# Aetna ABA coverage in Missouri: the intake guide.

_Payer Guide · Aetna · Missouri · Last updated September 2026 · 7 primary sources_

> CPB 0554 (ABA) + CPB 0648 (ASD) + the RSMo § 376.1224 mandate layer.

For an intake team in Missouri, a Aetna card means three layers at once: the carrier's national clinical policy, Missouri's autism insurance mandate (RSMo § 376.1224), and the plan's funding type deciding which of the two actually binds. This guide stacks them in order.

## Prior authorization and diagnosis at a glance

- **Prior auth for the assessment**: Required — precertification (form GR-69017-4), per Aetna's behavioral health precertification list (eff. 8/1/2024) — CPB 0554 itself sets no precertification rule [5][6]
- **Prior auth for treatment**: Required — precertification; reauthorization commonly ~6 months (verify per plan) [5][6]

## At a glance

- **Covers ABA?:** Yes — for ASD, per the national Aetna policy
- **State mandate:** RSMo § 376.1224 (HB 1311, 2010; expanded 1/1/2020)
- **Mandate age:** No overall age limit stated; the ABA dollar cap applies through age 18
- **Mandate caps:** $40,000/yr ABA (statutory base, CPI-indexed; exceedable with plan approval)
- **Exempt from mandate:** Self-funded private ERISA plans; short-term and limited policies
- **Licensure:** MO Licensed Behavior Analyst (RSMo 337.315, Div. of Professional Registration)

## The national policy, applied in Missouri

Aetna covers ABA for autism spectrum disorder under its national clinical policy CPB 0554 (paired with CPB 0648 for ASD), and considers ABA experimental for anything else. Precertification is required for both the assessment and treatment — form GR-69017-4, submitted via Availity or phone — with reauthorization commonly on a roughly 6-month cadence. Aetna publishes no Missouri-specific ABA policy, form, or supplement — we checked — so the national policy plus the state mandate is the whole picture, with Missouri's statutory constraints (the 6-month treatment-plan review cadence, the ABA cap) applying to fully-insured business by operation of law rather than via a carrier document. Plan funding type is therefore the first fact to establish on every benefits check. The full national policy breakdown lives in our Aetna guide; this page covers what changes in Missouri. [1][2]

## The Missouri mandate: what it guarantees (and doesn't)

Missouri's mandate — enacted by 2010's HB 1311, with the current version applying to plans delivered, issued, continued, or renewed on or after January 1, 2020 (which added developmental and physical disability coverage) — reaches unusually far: beyond ordinary individual and group policies, it covers the state consolidated health care plan, self-insured governmental plans, MEWAs, and self-insured school district health plans established after 1/1/2020. ABA must be ordered by the treating licensed physician or psychologist in a treatment plan, supervised by a board-certified behavior analyst licensed under Chapter 337, and insurers may review the ABA treatment plan no more than once every 6 months unless the provider agrees otherwise. The headline number: ABA carries a $40,000-per-calendar-year cap for individuals through age 18 — statutory base value. Three things soften it: the cap may be exceeded with prior plan approval when additional ABA is medically necessary; it is CPI-indexed (carriers must adjust at least triennially, with the current adjusted figure published annually in the Missouri Register — don't quote $40K as the live number without checking); and other autism treatments (OT/PT/speech, psychiatric, pharmacy) sit outside the cap entirely. Self-funded private ERISA plans remain federally preempted. [3]

## Licensure & rates in Missouri

Missouri requires behavior-analyst licensure: RSMo 337.315 prohibits practicing applied behavior analysis without an LBA (or Licensed Assistant Behavior Analyst) license or an enumerated exception — supervised trainees, licensed psychologists within scope, IDEA school personnel, and students among them. The Behavior Analyst Advisory Board within the State Committee of Psychologists (Division of Professional Registration, RSMo 337.300–337.345) reviews applications, and the mandate itself requires BCBA-supervised, Chapter 337-licensed delivery — so licensure is a coverage requirement, not just a credentialing one. On rates: Aetna does not publish commercial ABA fee schedules for Missouri (none of the national carriers do) — rates are contract-negotiated and live in your participating-provider agreement. Benchmark against MO HealthNet's published fee schedule ($20.13/unit on 97153 at the analyst tier) when modeling. [4]

## Intake gates

The questions that decide whether a family can start with Aetna in Missouri, and what they have to bring.

