Ambetter from Nebraska Total Care is the Marketplace (ACA individual) product sold under the Nebraska Total Care name; the 2026 plans are underwritten by Celtic Insurance Company. It is not the Nebraska Total Care Medicaid plan: different contract, different rules, and cost sharing. Two facts drive intake. First, Nebraska's autism mandate does not apply to it — the statute excludes non-grandfathered individual plans that must include essential health benefits — so the 25-hour weekly cap is not in play. Second, the plan's own 2026 Evidence of Coverage covers ABA anyway, and states "No limitation exists within the benefits for applied behavior analysis services," with prior authorization for medical necessity under Centene policy CP.BH.104.
An Ambetter card is not a Heritage Health card. The Nebraska Total Care Medicaid line follows the state Medicaid Service Definitions and NE.CP.BH.105; the Ambetter line follows its Evidence of Coverage and Centene's commercial clinical policy CP.BH.104. Network participation is product-specific, authorization goes through Ambetter's own portal and Utilization Management line (1-833-890-0329), and the family owes Marketplace cost sharing. The 2026 Evidence of Coverage lists ABA among covered autism benefits — "Evaluation and assessment services," "Applied behavior analysis therapy," "Behavior training and behavior management" and more — "when prescribed by a physician or behavioral health practitioner," with no ABA benefit limit and prior authorization for medical necessity.[1][2]
Neb. Rev. Stat. § 44-7,106 says plainly: "Nothing in this subsection applies to non-grandfathered plans in the individual and small group markets that are required to include essential health benefits under the federal Patient Protection and Affordable Care Act." A Marketplace plan is exactly that. So the mandate's under-21 scope and its 25-hour weekly cap do not bind Ambetter; its Evidence of Coverage does, and it sets no ABA limit. Nebraska's essential-health-benefit benchmark plan excludes autism services including ABA, which makes Ambetter's coverage a plan choice rather than a legal floor — re-check the Evidence of Coverage each plan year.[6][7][1]
The request is built around the diagnostic evaluation and a recent behavior assessment. A comprehensive diagnostic evaluation within three years (or a fresh diagnostic interview within 12 months when the evaluation is three to five years old), using at least one clinician tool and one parent tool; a behavior assessment by a BCBA completed no more than two months before treatment starts; and a treatment plan signed by the BCBA and the parent that justifies the setting and the hours. Hours stay within six a day and 30 a week unless documentation justifies more, and under 20 a week for a child in school full time. Protocol modification (97155) should run at least two hours a week or 10% of direct hours, and no more than 20%. The plan and behavior assessment are updated at least every six months, and attendance below 80% of authorized hours needs an explanation.[3]
The questions that decide whether a family can start with Ambetter from Nebraska Total Care, and what they have to bring. Each maps onto something intake should ask on the first call.
None stated. The Evidence of Coverage's autism benefit has no age limit and says "No limitation exists within the benefits for applied behavior analysis services," and CP.BH.104 sets none. The Nebraska mandate's under-21 scope does not govern here, because the mandate does not reach non-grandfathered individual plans.[1][3][6]
Three years, with a bridge to five. To start treatment, CP.BH.104 needs a comprehensive diagnostic evaluation (CDE) "conducted in the past three years," or — if the CDE is three to five years old — "A diagnostic interview/evaluation has been conducted within 12 months of the authorization request." Continuation needs a CDE "within the past five years," and a re-evaluation can be required sooner for a provisional diagnosis, a missing formal evaluation, or a mismatch between the tools and the diagnosis. The behavior assessment must be "completed no more than two months prior to the start of the initial treatment authorization."[3]
"The documented diagnosis of ASD is established by a licensed physician, psychologist, or other licensed professional with specialized training in diagnosis and treatment of ASD, or a provider otherwise authorized under state law/regulation." The same group may make the ABA recommendation, which can sit inside the diagnostic evaluation.[3]
Two instruments minimum. The diagnosis must rest on the CDE, "including at least one primary clinician tool and one parent/caregiver tool." Clinician tools: STAT, ADI-R, CARS/CARS-2, ASRS, ADOS/ADOS-2, EarliPoint, RITA-T or CSBS DP-ITC. Parent tools: M-CHAT/M-CHAT-R/F, SCQ, ASSQ, CAST, SRS-2 Parent Report, SWYC POSI or CSBS DP-ITC; other evidence-based tools are reviewed case by case. The ABA behavior assessment then needs a functional behavior assessment and/or a skills assessment such as VB-MAPP, ABLLS-R, AFLS, PEAK, EFL, SSIS or Socially Savvy — and if the Vineland is used as a skills assessment, a direct skills assessment is required as well.[3]
A prescription and a recommendation. The Evidence of Coverage covers autism services "when prescribed by a physician or behavioral health practitioner," and CP.BH.104 requires a "Recommendation for ABA" from the diagnosing class of provider, which "may be included within the CDE" and is required whenever an initial or updated CDE is required.[1][3]
Ambetter's 2026 manual still prints the old clocks: prospective urgent "Within 3 calendar days of receipt of the request," prospective non-urgent "Within 15 calendar days of receipt of the request," concurrent urgent "Within 1 calendar day," retrospective 30 calendar days. Nebraska's LB 77, operative January 1, 2026, is tighter for health carriers' plans: a decision "within seventy-two hours after obtaining all necessary information" for urgent care and "within seven days after obtaining all necessary information" for nonurgent care, "Health care services are deemed authorized if a utilization review agent fails to comply with the deadlines," and a prior authorization "shall be valid for at least one year." Hold Ambetter to LB 77.[2][8]
Ask the plan: Ambetter Utilization Management 1-833-890-0329 — ask which turnaround it now applies to nonurgent ABA requests.
