For an intake team in Kentucky, an Aetna commercial card means three layers: Aetna’s national ABA medical necessity guide, Kentucky’s autism mandate in KRS 304.17A-142, and the plan’s funding type, which decides whether the mandate applies. Aetna Better Health of Kentucky, the Medicaid plan, has its own guide.
Aetna’s ABA medical necessity guide requires a DSM-5 ASD diagnosis (F84.0, F84.3–F84.9) from an appropriate provider, functional impairment on a standardized scale in the past 12 months, a measurable treatment plan, and hours justified by a severity table; progress is evaluated every six months. Its only state exhibit is Maryland, so Kentucky plans get the national criteria plus the mandate. Aetna’s behavioral health precertification list includes all ten ABA codes, 97151 through 97158, 0362T and 0373T, submitted through Availity.[1][3]
Kentucky’s autism mandate is KRS 304.17A-142. Every health benefit plan "issued or renewed on or after January 1, 2019, shall provide coverage for the diagnosis and treatment of autism spectrum disorders," and treatment expressly includes "applied behavior analysis prescribed or ordered by a licensed health or allied health professional" and habilitative or rehabilitative care "including applied behavior analysis." The 2018 amendment removed the old age bands and dollar caps: coverage "shall not be subject to any maximum annual benefit limit, including any limits on the number of visits an individual may make to an autism services provider," and cost-sharing may be no less favorable than for other medical services. For ongoing outpatient treatment the insurer may request a utilization review "not more than once every twelve (12) months" unless the insurer and the treating physician or psychologist agree to more, may ask for records showing medical necessity and improved clinical status, and may request a treatment plan with diagnosis, type, frequency, anticipated duration, goals and update frequency; goals must be "clearly defined, directly observed, and continually measured." Plans need not pay for services in an IEP, IFSP or other publicly funded program, for services by a relative who would not otherwise charge, or for "services provided by persons who are not licensed as required by law." KRS 304.17A-144 also requires each insurer to give members an autism liaison who explains the ABA benefit, the prior-authorization process and documentation, ABA claim coding, and appeal rights. The mandate reaches fully insured plans; self-funded employer plans answer to ERISA instead.[6][7]
Kentucky licenses behavior analysts under KRS Chapter 319C through the Kentucky Applied Behavior Analysis Licensing Board (BACB lists Kentucky licensure since 2010). No one may practice or "render services designated as applied behavior analysis" in Kentucky without a license, except people delivering ABA in a public school setting, implementing ABA for an immediate family member or as a supervisee, other licensed health professionals within their own scope, and people providing Medicaid waiver services (KRS 319C.020). A licensed behavior analyst must hold and keep an active BCBA; a licensed assistant behavior analyst an active BCaBA, supervised by a certified behavior analyst (KRS 319C.080). The practice of ABA "shall not include diagnosis" (KRS 319C.010(8)), so the autism diagnosis must come from another licensed clinician. A BCBA licensed in another state can get a Kentucky license through KRS 319C.090 (valid license elsewhere, KRS 319C.080 requirements met, no pending discipline), but cannot simply treat a Kentucky child remotely: the board’s telehealth rule says "a person providing applied behavior analytic services via telehealth to a person physically located in Kentucky while services are provided shall be required to be licensed by the board" (201 KAR 43:100). For commercial telehealth, KRS 304.17A-138 likewise lets a plan require the telehealth provider to be licensed in Kentucky or under a recognized interstate compact. On rates, commercial ABA rates are negotiated and unpublished; the public benchmark is the Kentucky Medicaid fee-for-service schedule (2026: 97153 $12.18 per 15 minutes for an RBT; 97155 $21.99 for a licensed behavior analyst).[13][14][15][16][17][8][18][19]
