For an intake team in South Carolina, a UnitedHealthcare card means three layers: Optum Behavioral Health’s national ABA criteria, South Carolina’s autism mandate in S.C. Code § 38-71-280, and the plan’s funding and size. UnitedHealthcare is not one of South Carolina’s five Medicaid plans, so a UHC card here is commercial (or Medicare).
UnitedHealthcare administers ABA through Optum Behavioral Health under the ABA Supplemental Clinical Criteria (BH803ABASCC; annual review August 2025, interim review April 2026): prior authorization for ABA unless a contract or law says otherwise, with continued-service review looking at use below 80% of authorized hours over a two-week period. Optum’s ABA State Mandates supplement (annual review July 2026) has entries for Arizona, California, Connecticut, Florida, Massachusetts, New Jersey, New York, Ohio and Pennsylvania; South Carolina is not among them, so no South Carolina-specific criteria modify the commercial policy. SCDHHS’s list of Medicaid MCOs does not include UnitedHealthcare.[1][2][6]
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."[7][8]
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).[12][17][13][18][19][20][9][16]
UnitedHealthcare publishes no ABA rate table; Optum pays from the contract. Optum’s National Network Manual (effective Sept. 1, 2026) defines the "Fee Maximum" as the most a participating provider may be paid for a service, adding that "Reimbursement to clinicians is based upon licensure rather than degree." Optum’s commercial ABA Reimbursement Policy (2022RP501A) makes the credential level part of each claim line: HM for an RBT, HN for a BCaBA, HO for a master’s-level BCBA, HP for a doctoral-level provider. Ask Optum network management for your rate sheet. For a public benchmark, SC Medicaid pays 97153 at $14.88 per 15 minutes.[4][5][16]
Optum’s National Network Manual: claims must be received "no more than 90 calendar days from the date of service, or as allowed by state or federal law or the member’s specific benefit plan," and "Any corrections or additions to a claim should be made within 90 days of initial claim receipt." Complete, authorized claims "will be paid within 45 calendar days after Optum receives the claim, or as required by state and federal laws," which may exclude claims needing coordination-of-benefits decisions; the manual sets no separate secondary-claim deadline. For insured South Carolina plans the shorter state clock applies: S.C. Code § 38-59-230 requires payment of a clean claim within 20 business days electronic or 40 on paper. No check-run schedule is published.[4][9]
Optum’s ABA Supplemental Clinical Criteria (review 04/2026) set what each continued-service review needs: progress "assessed and documented for each targeted symptom and behavior … including the same modes of measurement that were utilized for baseline measurement"; progress that includes "rate and percentage of mastered programs, rates of mastered targets, change scores for any outcome measures, updated standardized adaptive measures, and change scores for skills-based assessments"; an assessment of the reasons and modified interventions when there is inadequate progress "within a 6-month period"; and an explanation when use of authorized hours falls below 80% over a two-week period. Treatment plans "are usually reviewed/updated twice annually." The criteria do not require graphs.[1]
The questions that decide whether a family can start with UnitedHealthcare / Optum 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 in the SCC; it must be confirmed with validated tools. For a mandated plan, the child must have been diagnosed at age eight or younger.[1][7]
A diagnosis "issued by a state licensed physician, psychologist, or other state licensed clinician qualified to make such diagnosis."[1]
At least one clinically validated tool from a non-exhaustive list running from screens (M-CHAT, CARS, STAT) to formal diagnostic tools (ADI-R, ADOS/ADOS-2).[1]
No separate referral in the SCC; ABA needs prior authorization. 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.[1][7]
Optum’s Telehealth Billing guide (updated September 2025), commercial plans: "For ABA services, telehealth is only allowed for these 3 CPT codes: 97155, 97156 or 97157." Bill POS 10 (home) or 02. The 97151 assessment and technician 97153 are not on the list, and the SCC say telehealth is meant to supplement, not supplant, in-person care.[3][1]
The SCC carry no age criterion; the member’s benefit plan governs. 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][7][8]
Ask the plan: Provider Express benefits check or the behavioral health number on the card: establish group size and funding first.
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. UnitedHealthcare/Optum publishes no South Carolina-specific ABA turnaround.[10][14][15]
Ask the plan: At benefits verification ask whether the plan is insured or self-funded and what decision and reauthorization lead times Optum 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).[11][22][18][23][24]
Ask the plan: Ask UnitedHealthcare/Optum at benefits verification for the member’s coordination-of-benefits order, and record every other coverage the child has.
Coverage decides whether UnitedHealthcare / Optum 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.
Direct case supervision is required at 1–2 hours for every 10 hours of direct treatment. Technicians work under a BCBA or licensed clinician, and Optum does not recommend parents serving as their own child’s RBT.[1]
No numeric cap; requested hours must be justified by documented need at the least restrictive level, and use below 80% of authorized hours over two weeks must be explained at review. A mandated South Carolina group plan may still apply the $73,400 annual behavioral-therapy cap for 2026.[1][7][8]
Not covered: services that are not ABA, "such as 1:1 aid delivered simultaneously during classroom instruction," or services covered under IDEA; school coordination is allowed.[1]
Each claim line carries a credential modifier under Optum’s commercial ABA reimbursement policy: HM (RBT), HN (BCaBA), HO (master’s-level BCBA or licensed clinician), HP (doctoral). The policy notes that state requirements "may supplement, modify or supersede" it.[5]
Not addressed in the SCC, which define direct case supervision as happening during treatment without stating the billing consequence. ABA alongside speech, OT or PT: Optum publishes no same-clock-time rule for ABA with another therapy. Its supplemental clinical criteria say "ABA services do not duplicate the services provided to or available to the individual by other medical or behavioral services," and require documented coordination with other allied health providers ("occupational therapy, speech therapy, physical therapy and any other applicable providers") "to reduce the likelihood of unnecessary duplication of services"; Optum's ABA CPT FAQ adds that ABA providers should know the child's other therapies, how often they occur and their goals, with ongoing communication documented.[1][1][21]
Ask the plan: Optum National Network Manual and your participating-provider agreement, or a written coding determination from Optum.
Not addressed. The SCC set what must be documented for coverage, not who signs a session note or when.[1]
Ask the plan: Optum National Network Manual (documentation standards) and your participating-provider agreement.
No. Optum’s criteria ask for progress on every target using the baseline measurement method, mastery rates and change scores, updated standardized adaptive measures, and an explanation of low hour use, but they do not require graphs.
90 calendar days from the date of service, or longer where state law or the benefit plan allows; corrections within 90 days of the original claim’s receipt. Optum pays complete claims within 45 days or faster where law requires: 20 business days electronic, 40 paper, for insured South Carolina plans.
Yes, under Optum’s national ABA criteria for ASD, with Ryan’s Law added for insured large-group plans. Self-funded employer plans follow their own documents.
No. SC’s Medicaid MCOs are Absolute Total Care, Healthy Blue, Humana Healthy Horizons, Molina and First Choice by Select Health.
Optum’s commercial guide allows only 97155, 97156 and 97157 by telehealth, billed POS 10 or 02.
Optum’s commercial reimbursement policy names a Registered Behavior Technician as the rendering provider for the HM modifier, so plan on RBT-certified technicians.