- **Who may diagnose**: Two lists, and the narrower one is the statute's. Aetna requires the diagnosis to come from a provider qualified to diagnose within their scope — a licensed psychologist, psychiatrist or physician — and its precertification form (GR-69017-4, eff. 1/1/2026) asks for the DSM-5 diagnosis code, the diagnosing provider and their credentials. On a plan the Missouri mandate reaches, the ABA itself must additionally be ordered by the treating licensed physician or psychologist, so a diagnosis from a nurse practitioner will not by itself satisfy the ordering requirement. [1][2][3]
- **Telehealth**: Aetna covers telehealth for 97151, 97153, 97155, 97156 and 97157 — 97152 is excluded — billed with GT, 95 or FR modifiers per its telemedicine payment policy. Treat the answer as perishable: Aetna announced it would end ABA telehealth coverage in late 2023 and rescinded the change within weeks. Missouri's Medicaid telemedicine rule, which expressly allows technician-delivered ABA by telemedicine, is a different program and does not bind a commercial Aetna plan. [1]
- **Other insurance (who pays first)**: Aetna: "We coordinate benefits as allowed by state or federal law following the National Associations of Insurance Commissioners (NAIC) guidelines. If there is no applicable law, then we coordinate according to the member's plan" — the manual's order-of-benefits list includes the birthday rule for children whose parents are not separated or divorced. Missouri's COB rule (20 CSR 400-2.030) governs fully insured group plans: when parents are not separated or divorced, "The benefits of the plan of the parent whose birthday falls earlier in a year are determined before those of the plan of the parent whose birthday falls later in that year" (same birthday: the plan that covered the parent longer); for divorced or separated parents a court decree naming the responsible parent controls. Self-funded plans follow their plan document instead, and Aetna notes many use "Maintenance of Benefits (MOB)" rather than the "100% Allowable" method most state laws require, so a secondary payment can be smaller. If the child also has Medicaid, this plan pays first: Medicaid is payer of last resort (42 CFR 433.139) — bill here, then send the EOB or denial to Medicaid, and get Medicaid's own prior auth too if the state requires it. TRICARE is secondary to this plan ("TRICARE shall be last pay," 32 CFR 199.8), and "CHAMPVA is the last payer to OHI" (38 CFR 17.276(d)). [8][12][13][14][15]
- **Age limit** _(plan-dependent)_: The mandate sets no overall age limit on autism coverage — what it ages out is the dollar cap. RSMo § 376.1224 subjects ABA to “a maximum benefit of forty thousand dollars per calendar year for individuals through eighteen years of age,” a statutory base that is CPI-indexed (the Department of Commerce and Insurance publishes the adjusted figure annually). Coverage required under the section other than ABA “shall not be subject to the age and dollar limitations described in this subsection,” so OT, PT, speech, psychiatric and pharmacy care for autism carry no age cut-off and no dollar cap. Self-funded private ERISA plans are preempted from all of it; note Missouri's unusual reach into the state consolidated health care plan, self-insured governmental plans, MEWAs and self-insured school-district plans established on or after 1/1/2020. [3]
  - Ask the plan: Benefits verification on the specific plan, via the payer portal or the number on the member’s card — ask whether RSMo § 376.1224 reaches this plan (it reaches fully-insured plans, the state consolidated health care plan, self-insured governmental plans, MEWAs and self-insured school-district plans established on or after 1/1/2020, but not private self-funded ERISA plans), and what the plan applies as this year’s dollar cap. The Missouri Department of Commerce and Insurance publishes the CPI-adjusted figure annually — quote that year’s number, never the $40,000 statutory base.
- **Referral required?** _(plan-dependent)_: Yes on a plan the mandate reaches, and the statute is specific about who writes it: ABA “must be ordered by the treating licensed physician or psychologist” in a treatment plan, and must be supervised by a board-certified behavior analyst licensed under chapter 337. Capture the ordering physician or psychologist and the treatment plan they signed. Two Missouri rules work in the provider's favour once the order exists: the carrier may review the treatment plan no more than once every six months unless the provider agrees otherwise, and the cost of obtaining any review or treatment plan is borne by the plan. Self-funded private ERISA plans are outside the statute. [3]
  - Ask the plan: Benefits verification on the specific plan, via the payer portal or the number on the member’s card — confirm first whether RSMo § 376.1224 reaches this plan. Where it does, capture the ordering licensed physician or psychologist and the treatment plan they signed, and the supervising chapter 337 licensed behavior analyst. Where it does not (a private self-funded ERISA plan), ask the carrier whether it requires a physician or psychologist order and in what form.
- **Prior-auth decision time** _(plan-dependent)_: Aetna publishes no commercial decision clock of its own: ABA "services require prior authorization. To get ABA services precertified, call the number on the member's Aetna ID card," and the manual sets no reauthorization lead time (none in the ABA Medical Necessity Guide or the ABA precert form either). The legal ceiling depends on funding. Missouri fully insured plans are bound by RSMo 376.1363: a carrier "shall make the determination within thirty-six hours, which shall include one working day, of obtaining all necessary information," with an approval phoned or sent electronically to the provider within 24 hours; concurrent review (continuing an approved course) is decided "within one working day of obtaining all necessary information." The clock starts when the file is complete, not when the form lands. Self-funded ERISA plans are outside state law and follow 29 CFR 2560.503-1: a pre-service decision "not later than 15 days after receipt of the claim" (one 15-day extension), 72 hours for urgent care, and an urgent extension request decided within 24 hours if made at least 24 hours before the approval expires. Aetna's Missouri supplement adds the peer-to-peer window for fully insured members: request "within 14 calendar days of the denial letter date"; response "within one 24-hour working day of the request." [8][9][10][11]
  - Ask the plan: Aetna precertification (number on the member ID card): ask whether the plan is fully insured or self-funded (which sets the legal clock) and how far before expiry Aetna wants the ABA reauthorization — Aetna publishes no lead time.
- **Diagnosis recency** _(ask the plan)_: Aetna publishes no recency rule for the ASD diagnostic evaluation, and § 376.1224 sets none either — its six-month clock runs on plan review of the treatment plan, not on the age of the diagnosis. Capture the evaluation date anyway: the precertification package asks for it. [1][3]
  - Ask the plan: The precertification call or Availity, when submitting form GR-69017-4 — ask whether an evaluation of this age will be accepted for this plan.
- **Diagnostic tools required** _(ask the plan)_: No instrument is named at either level. CPB 0554 does not require or reference a specific diagnostic tool, and the precertification form asks for the diagnosis code, the diagnosing provider and their credentials rather than for an instrument and score; § 376.1224 names none either. [1][3]
  - Ask the plan: Aetna precertification (Availity or the number on the card) — ask whether a specific instrument is expected for this plan before scheduling testing.

