# Aetna ABA coverage in Idaho: the intake guide.

_Payer Guide · Aetna · Idaho · Last updated October 2026 · 13 primary sources_

> Aetna’s national ABA guide + precert list, on top of Idaho’s Bulletin 18-02 in place of an autism statute.

For an Idaho intake team, an Aetna card means Aetna’s national ABA rules on top of Idaho’s unusual legal floor. Idaho has no autism statute, only Department of Insurance Bulletin 18-02, and the plan’s funding type decides whether even that applies. Aetna publishes no Idaho-specific ABA document, so the national guide plus the bulletin is the whole picture.

## Prior authorization and diagnosis at a glance

- **Prior auth for the assessment**: Required — Aetna’s behavioral health precertification list names ABA codes 97151, 97152, 97153, 97154, 97155, 97156, 97157, 97158, 0362T and 0373T [2]
- **Prior auth for treatment** _(plan-dependent)_: Required — precertification per the same list; progress re-evaluated every six months (reauthorization interval set per plan) [2][1]
  - Ask the plan: Availity or the precertification number on the member card — confirm ABA precertification and the authorization span for this plan; self-funded plans may carve behavioral health out.
- **Autism diagnosis required?**: Yes — DSM-5 ASD (ICD-10 F84.0; F84.3–F84.9) obtained by an appropriate provider [1]

## At a glance

- **Covers ABA?:** Yes, for ASD per Aetna’s national ABA medical necessity guide
- **State mandate:** No autism statute — Idaho DOI Bulletin No. 18-02 (2018) requires ASD treatment on state-regulated plans that cover rehabilitative or habilitative services (plan years from 1/1/2019)
- **Mandate age:** None — the bulletin sets no age limit
- **Mandate caps:** None separate — no separate dollar or visit limits; cost-sharing in parity with other mental health and med/surg benefits
- **Exempt from mandate:** Self-funded employer (ERISA) plans Idaho does not regulate; plans with no rehabilitative/habilitative benefit fall outside the bulletin’s trigger
- **Licensure:** None — Idaho has no behavior-analyst licensure law; BACB certification governs

## The national policy, applied in Idaho

Aetna’s precertification list for participating behavioral health providers (effective August 1, 2024) names every ABA code: 97151, 97152, 97153, 97154, 97155, 97156, 97157, 97158, 0362T and 0373T. Requests go through Availity. The ABA medical necessity guide requires a DSM-5 ASD diagnosis (F84.0; F84.3–F84.9) "obtained by an appropriate provider," services "provided directly or billed by the appropriately licensed provider," and "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. Progress is evaluated every six months. The guide describes comprehensive ABA as typically 10–25 hours a week for ages 0–7 and focused ABA as 1–20 hours a week at all ages. These are typical figures, not caps. Neither document carries an Idaho exhibit (the guide’s only state exhibit is for Maryland). [2][1][3]

## The Idaho coverage floor: Bulletin 18-02, not a statute

Idaho is one of the few states with no autism insurance statute, and intake should say so plainly. What Idaho has instead is Department of Insurance Bulletin No. 18-02 (April 2, 2018). Reading the federal Mental Health Parity and Addiction Equity Act, ACA § 1557 and the state’s Essential Health Benefits together, the Department declared that it "will consider an exclusion of treatments for autism spectrum disorder as discriminatory and prohibited when a plan includes coverage of rehabilitative or habilitative services, such as coverage of occupational therapy or speech therapy." It applies to the individual, small-group and large-group insured markets, and to self-funded plans subject to Idaho Code title 41, chapters 40 or 41, for plan years starting on or after January 1, 2019. Covered treatment must be "consistent with other mental health services (including applicable deductibles, copayments, or coinsurance), not subject to any separate dollar limits or visit limits, and in parity with medical and surgical benefits." The bulletin defines treatment as "evidence-based care and related equipment prescribed or ordered for an individual diagnosed with an autism spectrum disorder by a licensed physician or a licensed psychologist who determines the care to be medically necessary, including but not limited to behavioral health treatment" — it does not name ABA by name, and it sets no age limit. Carriers may still review medical necessity and "periodically review the medical necessity of continuing" treatment. Two practical limits: a bulletin is weaker than a statute, and a self-funded employer plan the Department does not regulate (most ERISA plans) sits outside it entirely — plan funding type is the first fact to establish. [5]

