Cigna / Evernorth ABA coverage in North Carolina: the intake guide.

EN0499 puts no expiry on the ASD diagnosis, but it requires the name, credentials and licensure type of the diagnosing clinician and the date on which the diagnosis was most recently made — and a diagnosis termed provisional, proposed, potential, at risk of or rule out is not a confirmed diagnosis, nor is IDEA educational identification. The recency clocks sit on the data instead: the standardized assessment instrument must have been administered within 60 days prior to the start of treatment, quantitative baseline data collected within 60 days prior to start, current data within 60 days of the authorization request, a standardized instrument completed no more than one year prior for continued treatment, and a fresh standardized assessment after any break in treatment greater than 60 calendar days.^[1]

The ASD diagnosis (ICD-10 F84.0–F84.9 except F84.2, Rett syndrome) must be made under DSM-5-TR criteria by a healthcare professional who is licensed to practice independently and whose licensure board considers diagnostics to be within their scope of practice. The ABA assessment itself is performed by a Board Certified Behavior Analyst, a Licensed Behavior Analyst, or a mental health clinician licensed to practice independently who has documented training in ABA.^[1]

EN0499 mandates no single named instrument. It requires a reliable, valid and standardized assessment instrument measuring the DSM-5-TR ASD domains — social communication and social interaction, and restricted, repetitive patterns of behavior, interests or activities — completed in its entirety and as designed, by someone trained to administer and interpret it, with reliability and validity established for the population tested, in the most current edition rather than an obsolete one (the policy’s own example: Vineland-3, not Vineland-II). The report must carry the date of administration, the respondent or participant name, the form type where applicable, and standardized scores and score tables or scoring grids.^[1]

No referral, order or prescription is required under EN0499. Cigna’s notable front-door change is on authorization: per the Evernorth autism resource guide, prior authorization is no longer required for assessment codes 97151, 97152 or 0362T with a diagnosis of autism, as long as the provider is independently licensed or a BCBA and the member’s policy covers ABA — submit the claims and they are evaluated for payment. Treatment authorization requires the completed assessment and treatment plan attached to the Applied Behavior Analysis Prior Authorization Form. For a fully insured North Carolina plan the state mandate adds an ordering requirement the carrier policies do not: adaptive behavior treatment must be ordered by a licensed physician or licensed psychologist. The mandate does not reach non-grandfathered individual and small-group plans, and self-funded ERISA plans sit outside state insurance law entirely — establish plan funding type before relying on it.^[2][1][3]

All ABA CPT codes are covered telehealth services per the Evernorth autism resource guide, and EN0499 allows delivery in person, via telehealth, or as a hybrid — the modality chosen on individual characteristics, the treatment plan, caregiver participation, environment, evidence of efficacy and safety, and technological requirements. The requirement that the ABA provider remain in line of sight and close proximity to the individual expressly does not apply to telehealth services. Where treatment is delivered in settings with additional behavioral expectations, telehealth included, the plan must document that the service still meets the definition of direct treatment and direct engagement.^[2][1]

EN0499 sets no age cap on ABA — its glossary, following CASP 2024, states that access to focused intervention "should not be restricted by age, cognitive level, diagnosis, or co-occurring conditions." Age terms come from the member’s benefit plan document, which supersedes the coverage policy, and from any controlling state mandate. North Carolina’s mandate permits coverage to be limited to individuals 18 or younger and capped at $40,000 a year (CPI-indexed from 2017) on fully insured plans — quantitative treatment limits of doubtful enforceability against large-group plans under MHPAEA. The mandate does not apply to non-grandfathered individual and small-group plans, and self-funded ERISA plans are exempt by preemption.^[1][3]

Ask the plan: Live benefits verification, or the Evernorth Autism Care Coordinator team on 877.279.7603 — establish fully insured vs. self-funded ERISA first.

Evernorth (Cigna behavioral health) makes coverage determinations "in accordance with the time frames required under applicable law" and publishes no day counts; for ABA it asks providers "to request authorizations up to 30 days in advance of or two weeks after the start date of service. A delay in request may result in a retrospective review and could delay the determination for up to 30 days." Assessment codes 97151, 97152 and 0362T no longer need PA with an autism diagnosis. So the governing clock depends on funding. For a fully insured plan issued in North Carolina, G.S. 58-50-61(f) governs: "Prospective and concurrent determinations shall be communicated to the covered person's provider within three business days after the insurer obtains all necessary information" — the clock starts on complete information, not receipt, and the statute sets no separate faster clock for an urgent first decision (its expedited track is for appeals). In concurrent review "the insurer shall remain liable for health care services until the covered person has been notified of the noncertification." A self-funded employer plan sits outside state law and follows ERISA: a non-urgent pre-service decision "not later than 15 days after receipt of the claim by the plan", extendable once by up to 15 days; an urgent one within 72 hours; the clock starts when the request is filed, whether or not it is complete; and an urgent request to extend an approved course is decided within 24 hours if made "at least 24 hours prior to the expiration" of the current authorization.^[6][2][7][8]

Ask the plan: At benefits verification, ask whether the plan is fully insured (a policy issued in the state) or a self-funded employer (ERISA) plan — that decides which clock applies — then ask the carrier’s behavioral health precert line its expected ABA turnaround and how early it wants the reauth.