## Delivery and billing rules

Coverage decides whether Aetna in Missouri pays. These decide whether the claim survives: staffing and supervision, concurrent billing, per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.

- **Supervision**: Practitioners delivering ABA under CPB 0554 need BACB national certification or state behavior-analyst licensure, with unlicensed staff working under supervision per practice standards; Aetna publishes no numeric ratio. Missouri makes licensure a coverage requirement rather than just a credentialing one: § 376.1224 requires ABA to be supervised by a board-certified behavior analyst licensed under chapter 337, and RSMo 337.315 prohibits practising applied behavior analysis without an LBA or LaBA licence outside enumerated exceptions. [1][2][3][4]
- **Bill as provider** _(plan-dependent)_: Aetna does not publish the rendering-versus-billing NPI convention for ABA. Missouri's mandate does supply one half of the answer for plans it reaches: reimbursement is directed to the autism service provider, or to the entity or group the supervising board-certified behavior analyst works for, and it expressly includes line-therapist services delivered under that supervision when they are in the treatment plan and medically necessary. [3][1]
  - Ask the plan: Aetna provider services or Availity — confirm the rendering-versus-billing NPI convention and any required degree-level modifiers before the first claim.
- **Concurrent billing (97153 + 97155)** _(ask the plan)_: Not published. Neither CPB 0554 nor CPB 0648 states whether 97155 and 97153 may be billed for the same clock time, and Aetna publishes no Missouri-specific ABA policy, form or supplement. [1]
  - Ask the plan: Availity Essentials for the plan's reimbursement and claim-editing policies, or the provider-services number on the member's card.
- **Daily limits / MUEs** _(ask the plan)_: Not published. CPB 0554 lists the covered ABA codes but sets no per-day unit ceiling, and Aetna publishes no ABA-specific MUE table. The operative ceiling is the precertification itself, which requires requested hours to be listed code by code — so the authorization, not a policy, is what bounds the day. CPB 0648 references intensive-intervention research norms of 25 hours a week, 12 months a year as clinical context rather than as a limit. [1]
  - Ask the plan: The authorization letter itself, plus Availity Essentials for the plan's claim-editing and reimbursement policies. Ask whether CMS MUE limits are applied to ABA codes on this plan.
- **Session-note signature** _(ask the plan)_: Not published. CPB 0554 and CPB 0648 set coverage criteria and precertification content; neither states what a session note must contain, who signs it, or by when. [1]
  - Ask the plan: Aetna provider services or Availity — ask for the documentation standard applied at audit, and keep to the precertification form's own data elements in the meantime.
- **Place of service** _(ask the plan)_: Not published as a payable-settings list. What CPB 0554 does make a submission requirement is adjacent and useful: the precertification form asks for concurrent services — PT, OT, speech and school services — plus how care is coordinated across them, so the school picture is data Aetna collects even though it publishes no school-versus-home rule. [1]
  - Ask the plan: Benefits verification on the specific plan — ask which places of service are payable for ABA and whether school-based delivery is excluded.