Aetna publishes no ABA rate table. Its provider manual (6/26) says "The rates and compensation under your agreement are subject to the Aetna coding/claim edit policies," and where a provider has both an intermediary and a direct agreement, "your direct Aetna rates will apply unless we specifically notify you otherwise." Get rates from your Aetna agreement. Kentucky’s prompt-pay law requires an insurer to pay a clean claim, or send notice denying or contesting it, "within thirty (30) calendar days from the date that the claim is received" (KRS 304.17A-702), with interest added automatically on late clean claims at 12 percent a year for the first 30 days late, 18 percent for days 31–60, and 21 percent after that (KRS 304.17A-730). Self-funded ERISA plans are outside the state statute.[5][10][11]
Aetna’s Health Care Professional Toolkit (6/26) publishes no claim filing deadline: the limit for initial, corrected and secondary claims is the one in your Aetna participation agreement, and claim disputes "Must be submitted within contractual timeframes." The toolkit defines a clean claim as one "received in a timely manner" with all required data, and says a clean claim "Doesn’t involve coordination of benefits," so secondary claims sit outside the clean-claim clock. It publishes no check-run or weekly cut-off schedule.[5][10][11]
Aetna’s ABA medical necessity guide (©2026) sets what a renewal must show: the plan records baseline levels of each target behavior by "frequency, rate, symptom intensity or duration, or other objective measures," with "quantifiable criteria for progress"; where target behaviors have improved, documentation of that improvement is included, and where they have not, documentation of "modification of the treatment, additional assessments that have been conducted, and/or there has been appropriate consultations from other staff or experts." "A member’s progress is to be evaluated every six months," and the guide relies on "Repeated measurement with standardized measures to assess progress." It does not require graphs and sets no data-recency window.[1]
The questions that decide whether a family can start with Aetna in Kentucky, and what they have to bring. Each maps onto something intake should ask on the first call.
No expiry on the diagnosis, but functional impairment must be shown "on a standardized scale of functioning in the past 12 months."[1]
"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)." Kentucky excludes diagnosis from ABA practice (KRS 319C.010(8)).[1][13]
CPB 0648 names ADI-R, ADOS-2, CARS-2 and the Asperger Syndrome Diagnostic Scale; the ABA guide requires a standardized functional measure (Vineland-3, ABAS, VB-MAPP or ABLLS as examples).[2][1]
Aetna’s national ABA documents require precertification, not a referral. Aetna publishes no ABA order form or validity period, and its provider manual (6/26) says members "may access behavioral health care … through direct access to the behavioral health provider." A PCP referral matters only on plans that require referrals for specialist care; a clean claim then includes "a corresponding referral (whether in paper or electronic format), if required for the applicable claim." The manual names no ABA-specific referring-provider (box 17) requirement. For a fully insured Kentucky plan, KRS 304.17A-142 defines covered ABA as ABA "prescribed or ordered by a licensed health or allied health professional," so keep a signed order or prescription on file; the insurer may also request a treatment plan for continuing services. Self-funded ERISA plans sit outside the statute.[3][1][6][5]
Aetna’s guide sets no age cap; its age ranges are typical, not limiting. For fully insured Kentucky plans issued or renewed on or after January 1, 2019, KRS 304.17A-142 carries no age limit and bars any maximum annual benefit or visit limit on autism treatment. Self-funded ERISA plans are outside the statute, so plan funding type decides whether that binds.[1][6]
Ask the plan: Live benefits verification: establish fully insured vs. self-funded ERISA, then the plan’s age terms.
Aetna’s provider manual says 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." For fully insured Kentucky plans, KRS 304.17A-138 requires telehealth coverage "equivalent to the coverage for the same service provided in person" (unless a lower rate is contracted), bars requiring the provider to be physically present unless the provider decides it is necessary, bars PA for telehealth "that would not be required if a service were provided in person," and lets the plan require a Kentucky (or compact) license. Aetna’s current ABA telehealth code list is not public.[5][8]
Ask the plan: Availity or the precertification line: ask whether the plan is fully insured in Kentucky or self-funded (and opted out), and which ABA codes, POS and modifier Aetna pays by telehealth.