## Licensure & rates in Idaho

Aetna’s guide requires services to be provided or billed by "licensed behavior analysts (in states with behavior analyst licensure laws), board-certified behavior analysts, or licensed psychologists." Idaho has no licensure law and is not on the BACB’s list, so in Idaho the BCBA credential is what qualifies. Aetna publishes no commercial ABA rates, and they are negotiated in your agreement. [1][6]

## Claims: filing deadline and disputes

Aetna’s national provider manual (edition 6/26) publishes no numeric filing limit: it defines a clean claim as one “received in a timely manner,” so the operative deadline is the one in your Aetna agreement. Claim disputes go through Availity — the claim must be in Finalized status, then “Dispute Claim” from the Claim Status transaction — and Aetna runs one level of provider appeal for payment decisions; medical-necessity appeals go through the member appeal process. [13]

On the claim mechanics the same manual says a clean claim "Doesn’t involve coordination of benefits," and that COB, corrected and voided claims can all be submitted through Availity at no charge; it sets no separate deadline for corrected or secondary claims and publishes no weekly payment cycle or submission cutoff. [13]

## How fast must Aetna pay a clean claim in Idaho?

Idaho’s prompt-pay clock depends on how fast the provider files. Under Idaho Code § 41-5602, if an electronic claim is submitted within thirty days of the date of service, the insurer “shall pay or deny the claim not later than thirty (30) days after receipt”; a paper claim submitted within forty-five days of service must be paid or denied within forty-five days. A denial or request for more information must be sent in writing within the same thirty or forty-five days and must describe everything needed, after which the insurer has thirty days from receiving it. Late claims accrue interest at the statutory contract rate (§ 41-5603). The time limits do not apply where the insurer is complying with a provider contract that sets different payment terms (§ 41-5605(3)). These statutes bind fully insured plans issued in the state; a self-funded employer plan (ERISA) is not subject to them and follows its plan documents and your contract. [10][11][12]

## Does Aetna need a referring provider on the ABA claim?

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).” [13][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. [13][14]

## What goes in an Aetna ABA precertification request?

Since August 1, 2026, one Aetna form — “Outpatient Behavioral Health (BH) – ABA Treatment Request: Required Information for Precertification” (GR-69017-4) — “replaces all other” ABA precertification information forms. It does not start a request. Start the request on Availity (Authorization Add) or by phone, then attach the form and the records to the case, or fax them to FaxHub 833-596-0339 with the reference number. [15]

Section 1 asks for the member and provider group details; the current DSM-5 diagnosis code(s); the diagnosing provider’s name and credentials; hours per authorization period for the assessment codes 97151, 97152 and 0362T; hours per week for 97153–97158 and 0373T; and whether any hours fall during class. Section 2 asks who supervises the ABA services, and whether the child also gets PT, OT, speech, mental health or school services and whether you coordinate with those providers. It also asks for current impairment areas with supporting severity data. [15]

Attach the results of a standardized assessment (“i.e. Vineland, ABAS, VB-MAPP”) completed within the past 12 months. Also attach a time-limited, individualized treatment plan with baselines and measurable progress criteria, caregiver goals, titration and discharge criteria with an aftercare plan, and baseline, interim and current data for every goal. The form names CPB 0648 and the ABA Medical Necessity Guide as the review criteria. [15]

## What must an Aetna ABA reauthorization request contain, and are graphs required?

Aetna’s ABA medical necessity guide (©2026) says "A member's progress is to be evaluated every six months," and a member not making progress "will be transitioned to other appropriate services"; coverage ends when medical necessity is no longer met or when standardized improvement thresholds (for example, two or more standard deviations in multiple domains) are reached. The guide does not specify a graph or data-presentation format for the reassessment; send the updated treatment plan with measurable progress against each goal and the standardized scores the termination criteria are tested against. [1]