The Evidence of Coverage uses the birthday rule: for a child on both parents' plans, "the plan of the parent whose birthday falls earlier in the year (excluding year of birth) shall be primary," and on the same birthday "the plan which covered the parent longer will be primary." Coverage "will not be changed or limited for reason of a member being eligible for coverage under the Medicaid program," and Ambetter will repay the state when Medicaid has paid for covered services — Ambetter pays before Medicaid. When Ambetter is secondary, the claim is due within 365 days of the primary payer's Explanation of Payment. TRICARE pays after Ambetter ("TRICARE shall be last pay").[1][2][9]
Covered, with no ABA code list published. The Evidence of Coverage covers "medically necessary telehealth services," and telehealth outside its Virtual 24/7 Care vendor carries "the same cost sharing as the same health care services when delivered to a member in person." CP.BH.104 names telehealth as an ABA modality and points providers to state allowances and the CASP telehealth practice parameters. The provider manual: telehealth claims use POS 02 or 10, and "providers will be reimbursed at the facility rate unless otherwise required per state guidelines."[1][3][2]
Ask the plan: Ambetter Utilization Management 1-833-890-0329 — confirm which ABA codes it will authorize by telehealth for this member.
Coverage decides whether Ambetter from Nebraska Total Care 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.
A range, in CP.BH.104: the treatment plan must show "Adaptive Behavior Treatment with Protocol Modification occurs for at least two hours per week or 10% of the direct service hours provided (whichever is greater), and no more than 20% of direct service hours provided (unless clinical documentation justifies)," and that ABA "will be delivered or supervised by an ABA-credentialed professional." The behavior assessment must be completed by a BCBA or BCBA-D "or other duly certified, licensed, or registered equivalent provider, as defined by state law/regulation."[3]
No benefit cap, but a medical-necessity ceiling. The 2026 Evidence of Coverage: "No limitation exists within the benefits for applied behavior analysis services." CP.BH.104 then sizes the request: hours must "not exceed six hours per day up to a total of 30 hours per week" unless clinical documentation justifies more, should be "less than 20 hours per week if attending school full-time," and may be authorized lower than requested if a lower intensity is sufficient. The Nebraska mandate's 25-hour weekly cap does not apply — the mandate excludes non-grandfathered individual plans that must include essential health benefits, which is what a Marketplace plan is.[1][3][6]
Signatures attach to the plan and the diagnosis more than to the session note. CP.BH.104: "All treatment plan documents (treatment plan, goals, and behavior intervention plan, if submitted separately) include the HIPAA-compliant signature, credentials, and role of the BCBA/BCBA-D responsible for the member/enrollee's care, the member/enrollee's parent or legal guardian, and any additional person who reviewed and signed the plan," and the diagnostic report must carry the "Evaluator's name, signature, and credentials." For records generally, Ambetter's manual asks that documentation be "clear, concise, consistent, complete, legible, and meets CMS signature guidelines (each encounter must stand alone)." No signing deadline is published.[3][2]
Home, clinic, school and community are all contemplated — CP.BH.104: "Services may be provided in various settings (e.g., home, clinic, school, community) and modalities (e.g., in-person, telehealth)" — but the setting is justified, not assumed: the treatment plan needs a "Treatment setting with rationale for how the setting will maximize treatment outcomes," and school-based work needs its own plan with a titration timeline. Not medically necessary: "Services that are otherwise covered under the Individuals with Disabilities Education Act (IDEA)."[3]
Not published. CP.BH.104 reproduces the CPT descriptor for 97155 ("which may include simultaneous direction of technician") but states no billing rule for 97153 and 97155 on the same clock time.[3]
Ask the plan: Ambetter Utilization Management 1-833-890-0329 — ask whether 97155 pays alongside 97153 for the same time on the Marketplace plan.
Not published. Neither the Evidence of Coverage, the provider manual nor CP.BH.104 says whose NPI carries technician time. One billing point the Evidence of Coverage does make: "If multiple services are provided on the same day by different providers, a separate copayment and/or coinsurance will apply to each provider."[1]
Ask the plan: Ambetter provider services / your Provider Relations Representative, and your participation agreement for the rendering-provider field.
Yes. The 2026 Evidence of Coverage covers applied behavior analysis for autism spectrum disorder when prescribed by a physician or behavioral health practitioner, states that no limitation exists within the ABA benefit, and requires prior authorization. Marketplace cost sharing applies.
No. The Nebraska autism mandate excludes non-grandfathered individual and small-group plans that must include essential health benefits, which covers Marketplace plans. Ambetter's own criteria (CP.BH.104) look for 6 hours a day and 30 hours a week or less unless more is clinically justified.
No. Nebraska Total Care operates the Heritage Health Medicaid plan, while Ambetter is a Marketplace product underwritten by Celtic Insurance Company, with its own benefits, network, prior-authorization route and cost sharing. This directory has a separate guide for the Medicaid plan.
All of them: Ambetter's Pre-Auth Needed tool returns "Pre-authorization is required for all providers" for 97151 through 97158, 0362T and 0373T.
