For an intake team in South Carolina, an Aetna card means three layers: Aetna’s national ABA criteria, South Carolina’s autism mandate in S.C. Code § 38-71-280, and the plan’s funding and size, which decide whether the mandate applies at all. South Carolina’s mandate is narrower than most: group plans only, and it carries an age ceiling and a dollar cap.
Aetna covers ABA for autism spectrum disorder under its ABA medical necessity guide (©2026), with CPB 0648 for the ASD workup; CPB 0554 (last review 10/14/2026) considers ABA "experimental, investigational, or unproven" for non-ASD indications. Medical necessity requires a DSM-5 ASD diagnosis by an appropriate provider, a standardized functional measure from the past 12 months showing impairment at least one standard deviation below the mean (or a significant risk of harm), and a treatment plan with measurable targets, generalization and discharge planning; progress is evaluated every six months. Aetna’s behavioral health precertification list (eff. 8/1/2024) names all ten ABA codes, 97151 through 97158, 0362T and 0373T; most requests go through Availity. The guide’s only state exhibit is Maryland’s, so no South Carolina-specific criteria apply. Aetna is not one of South Carolina’s five Medicaid plans.[1][2][3][4][18]
South Carolina’s autism mandate, S.C. Code § 38-71-280 (2007 Act No. 65, known as Ryan’s Law), requires a "health insurance plan" to "provide coverage for the treatment of autism spectrum disorder." The definition is narrow in three ways. It reaches group policies and group benefit plans plus the State Health Plan, and it expressly excludes the individual market, individually underwritten plans and plans sold to small employers; self-funded employer plans answer to ERISA instead. It defines autism spectrum disorder by three older DSM labels (autistic disorder, Asperger’s syndrome, PDD-NOS). And the child must be "diagnosed with autistic spectrum disorder at age eight or younger," with benefits provided to "any eligible person under sixteen years of age." Coverage "is limited to treatment that is prescribed by the insured’s treating medical doctor in accordance with a treatment plan," which must state the diagnosis, treatment by type, frequency and duration, goals, the update schedule and the doctor’s signature; the plan "may only request an updated treatment plan once every six months." Dollar limits, deductibles and coinsurance may not be less favorable than for physical illness, but "Coverage for behavioral therapy is subject to a fifty thousand dollar maximum benefit per year," adjusted each January 1 by CPI. The Department of Insurance set that cap at $73,400 for calendar year 2026 (Bulletin 2025-09). The statute lets plans keep coordination of benefits, participating-provider rules, utilization review and "restrictions on services provided by family or household members."[8][9]
South Carolina does not license behavior analysts. Title 40, Chapter 75 of the Code (the LLR board for counselors, marriage and family therapists, addiction counselors and psycho-educational specialists) has no behavior-analyst article, the 2021 licensure bill (H. 3731) never left committee, and the BACB’s licensure table does not list the state. Practically, BACB certification is the credential every payer checks. Two payer-level location rules matter more than any license. SC Medicaid requires ASD providers, including those working by telehealth, to be located within the South Carolina Medical Service Area (SCMSA; SCDHHS describes it as within 25 miles of the state border). BlueCross BlueShield of South Carolina’s ABA policy says the BCBA completing the assessment "must be located in the same state as the member or in a contiguous county." On claims, the state prompt-pay law (S.C. Code § 38-59-230) makes insurers pay a clean claim within 20 business days if filed electronically and 40 business days on paper, with interest after that; a "clean claim" must be received "within one hundred twenty business days" of the service. Overpayment recovery may not start more than 18 months after payment, except for fraud, self-insured plans or government programs. Commercial ABA rates are negotiated and unpublished; the public benchmark is the SC Medicaid ASD fee schedule (97153 $14.88 per 15-minute unit).[13][19][14][20][21][22][10][17]
Aetna publishes no ABA rate table. Its provider manual (6/26) treats payment as a contract term: "The rates and compensation under your agreement are subject to the Aetna coding/claim edit policies," and where a provider has both an intermediary contract and a direct agreement, "your direct Aetna rates will apply unless we specifically notify you otherwise." Get rates from your Aetna agreement. For a public benchmark, SC Medicaid’s ASD fee schedule pays 97153 at $14.88 per 15 minutes; commercial contracts are negotiated separately. South Carolina law lets a participating physician request a contracted fee schedule for up to 100 codes (S.C. Code § 38-59-220), but that right is written for physicians, not BCBAs.[6][17][10]
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 fall outside the clean-claim clock. For insured South Carolina plans, S.C. Code § 38-59-230 requires payment of a clean claim within 20 business days if filed electronically and 40 business days on paper, and § 38-59-210 only treats a claim as clean if it is received within 120 business days of the service. Aetna publishes no check-run or weekly cut-off schedule.[6][10]
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 South Carolina, and what they have to bring. Each maps onto something intake should ask on the first call.