## Intake gates

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

- **Diagnosis recency**: No expiry on the diagnosis itself, but the functional evidence must be recent: "demonstration of functional impairment on a standardized scale of functioning in the past 12 months." Progress is re-evaluated every six months. [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)." [1]
- **Diagnostic tools required**: CPB 0648 names the diagnostic instruments used alongside clinical assessment: ADI-R, ADOS-2, CARS-2 and the Asperger Syndrome Diagnostic Scale. The ABA guide then requires a standardized functioning measure within 12 months, such as VABS-3, ABAS, VB-MAPP or ABLLS, showing impairment at least one standard deviation below the mean or significant risk of harm. [3][1]
- **Referral required?**: Aetna’s national ABA documents require precertification, not a physician referral (the guide’s prescription requirement sits in its Maryland exhibit only). For Idaho state-regulated plans, Bulletin 18-02 frames covered treatment as care "prescribed or ordered" by a licensed physician or licensed psychologist, so get a written prescription. [2][1][5]
- **Telehealth**: 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. [4]
  - Ask the plan: Aetna provider services or Availity — confirm the payment policy is still current and that the member's plan carries a telehealth benefit before scheduling remote hours.
- **Age limit** _(plan-dependent)_: Aetna’s guide sets no age cap. Its intensity table describes comprehensive ABA as typical for ages 0–7 and focused ABA for all ages. Bulletin 18-02 sets no age limit for state-regulated plans, and self-funded plans may carry their own age terms. [1][5]
  - Ask the plan: Benefits verification on the member ID — establish fully insured vs. self-funded, then the plan’s age terms.
- **Prior-auth decision time** _(plan-dependent)_: Turns on how the plan is funded. Idaho’s Managed Care Reform Act requires a managed care organization to answer a nonemergency prior-authorization request "within two (2) business days after complete member medical information is provided," "unless exceptional circumstances warrant a longer period," and makes an obtained approval final after the service is delivered except for fraud, nonpayment or loss of eligibility (Idaho Code § 41-3930). Self-funded ERISA plans follow 29 CFR 2560.503-1: 15 days, one 15-day extension, and 72 hours for urgent claims. [7][8]
  - Ask the plan: At benefits verification ask whether the plan is fully insured or self-funded, then confirm Aetna’s precertification turnaround and continuation lead time via Availity.
- **Other insurance (who pays first)** _(plan-dependent)_: For a child on two parents’ plans, Idaho’s rule (IDAPA 18.04.14.022) makes "the plan of the parent whose birthday falls earlier in the calendar year" primary, with separate rules for divorced or separated parents. Self-funded plans follow their own documents. If the child also has Idaho Medicaid, this plan pays first because Medicaid is the payer of last resort. Get Aetna’s precertification anyway, and note that Medicaid pays CHIS on H-codes. TRICARE pays after this plan (10 U.S.C. 1079(i)(1)), and CHAMPVA is the last payer (38 CFR 17.270). [9][16][17][18]
  - Ask the plan: Ask Aetna at benefits verification for the coordination-of-benefits order on file, and record every other coverage the child has.

## Delivery and billing rules

Coverage decides whether Aetna in Idaho 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**: Services must be provided directly or billed by licensed behavior analysts (in licensure states), board-certified behavior analysts, or licensed psychologists with behavior analysis in scope, unless state mandates, plan documents or contracts require otherwise. Where they allow services by unlicensed or non-certified staff, "there must be supervision and direction of the unlicensed or non-certified providers in line with practice standards." Aetna publishes no numeric supervision ratio. [1]
- **Daily limits / MUEs**: No per-day or per-week cap. The guide gives typical intensities (comprehensive 10–25 hours a week for ages 0–7 over 1–2 years; focused 1–20 hours a week at all ages over 1–4 years), evaluates progress every six months, and ends coverage on its improvement thresholds. Bulletin 18-02 bars separate dollar or visit limits on state-regulated plans. [1][5]
- **Session-note signature**: 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. [13][1]
- **Place of service**: Outpatient ABA is setting-agnostic in the guide. In inpatient, residential or partial hospitalization settings the level-of-care criteria apply and "specific authorization for ABA is not needed in addition." The guide expects coordination with the school district and a plan that tapers toward "supports from other sources (school, as an example)." The school-setting protection in the guide is in its Maryland exhibit only. CPB 0648 notes "many Aetna plans exclude coverage of educational services." [1][3]
- **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," unless state mandates, plan documents or contracts require otherwise. Idaho has no licensure law, so the BCBA is the billing credential in Idaho. [1][6]
- **Concurrent billing (97153 + 97155)** _(ask the plan)_: Not addressed in Aetna’s ABA medical necessity guide, precertification list or CPB 0648. [1]
  - Ask the plan: Aetna provider services or the participating-provider agreement — ask for a written coding determination on 97153 and 97155 billed for the same clock time.

