For an intake team in Colorado, a Aetna card means three layers at once: the carrier's national clinical policy, Colorado's autism insurance mandate (C.R.S. § 10-16-104(1.4)), and the plan's funding type deciding which of the two actually binds. This guide stacks them in order. Note the contrast with Colorado Medicaid: Aetna's commercial policy requires an ASD diagnosis, while Health First Colorado does not — so a family that qualifies for Medicaid ABA without a diagnosis will still need one here.
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. That clinical policy is national — what changes in Colorado is the legal floor underneath it: the state mandate below governs what fully-insured plans must cover, while self-funded employer plans answer to ERISA and federal parity instead. 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 Colorado.[1][2]
Colorado's mandate — C.R.S. § 10-16-104(1.4), originally 2009's SB 09-244 — is one of the stronger ones in our directory: it applies to all health benefit plans issued or renewed in Colorado except short-term limited-duration policies and individual grandfathered plans, carries no age limits, and carries no dollar caps — the historical $34,000/year (birth-8) and $12,000/year (9-18) ABA caps no longer appear in the current statute text, and carriers may not deny or restrict coverage because of an ASD diagnosis or utilization of mandated benefits. The statute also defines "autism services provider" with six qualification pathways reaching down to BACB Registered Behavior Technician. Self-funded ERISA plans are exempt by federal preemption, and MHPAEA parity applies on top for plans covering mental-health benefits — the caps' removal from the statute aligns the mandate with parity rather than fighting it.[3]
We checked: Aetna publishes no Colorado-specific ABA policy, form, or supplement — the national policy plus the state mandate is the whole picture. That's worth knowing in itself: it means benefits verification (plan funding type, mandate applicability, benefit limits) is where Colorado-specific answers come from, not a carrier document.[2]
Colorado currently requires no state license to practice behavior analysis — BCBA/BACB certification is the operative credential. That is changing: HB26-1425 (signed June 2, 2026) creates a Colorado Behavior Analyst Licensing Board under DORA's Division of Professions and Occupations, and on and after July 1, 2028 practicing ABA without a behavior analyst or assistant behavior analyst license becomes a class 2 misdemeanor; the law also mandates state licensure of ABA clinics. Practices should put the 2028 licensure conversion on their credentialing roadmap now. On rates: Aetna does not publish commercial ABA fee schedules for Colorado (none of the national carriers do) — rates are contract-negotiated and live in your participating-provider agreement; the Health First Colorado fee schedule (97153 at $17.20/unit for DOS 10/1/2025+) is the published in-state benchmark.[4]
The questions that decide whether a family can start with Aetna in Colorado, and what they have to bring. Each maps onto something intake should ask on the first call.
Aetna puts the recency clock on the functional assessment, not the diagnosis: medical necessity requires "demonstration of functional impairment on a standardized scale of functioning in the past 12 months," and the impairment must be at least one standard deviation below the population mean or represent a significant risk of harm to self or others. The ABA Medical Necessity Guide sets no expiry on the ASD diagnosis itself.[5]
"There is a DSM-V diagnosis of Autism Spectrum Disorder (ICD-10/ F84.0; F84.3 - F84.9) obtained by 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)." Note the code set the guide actually prints: F84.0 plus F84.3–F84.9, which leaves out F84.1 and F84.2.[5]
No diagnostic instrument is mandated; the named instruments sit on the functional-impairment test — "the Vineland Adaptive Behavior Scales 3 (VABS-3), the Adaptive Behavior Assessment Scale (ABAS), VB-MAPP or ABLLS" are given as examples of the standardized scale that must show impairment within the past 12 months.[5]
No referral or physician order is required by the national guide — the gate is the diagnosis "obtained by an appropriate provider" plus precertification. The only prescription requirement Aetna publishes is its Maryland exhibit (COMAR 31.10.39), where the child's primary care or specialty physician must perform the evaluation and prescribe the treatment with specific goals; that exhibit does not reach plans outside Maryland.[5]
Colorado's mandate carries no age limit: C.R.S. § 10-16-104(1.4) applies to all health benefit plans issued or renewed in the state except short-term limited-duration policies and individual grandfathered plans, with no age terms and no dollar caps (the cap language was struck effective 1/1/2017). The carrier's national ABA policy adds no age bound of its own, so age comes from the benefit document — and self-funded ERISA plans sit outside the mandate entirely.[3][5]
Ask the plan: Benefits verification on the specific plan — funding type first, then the ABA benefit terms.
