# Aetna ABA coverage in Iowa: the intake guide.

_Payer Guide · Aetna · Iowa · Last updated September 2026 · 9 primary sources_

> Aetna national ABA guide + CPB 0554, layered on Iowa's mandate (no age or dollar caps from 1/1/2026).

For an intake team in Iowa, an Aetna card means three layers at once: Aetna's national ABA criteria, Iowa's autism mandate (Iowa Code § 514C.31 for large-group and public-employee plans), and the plan's funding type, which decides whether the mandate applies at all. Aetna publishes no Iowa-specific ABA document, so the national criteria plus the mandate are the whole written picture.

## Prior authorization and diagnosis at a glance

- **Prior auth for the assessment**: Required — Aetna's behavioral health precertification list (eff. 8/1/2024) includes ABA codes 97151–97158, 0362T and 0373T [2]
- **Prior auth for treatment**: Required — precertification for 97151–97158, 0362T and 0373T; "To get ABA services precertified, call the number on the member's Aetna ID card" [2][4]
- **Autism diagnosis required?**: Yes — a DSM-5 ASD diagnosis (ICD-10 F84.0, F84.3–F84.9) by an appropriate provider [1]

## At a glance

- **Covers ABA?:** Yes — for ASD, per Aetna's national ABA criteria
- **State mandate:** Iowa Code § 514C.31 (large group, more than 50 FTEs, and non-state public employers) and § 514C.28 (State of Iowa employee plan)
- **Mandate age:** No age limit for plans issued or renewed on/after 1/1/2026 (H.F. 330 struck under-19 and under-21 limits)
- **Mandate caps:** None since 1/1/2026: H.F. 330 struck the $36,000/$25,000/$12,500 age-banded ABA maximums; no visit limits; § 514C.22 bars annual/lifetime limits on ASD benefits
- **Exempt from mandate:** Individual and small-group (50 or fewer FTEs) plans are outside § 514C.31; self-funded ERISA plans (preempted)
- **Licensure:** Licensed behavior analyst / assistant behavior analyst under Iowa Code ch. 154D (Board of Behavioral Health Professionals)

## The national criteria, applied in Iowa

Aetna's ABA Medical Necessity Guide requires "a DSM-V diagnosis of Autism Spectrum Disorder (ICD-10: F84.0; F84.3 - F84.9) obtained by an appropriate provider," services "provided directly or billed by the appropriately licensed provider," and "demonstration of functional impairment on a standardized scale of functioning in the past 12 months" such as the VABS-3, ABAS, VB-MAPP or ABLLS, at least one standard deviation below the mean or a significant risk of harm. The level of impairment must justify the hours requested. As a typical shape, comprehensive ABA runs 10–25 hours a week for children 0–7 years over one to two years; focused ABA is for "All ages" at 1–20 hours a week. Every ABA code, assessment included, is on Aetna's behavioral health precertification list. [1][3][2]

## The Iowa mandate after H.F. 330

Iowa Code § 514C.31 requires large-group plans (employers with more than 50 full-time-equivalent employees) and non-state public-employee plans to cover ABA "provided by a practitioner to covered individuals for the treatment of autism spectrum disorder pursuant to a treatment plan"; § 514C.28 does the same for the State of Iowa employee plan. For plans issued or renewed on or after January 1, 2026, H.F. 330 removed the old age limits (under 19; under 21) and dollar caps ($36,000 / $25,000 / $12,500 by age band; $36,000 for state employees) and added a bar on annual or lifetime limits for autism benefits (§ 514C.22). Cost sharing and "prior authorization and prior approval" are still allowed. Reviews of the treatment plan are limited to once every three months in the first year and every six months after, at the plan's cost. Individual, small-group and self-funded plans are outside the ABA mandate. [5][6][10][7]

## Licensure and rates in Iowa

Iowa licenses behavior analysts under Iowa Code chapter 154D on proof of current BACB (or other accredited) certification; assistant analysts also need ongoing supervision by a licensed behavior analyst, and technicians are exempt paraprofessionals working under a licensed analyst's direction. Iowa is a licensure state, so Aetna's clause that services be "provided directly or billed by licensed behavior analysts (in states with behavior analyst licensure laws)" points at the Iowa LBA. Aetna does not publish commercial ABA rates; they are negotiated in your participation agreement. For a benchmark, Iowa Medicaid pays $28.59 per 15 minutes for 97153 by a BCBA and $17.16 by a technician. [8][11]

