes an entry should sign or e-sign and date it. California adds its own items. Aetna's state supplement says "California requires that all medical record documentation include" the patient's preferred language and "an offer of a qualified interpreter and, if interpretation services are declined, the enrollee's refusal." The office manual's record audit adds, for California members only: "For pediatric members with an autism spectrum disorder diagnosis, there is documentation of collaboration, consultation and/or continuity of care."[7][4][8]
Setting-agnostic for outpatient ABA, with coordination "with existing providers and/or the school district" and tapering toward supports such as school. CPB 0648: "Many Aetna plans exclude coverage of educational services. For example, speech therapy or ABA services during class would be excluded," and GR-69017-4 asks whether hours are requested during class. On fully insured California plans, H&S § 1374.72(h) bars limiting coverage because services could be covered by "special education or an individualized education program."[4][3][15]
Services must be "provided directly or billed by" the appropriately licensed or BACB-certified provider unless a mandate, plan document or contract says otherwise; the precertification form captures the provider group TIN or PIN and network status. The national precertification list also applies to the Sutter Health | Aetna joint-venture plans in California.[4][6][5]
Not addressed in CPB 0554, CPB 0648, the ABA guide, the precertification form or the provider manuals.[4]
Ask the plan: The participating-provider agreement or a written coding determination from Aetna Behavioral Health.
Possibly, through a "nonparticipating referral" that Aetna reviews — for example when the needed clinician "isn't available in network (and the member's plan provides coverage for out-of-network services)" or the child is continuing treatment with a nonparticipating clinician. Aetna's manuals do not describe a single case agreement program by name.
Yes — for autism under Aetna’s national policy, with California’s mandate (H&S § 1374.73 / Ins. § 10144.51) on fully insured plans. Self-funded employer plans are exempt from the mandate, so verify funding type first.
Nationally yes, but Aetna’s California supplement says outpatient behavioral health on fully insured plans has not required prior authorization since March 1, 2024, without mentioning ABA. Call Aetna precertification (1-888-632-3862) for each member and keep the reference number.
No. Aetna Better Health of California stopped operating on January 1, 2024; Medi-Cal ABA runs through the county Medi-Cal plan.
Aetna publishes no such requirement for ABA. A referral has to accompany a claim only when the member’s plan requires PCP referrals for specialist care. Behavioral health is a direct-access benefit in Aetna’s behavioral health manual.