Depends on how the plan is funded. Fully insured Colorado plans follow C.R.S. § 10-16-112.5: within five business days after receipt the carrier must say the request is "approved, denied, or incomplete" (naming the missing information), then decide within five business days after receiving it; urgent requests within "two business days but not longer than seventy-two hours." If the carrier misses those deadlines the request "is deemed granted" — but the provider must send any requested information within two business days of the notice or loses that protection. An approval "is valid for at least one hundred eighty days after the date of approval and continues for the duration of the authorized course of treatment." Self-funded (ERISA) plans follow the federal claims rule instead: pre-service decisions within 15 days of receipt (one 15-day extension), urgent within 72 hours. Aetna's office manual and ABA medical-necessity guide publish no ABA-specific decision clock.[6][7]
Ask the plan: Benefits verification: fully insured Colorado policy (5-business-day clock, 180-day approvals, deemed-granted rule) vs. self-funded ERISA plan (15 days / 72 hours).
For a child on two parents' plans, Colorado's group coordination-of-benefits regulation (fully insured plans): parents married or living together — "The plan of the parent whose birthday falls earlier in the calendar year is the primary plan" (same birthday → the plan that covered the parent longer); otherwise a court decree controls, and without one the order is custodial parent, custodial parent's spouse, non-custodial parent, then the non-custodial parent's spouse. Self-funded plans set their own order in the plan document. Aetna says it follows the NAIC order-of-benefit rules, "as allowed by state or federal law," including the birthday rule, and that many self-funded plans use maintenance of benefits. If the child also has TRICARE, this plan pays first — TRICARE is the secondary payer to other health insurance under its double-coverage rule (Medicaid is the only coverage it pays ahead of). CHAMPVA likewise pays last: "In double coverage situations, CHAMPVA would be the last payer." If the child also has Medicaid, this plan is primary and Medicaid pays last.[8][9][10][11][12]
Ask the plan: Benefits verification with both plans: funding type, which is primary for the child, and whether the secondary plan requires its own authorization.
Not published. Aetna's ABA Medical Necessity Guide and CPB 0554 set medical-necessity criteria and precertification requirements but say nothing about which ABA codes may be delivered remotely, or with which place-of-service code.[5][1]
Ask the plan: Aetna provider services at the number on the member's ID card, and the plan's telehealth/virtual-care policy — confirm before scheduling remote 97155 or 97156.
Coverage decides whether Aetna in Colorado 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.
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.[5]
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.[5]
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.[5]
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. The guide does publish typical intensity bands — comprehensive ABA 10–25 hours/week, focused ABA 1–20 hours/week — as clinical guidance, not claim edits.[5]
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.
Blocked on: The Aetna provider manual and your participation agreement's documentation clause.
Yes — under the carrier's national policy for ASD, layered on Colorado's mandate (C.R.S. § 10-16-104(1.4)) for fully-insured plans. Self-funded employer plans are exempt from the mandate, so always verify plan funding type first.
It applies to all Colorado-issued or renewed health benefit plans (short-term limited-duration and individual grandfathered plans excepted), with no age limits and no dollar caps — the historical $34K/$12K annual ABA caps were removed from the statute. Self-funded ERISA plans are exempt by preemption.
Yes — ASD only (F84.0-F84.9) per the national policy, unlike Health First Colorado, which opens its benefit without an autism diagnosis. If a family lacks a diagnosis and holds a commercial Aetna plan, the diagnostic evaluation comes first.
Commercial ABA rates are not published — they are negotiated in your participating-provider agreement. Benchmark against the Health First Colorado fee schedule, and treat rate-setting as part of contracting.