## Intake gates

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

- **Diagnosis recency**: Twelve months, on the functional measure rather than the diagnosis: "There is demonstration of functional impairment on a standardized scale of functioning in the past 12 months." The ASD diagnosis itself has no stated shelf life. [1]
- **Who may diagnose**: An "appropriate provider (i.e. licensed psychologist/psychiatrist, physician or other health care professional qualified to diagnose mental health conditions within their scope of practice)." F84.2 (Rett syndrome) is outside the listed codes. [1]
- **Diagnostic tools required**: Adaptive-functioning instruments, not autism diagnostic instruments: "the Vineland Adaptive Behavior Scales 3 (VABS-3), the Adaptive Behavior Assessment Scale (ABAS), VB-MAPP or ABLLS," with impairment at least one standard deviation below the mean. No ADOS-2 or ADI-R requirement appears. [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." Many self-funded plans use "Maintenance of Benefits (MOB)" rather than the "100% Allowable" method, so a secondary payment can be smaller. Iowa's COB rule governs fully insured plans: for a child of married or cohabiting parents, "the plan of the parent whose birthday falls earlier in the calendar year is the primary plan." With Medicaid, Aetna pays first (42 CFR 433.139); TRICARE pays after ("TRICARE last pay," 32 CFR 199.8); "CHAMPVA is the last payer to OHI" (38 CFR 17.276(d)). [4][13][14][15][16]
- **Age limit** _(plan-dependent)_: Aetna sets no upper age limit: comprehensive ABA is typically for ages 0–7, focused ABA for "All ages." The legal layer: plans subject to § 514C.31 or § 514C.28 that were issued or renewed on or after 1/1/2026 have no mandate age limit; plans renewed earlier keep the old limits (under 19; under 21) until renewal; individual, small-group and self-funded plans follow their plan documents. [1][5][7]
  - Ask the plan: Aetna precertification: confirm funding type, group size and renewal date.
- **Referral required?** _(plan-dependent)_: Aetna states no referral requirement. Where Iowa's mandate applies, the ABA must follow a treatment plan developed by a licensed physician or licensed psychologist after a comprehensive evaluation (§ 514C.31). [1][5]
  - Ask the plan: Aetna precertification and the member's benefit document.
- **Prior-auth decision time** _(plan-dependent)_: Aetna publishes no commercial decision clock of its own ("To get ABA services precertified, call the number on the member's Aetna ID card"). The legal clock depends on funding. Fully insured Iowa plans follow Iowa Code 514F.8: 48 hours urgent, 10 calendar days non-urgent, 15 days for complex cases, a receipt within 24 hours, and an approval valid for at least 90 days. Self-funded ERISA plans: a pre-service decision "not later than 15 days after receipt of the claim" (one 15-day extension), 72 hours urgent, and 24 hours for an urgent request to extend treatment made "at least 24 hours prior to the expiration." [4][9][12]
  - Ask the plan: Aetna precertification: ask whether the plan is fully insured or self-funded, and how far ahead Aetna wants the reauthorization.
- **Telehealth** _(ask the plan)_: Not published in Aetna's ABA materials.
  - Ask the plan: Aetna provider services and the member's benefit document: which ABA codes pay by telehealth, and with which POS code.

## Delivery and billing rules

Coverage decides whether Aetna in Iowa 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**: 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 guide publishes no percentage or caseload cap. In Iowa, technicians practice only "under the extended authority and direction of a licensed behavior analyst or licensed assistant behavior analyst" (Iowa Code 154D.4). [1][8]
- **Bill as provider**: "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." Iowa is a licensure state (chapter 154D), so the licensed behavior analyst is who this clause points at. [1][8]
- **Place of service** _(plan-dependent)_: Aetna publishes no ABA place-of-service list. The one boundary it states: "Aetna is not required 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." Iowa's mandate likewise does not affect IEP or IFSP obligations (§ 514C.31). Whether ABA is payable in a school, the community or a group home is a benefit-document question. [1][5]
  - Ask the plan: The member's benefit document and Aetna provider services.
- **Concurrent billing (97153 + 97155)** _(ask the plan)_: Not published. Neither the ABA Medical Necessity Guide nor CPB 0554 says whether 97153 and 97155 pay for the same clock time.
  - Ask the plan: Aetna provider services at the number on the member ID card, and your participation agreement's reimbursement terms.
- **Daily limits / MUEs** _(ask the plan)_: Not published. Aetna's ABA documents set criteria and precertification but no per-day unit ceiling. Where Iowa's mandate applies (plans issued or renewed from 1/1/2026), visit limits and dollar caps on ABA are barred. [5]
  - Ask the plan: The Aetna precertification approval, which states the authorized units.
- **Session-note signature** _(ask the plan)_: Not published in Aetna's ABA materials.
  - Ask the plan: The Aetna provider manual and your participation agreement's documentation clause.

## What intake should collect for Aetna in Iowa

- **Plan funding and group size:** Large group or public employer: the Iowa mandate applies. Individual, small group or self-funded: the plan document decides.
- **Plan renewal date:** No age or dollar caps apply to plans issued or renewed on or after 1/1/2026.
- **Adaptive measure within 12 months:** Aetna wants a standardized functioning score (VABS-3, ABAS, VB-MAPP or ABLLS) from the past 12 months.
- **Diagnosis report:** DSM-5 ASD diagnosis, diagnosing provider and credentials, and the evaluation date.

## Common questions

### Does Aetna cover ABA therapy in Iowa?

Yes, for autism under Aetna's national criteria, with precertification for every ABA code. Large-group and public-employee plans must cover ABA under Iowa Code § 514C.31 or § 514C.28; individual, small-group and self-funded plans follow their plan documents.

### Does the Iowa autism mandate cap ABA hours or dollars?

Not for plans issued or renewed on or after January 1, 2026: H.F. 330 removed the age limits and the age-banded dollar maximums, and visit limits were already barred. Medical necessity still sets the hours.

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

Commercial rates are negotiated in your participation agreement and not published. Iowa Medicaid's fee schedule ($28.59 per 15 minutes for 97153 by a BCBA; $17.16 by a technician) is a public benchmark.