North Carolina’s COB rule for insured group plans (11 NCAC 12 .0514) sets the order: the plan covering the person as employee or subscriber pays before the plan covering them as a dependent; for a child of parents not separated, "the benefits of the Health Plan of the parent whose birthday falls earlier in a year are determined before those of the Health Plan of the parent whose birthday falls later" (same birthday: the longer-running plan first); for separated or divorced parents the custodial parent’s plan pays first, then the custodial parent’s spouse’s, then the non-custodial parent’s, unless a court decree the plan knows of assigns responsibility; Medicaid is expressly outside that rule. Self-funded plans follow their own plan document. Evernorth spells the same order out: the employee/subscriber plan is "always considered the primary payer" over a dependent plan; married parents follow "the 'birthday rule'"; divorced, separated or not-living-together parents follow the custodial rule (custodial parent, their spouse, non-custodial parent, their spouse) unless a court decree assigns it, and joint custody without a named parent falls back to the birthday rule. Paper COB claims need "a copy of the primary payer's explanation of payment (EOP)." Government coverage sorts itself by federal rule: a commercial plan pays before TRICARE, which is secondary to every other health plan but "In any double coverage situation involving Medicaid, CHAMPUS is always the primary payer"; CHAMPVA "is the last payer to OHI"; and Medicaid pays after all of them (42 CFR 433.139), so a child with commercial plus Medicaid needs this plan’s authorization and EOB before Medicaid will pay.^{[9][6][10][11][12]}

Ask the plan: Collect both parents’ plans, dates of birth, and any custody decree at intake; confirm primary/secondary with each carrier’s COB unit (and whether the plan is self-funded) before the first claim.

Case supervision is performed by a BCBA, a Licensed Behavior Analyst, or a mental health professional licensed to practice independently with documented training in ABA. Direct case supervision — occurring concurrently with direct treatment, with the BCBA face-to-face with the individual and with either the RBT or the BCaBA — plus indirect case supervision runs at the generally accepted standard of care of one to two hours per ten hours of direct treatment. When direct treatment is 10 hours per week or less, a minimum of one to two hours per week of direct case supervision is provided. The name and credentials of the person providing supervision must be documented, and supervisory services must coincide with the AMA CPT code descriptions.^[1]

Only one provider can bill for a unit of time, with one exception: CPT codes 97153, 97154 and 97155 during direct supervision, when the BCBA or qualified health care professional directs the technician and both are face-to-face with the patient at the same time. Separately, ABA treatment is not covered or reimbursable when delivered to the same individual at the same time as any other treatment modality — the policy’s own examples are ABA and speech therapy, or ABA and occupational therapy.^[2][1]

Cigna publishes no per-day unit ceiling. All ABA CPT codes bill in 15-minute increments, and all ABA services must be billed with 97151–97158, 0362T and 0373T only. The published limits are structural rather than daily: planned treatment intensity must reflect the severity of the impairments, the goals of treatment and the response to treatment across all settings, and case supervision sits at one to two hours per ten hours of direct treatment. 0362T and 0373T are each reported on a single technician’s face-to-face time, not the combined time of multiple technicians.^[2][1]

A separate written record is expected for each individual receiving ABA, corresponding with each service billed under its CPT code, carrying at least: the start date and time and end date and time for each service, the location of service delivery, the focus of service, a detailed description of the intervention conducted during the time of service, the individuals present, the specific service delivered (direct service, supervision, stakeholder training), and the name, credential where applicable, and signature of the ABA provider who rendered the service.^[1]

Treatment goals must be defined and measured across all settings and environments where treatment will occur — home, clinic, school, community — and quantitative data must be obtained and reported separately by location for each behavior and skill. Services considered primarily educational or vocational in nature, or related to academic or work performance, are not covered or reimbursable. Where services are delivered in environments that carry additional or alternative behavioral expectations (academic setting, vocational placement, telehealth), the plan must document that the service still meets the direct-treatment definition and is not replacing activities that belong to that setting.^[1]

Evernorth does not credential non-licensed or non-certified staff — their services must be billed under the supervising provider. On a CMS-1500 the rendering provider prints their name in box 31 and only a BCBA or other licensed provider is listed in box 33; electronic claims go to Evernorth payer ID 62308. Per the autism resource guide’s code table, 97152, 97153 and 97154 may be provided by a BCaBA or technician but billed only by a BCBA-D, BCBA or licensed mental health provider, while 97151, 97155, 97156, 97157, 97158, 0362T and 0373T are both provided and billed by a BCBA-D, BCBA or licensed mental health provider.^[2]