Depends on how the plan is funded. Fully insured Kentucky plans fall under KRS 304.17A-607: a utilization review decision on urgent care is due "no later than twenty-four (24) hours after obtaining all necessary information," and on non-urgent care "within five (5) days of obtaining all necessary information" (limited to face-to-face evaluation results, any required second opinion, and information the Department of Insurance designates). A missed deadline "shall be deemed to be a prior authorization for the health care services." For ongoing autism treatment, KRS 304.17A-142 limits utilization review to once every 12 months unless the insurer and the treating physician or psychologist agree otherwise. Self-funded employer (ERISA) plans follow 29 CFR 2560.503-1: pre-service decisions "not later than 15 days after receipt of the claim," with one 15-day extension. Aetna publishes no Kentucky-specific ABA turnaround.[9][6][20]
Ask the plan: At benefits verification ask whether the plan is fully insured (Kentucky-regulated) or self-funded (ERISA), and what reauthorization lead time Aetna expects.
For a child on two group plans, Kentucky follows the birthday rule: when the parents are married, are not separated, or share joint custody without a decree assigning coverage, the plan of the parent "whose birthday is earlier in the year" is primary; same birthday, the plan that has covered a parent longer; a court decree naming the responsible parent controls (806 KAR 18:030). If the plans cannot agree within 30 calendar days of having everything needed, they pay in equal shares and settle afterwards. That rule binds state-regulated group plans; a self-funded plan sets its own order. If the child also has Kentucky Medicaid, the commercial plan pays first: Medicaid MCOs "cost avoid" claims when other coverage is known (42 CFR 433.139).[12][21]
Ask the plan: Ask Aetna at benefits verification for the coordination-of-benefits order (and whether a self-funded plan uses the birthday rule).
Coverage decides whether Aetna in Kentucky 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’s guide requires services to be provided directly or billed by licensed behavior analysts in states with licensure laws (Kentucky is one), BCBAs, or psychologists where in scope, with supervision of others "in line with practice standards." Its participation criteria (5/26) require "A minimum of one hour of face-to-face supervision" of an unlicensed or noncertified paraprofessional "for each 10 hours of applied behavior analysis," the supervisor "onsite with the child at least one hour a month," and all BCBAs, BCaBAs and paraprofessionals to "meet state requirements." Kentucky’s board rule (201 KAR 43:050) governs supervision of licensed assistants and temporary licensees.[1][4][22]
No per-day or per-week cap. Hours follow the guide’s severity table (typical 10–25 hours a week comprehensive, 1–20 focused; typical, not caps), and QHP protocol modification may be authorized at 1–2 hours per 10 hours of treatment by protocol. Kentucky’s mandate bars visit limits on autism treatment in fully insured plans.[1][6]
Outpatient ABA is setting-neutral in the guide; inpatient, residential or partial hospitalization use that level of care’s criteria. KRS 304.17A-142 does not require plans to cover services in an IEP or IFSP.[1][6]
Services must be "provided directly or billed by licensed behavior analysts (in states with behavior analyst licensure laws)," BCBAs, or psychologists in scope. In Kentucky that means a licensed behavior analyst (KRS 319C).[1][14]
Not addressed in Aetna’s published ABA guide or precertification list. The medical necessity guide and the provider manual also say nothing about ABA at the same time as speech or occupational therapy.[1][5]
Ask the plan: Aetna provider services or your participation agreement.
Not addressed in Aetna’s ABA guide; it sets treatment-plan content, not who signs session notes.[1]
Ask the plan: Your Aetna participation agreement and the Aetna Behavioral Health documentation standards.
No. Aetna’s ABA medical necessity guide asks for objective baseline measures, quantifiable progress criteria, standardized re-measurement and a six-monthly progress evaluation, with treatment changes documented where there is no improvement, but it does not require graphs or set a data-recency window.
Aetna’s provider toolkit publishes no filing limit; the participation agreement sets it for initial, corrected and secondary claims, and a claim involving coordination of benefits is not a "clean claim." No check-run schedule is published.
Yes, under its national guide for ASD, with Kentucky’s KRS 304.17A-142 mandate layered on for fully insured plans. Self-funded employer plans follow their own documents.
No. Since January 1, 2019 KRS 304.17A-142 covers diagnosis and treatment of autism, including ABA, without any maximum annual benefit or visit limit, and with no age limit in the text.
Yes. Kentucky requires a KRS 319C license to practice ABA, and Aetna’s guide requires a licensed behavior analyst in states with licensure laws.
For fully insured plans, within 30 calendar days of receipt (KRS 304.17A-702), with interest of 12–21 percent a year on late clean claims.