## What intake should collect for Aetna in Idaho

- **Plan funding type:** Fully insured (Bulletin 18-02 applies) or self-funded ERISA (outside it). Ask for the employer and check the card.
- **Member ID + card photo:** Run precertification and benefits through Availity before the assessment, because 97151 is on the precert list.
- **Diagnosis report:** DSM-5 ASD from a licensed psychologist, psychiatrist, physician or other qualified professional.
- **Standardized functioning measure within 12 months:** For example Vineland-3, ABAS, VB-MAPP or ABLLS, showing impairment at least 1 SD below the mean.
- **Prescription:** Bulletin 18-02 frames coverage around care prescribed or ordered by a licensed physician or psychologist.

## Common questions

### Does Aetna require graphs for ABA reassessments?

Aetna’s guide requires a progress evaluation every six months but does not prescribe graphs; send measurable progress against each goal and the standardized scores its termination criteria use.

### Does Aetna cover ABA therapy in Idaho?

Yes, for ASD under Aetna’s national ABA guide. On state-regulated plans Idaho’s Bulletin 18-02 also bars excluding autism treatment when the plan covers rehabilitative or habilitative services. Self-funded employer plans set their own terms.

### Does the Aetna ABA assessment need precertification?

Yes. Aetna’s behavioral health precertification list includes 97151 and 97152 along with all treatment codes.

### Does Idaho have an autism insurance mandate?

No statute. Idaho relies on DOI Bulletin 18-02 (2018): no autism exclusion where rehab or habilitative services are covered, and no separate dollar or visit limits. It sets no age limit and does not reach self-funded ERISA plans.

### Does Aetna require RBT certification for ABA technicians?

Not by name. Aetna's ABA medical necessity guide says services must be provided directly or billed by licensed behavior analysts, BCBAs or licensed psychologists "unless state mandates, plan documents or contracts require otherwise." Where those allow services by unlicensed or non-certified staff, "there must be supervision and direction" in line with practice standards. Your contract and any state licensure law decide the technician credential.

### Can the ABA assessment (97151) be done by telehealth with Aetna?

On commercial plans, yes: Aetna's telemedicine payment policy lists 97151, 97153, 97155, 97156 and 97157 with modifier GT, 95 or FR. 97152, 97154 and 97158 are listed for Medicare Advantage only. Confirm the policy is current and that the plan has a telehealth benefit.

### What is Aetna’s timely filing limit in Idaho?

Aetna’s national provider manual (6/26) does not publish a number — the filing limit is the one in your Aetna agreement.

### How fast must Aetna pay a clean ABA claim in Idaho?

Idaho law (Idaho Code § 41-5602) requires a fully insured plan to pay or deny an electronic claim within 30 days of receipt (45 for paper) — but only when the claim was filed within 30 days of the service (45 for paper), and a contract with different payment terms overrides it. Self-funded employer plans are not bound by the statute.

### Does Aetna require a referring provider (box 17) on ABA claims?

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.

### Which form does Aetna want with an ABA prior-authorization request?

Since August 1, 2026, use form GR-69017-4, “ABA Treatment Request: Required Information for Precertification.” Start the request on Availity or by phone first, then attach the completed form plus a standardized assessment from the past 12 months and the treatment plan.