No expiry on the diagnosis, but medical necessity requires functional impairment on a standardized scale administered in the past 12 months. For a mandated plan, the child must have been diagnosed at age eight or younger.[1][8]
A DSM-5 ASD diagnosis by "an appropriate provider (i.e. licensed psychologist/psychiatrist, physician or other health care" professional qualified to diagnose). CPB 0648 describes the professionals involved in an ASD evaluation.[1][3]
CPB 0648 names ADI-R, ADOS-2, CARS-2 and the Asperger Syndrome Diagnostic Scale as tools used with clinical assessment. The ABA guide requires a standardized functional measure from the past 12 months (Vineland-3, ABAS, VB-MAPP or ABLLS as examples).[3][1]
Aetna’s national ABA policies require no physician referral; they require precertification of all ten ABA codes. For a group plan subject to S.C. Code § 38-71-280, covered treatment must be "prescribed by the insured’s treating medical doctor in accordance with a treatment plan" signed by that doctor; the plan may ask for an updated plan only once every six months. Individual, small-employer and self-funded plans are outside the statute.[4][1][8]
Aetna’s national ABA guide sets no age cap. For a South Carolina group plan subject to S.C. Code § 38-71-280, coverage runs to "any eligible person under sixteen years of age" who was diagnosed at age eight or younger, with behavioral therapy capped at $73,400 for 2026 (DOI Bulletin 2025-09). Individual, small-employer and self-funded plans are outside the statute.[1][8][9]
Ask the plan: Live benefits verification: establish group size and funding (mandated insured group vs. individual, small-group or self-funded), then the plan’s own age terms.
Aetna’s provider manual (6/26) 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." Its Telemedicine and Direct Patient Contact Payment Policy lists 97151–97158 among eligible two-way synchronous codes billed with GT, 95 or FR, split by line of business, but the posted policy shows a last review of June 2021, so treat the list as perishable.[6][7]
Ask the plan: Availity or the precertification line on the card: ask whether a self-funded plan opted out of telehealth, and which ABA codes, POS and modifier Aetna pays by telehealth.
No South Carolina statute read sets a prior-authorization decision deadline for commercial plans. Title 38, Chapter 70 (utilization review) sets minimum standards for review programs, including notice of an adverse decision "within five business days" and a reconsideration or appeal procedure, but no clock for deciding a request. Federal claims rules therefore set the outer limit: ERISA plans must decide a pre-service claim "not later than 15 days after receipt of the claim" (one 15-day extension; urgent care within 72 hours), and insured group coverage must follow the same rule under 45 CFR 147.136. Aetna publishes no South Carolina-specific ABA turnaround.[11][15][16]
Ask the plan: At benefits verification ask whether the plan is insured or self-funded and what decision and reauthorization lead times Aetna applies.
For a child on two group plans, South Carolina Regulation 69-43 sets the birthday rule: 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" (month and day only); for separated or divorced parents the custodial parent’s plan pays first unless a court decree assigns health costs to the other parent. The regulation binds insured group plans; a self-funded plan sets its own order. If the child also has SC Medicaid, the commercial plan pays first: Medicaid is payer of last resort (42 CFR 433.139), and SCDHHS asks for its own ASD authorization only "if Medicare or the primary carrier denied the service or the service is considered not covered." TRICARE pays after this plan (10 U.S.C. 1079(i)(1)); CHAMPVA is the last payer (38 CFR 17.270).[12][23][20][24][25]
Ask the plan: Ask Aetna at benefits verification for the member’s coordination-of-benefits order (and whether a self-funded plan uses the birthday rule), and record every other coverage the child has.
Coverage decides whether Aetna in South Carolina 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 Network Participation Criteria (5/26): ABA services "must be provided directly or supervised by individuals licensed by the state or certified by the Behavior Analyst Certification Board," supervised staff may be a BCaBA "or a paraprofessional," and Aetna requires "A minimum of one hour of face-to-face supervision" of an unlicensed or noncertified paraprofessional "for each 10 hours of applied behavior analysis," plus the supervisor "onsite with the child at least one hour a month." South Carolina has no state license, so BACB certification is the qualifying credential.[5][1][13]
No per-day or per-week cap is published; hours follow the guide’s severity assessment, with typical intensities of 10–25 hours a week for comprehensive and 1–20 for focused programs (typical, not caps). A mandated South Carolina group plan may still apply the $73,400 annual behavioral-therapy cap for 2026.[1][8][9]
Outpatient ABA is setting-neutral in Aetna’s guide, which expects coordination with the school district. Aetna publishes no South Carolina-specific setting rule.[1]
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 mandates, plan documents or contracts say otherwise. South Carolina has no behavior-analyst license, so the BCBA is the billing credential.[1][14]
Not addressed in Aetna’s published ABA policies (the medical necessity guide, CPB 0554, CPB 0648). ABA alongside speech, OT or PT: Aetna's ABA medical necessity guide has no same-clock-time rule for ABA with another therapy; it requires "ongoing collaboration and coordination with existing providers and/or the school district, as applicable."[1][2][1]
Ask the plan: Aetna provider services, your participating-provider agreement, or a written coding determination from Aetna Behavioral Health.
Not addressed. Aetna sets treatment-plan content requirements but not who signs a session note or by when.[1]
Ask the plan: Your Aetna participating-provider 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 does not publish one; it is set in your participation agreement. For insured South Carolina plans, a claim filed within 120 business days of the service that is otherwise clean must be paid within 20 business days electronically (40 on paper) under S.C. Code § 38-59-230.
Yes, under its national ABA criteria for ASD. For insured large-group plans and the State Health Plan, South Carolina’s Ryan’s Law also applies; individual, small-group and self-funded plans follow their own documents.
Group plans must cover autism treatment prescribed by the child’s treating medical doctor under a treatment plan, for children under 16 who were diagnosed by age 8, with behavioral therapy capped at $73,400 for 2026.
Yes. 97151 and the other nine ABA codes are on Aetna’s behavioral health precertification list.
No. South Carolina does not license behavior analysts; Aetna accepts a board-certified behavior analyst as the billing credential where there is no state license.
For insured plans subject to state law, within 20 business days of an electronic clean claim or 40 business days on paper (S.C. Code § 38-59-230), with interest after that. Self-funded plans are outside the statute.