## What intake should collect for Aetna in Missouri

- **Plan funding type:** Fully insured (mandate applies — including MO's unusual reach into governmental and school self-insured plans) vs. self-funded private ERISA (exempt). Ask for the employer and check the card.
- **Member ID + card photo:** Enough to run a live benefits verification — the only reliable answer on limits and cost-sharing.
- **Diagnosis report:** DSM-5 ASD diagnosis, diagnosing provider and credentials, evaluation date.
- **Age vs. the cap:** The ABA dollar cap runs through age 18 and is CPI-indexed — verify the current adjusted value and year-to-date usage before projecting hours.

### EDI routing

- **Payer ID (pVerify):** 00001
- **Payer ID (Availity):** 60054 — 60054 is Aetna's long-standing national payer ID, confirmed present in the fetched Availity list — but that list carries an "As of 08/08/2012" footer, so this ships 'inferred' pending reconfirmation against a current export (same treatment as aetna-florida / aetna-georgia).
- **Supports 270/271 eligibility:** Yes

### Code-level coverage

Code notes:

- **97151, 97152, 97153, 97154, 97155, 97156, 97157, 97158, 0362T, 0373T:** Verify via: Aetna provider services / precertification — CPB 0554 & 0648 are medical-necessity policies only; no ABA coding/reimbursement policy could be located. Missouri mandate (RSMo 376.1224): fully-insured plans carry a $40,000/calendar-year ABA cap through age 18 (CPI-indexed statutory base, exceedable with plan approval); self-funded private ERISA plans are exempt. The cap is a benefit-design fact, not a per-code rule — verify plan funding type and the current adjusted cap on the live 271/benefits check.

### Contacts

- **Provider services phone:** 1-800-624-0756 (HMO-based & Aetna Medicare Advantage plans) or 1-888-632-3862 / 1-888-MD-AETNA (all other plans) — Aetna Provider Service Center; self-service options include verifying patient coverage/benefits and getting medical precertification information. Behavioral-health-specific provider services routes to the number on the member's ID card — no separate universal BH/ABA line is published.
- **Portal:** [Availity (Aetna Payer Space)](https://www.availity.com/aetnaproviders)

Questions to ask on a verification call:

- Is ABA billed on Aetna's standard medical payer ID, or does a separate behavioral-health administrator/payer ID handle ABA claims for this member's plan?
- Does this group support real-time (vs. batch) 270/271 eligibility responses?
- What is the ABA precertification process and form for this plan, and what are the daily/session unit caps per code (97151-97158, 0362T, 0373T)?
- Which places of service (home, school, clinic, telehealth) are approved for this member's ABA benefit, and what billing modifiers are required for out-of-clinic delivery?
- Is this a fully-insured Missouri plan subject to the RSMo 376.1224 $40,000/year ABA cap, or a self-funded ERISA plan exempt from the state mandate — and if capped, what is the current adjusted annual maximum?

## Common questions

### Does Aetna cover ABA therapy in Missouri?

Yes — under the carrier's national policy for ASD, layered on Missouri's mandate (RSMo § 376.1224) for fully-insured plans. Self-funded private employer plans are exempt from the mandate, so always verify plan funding type first.

### What does the Missouri autism mandate require?

Coverage of ASD diagnosis and treatment including ABA, with a $40,000-per-year ABA cap through age 18 — a CPI-indexed statutory base that can be exceeded with plan approval when medically necessary. Treatment-plan reviews are limited to once every 6 months, and ABA must be supervised by a Chapter 337-licensed behavior analyst.

### What does Aetna pay for ABA in Missouri?

Commercial ABA rates are not published — they are negotiated in your participating-provider agreement. Benchmark against the MO HealthNet fee schedule, and treat rate-setting as part of contracting.
