Prior authorization: CDE, recent behavior assessment, and individualized treatment plan required

Prior authorization for initial ABA requires submission of a comprehensive diagnostic evaluation (CDE) meeting recency rules and a recent behavioral assessment (completed ≤2 months prior to the start of the initial treatment authorization) plus an individualized treatment plan that justifies requested hours and includes required signatures and components.

• CDE recency: CDE conducted in past 3 years for initiation; if CDE >3 and <5 years, submit a diagnostic interview completed within 12 months that meets the listed elements [[see cited chunks]].
• Behavioral assessment: completed ≤2 months prior to authorization and includes record review, interviews, rating scales, direct observation/measurement (continuous or discontinuous), and results from at least one FBA or skills assessment.
• Individualized treatment plan: must justify number of treatment hours by level of impairment, domains requiring treatment, treatment history, and response to intervention; include crisis plan, school-based plan as applicable, and BCBA and caregiver signatures.

Prior authorization implied for listed ABA codes; assessments by qualified assessor required

Prior authorization applies to ABA services billed with the policy-listed CPT/HCPCS codes and behavior assessments must be completed by a qualified assessor (BCBA/BCBA‑D or state-defined equivalent).

• Affected procedure codes referenced in the policy include CPT 97151–97158, 0362T, 0373T and HCPCS H0031, H0032, H0046, H2012, H2014, H2019, S5110, S5111 (authorization implied when billing these codes).
• Behavior assessments and related assessment components must be completed by a Board Certified Behavior Analyst (BCBA/BCBA‑D) or other duly certified, licensed or registered equivalent as defined by state law.

Authorization must include CDE, behavior assessments, and individualized treatment plan with hours justification

Authorization submissions must include the CDE (meeting tool and recency requirements), behavior assessments, and an individualized treatment plan with documentation justifying the number of requested hours and the plan for their use.

• Include CDE documentation that demonstrates DSM diagnosis, severity level, intellectual/language status, evaluator credentials, test scores, and at least one primary clinician tool plus one parent/caregiver tool.
• Provide behavioral assessment results (maladaptive and skills acquisition assessments) with visual representations (graphs/tables) and documentation of direct observation/measurement.
• Treatment plan must state number of hours requested with clinical rationale tied to impairment, treatment history, and how additional hours will be used; include BCBA and caregiver signatures and coordination of care documentation.

Coordinate ABA with other therapies and document multidisciplinary coordination

Coordinate ABA with other therapies — ABA does not preclude PT, OT, medication management, or other interventions; document coordination of care as part of the treatment plan and authorization materials.

• Documentation should identify alternative providers responsible for services and include dates/outcomes of coordination efforts.
• When justifying intensity, documentation must address time in other therapies and multidisciplinary input supporting the requested hours.

Telehealth may supplement in‑person ABA; modality choice must be individualized

Telehealth may be used to supplement in‑person ABA services but is not intended to replace in‑person delivery when clinically indicated; choose modality individualized to member needs and adhere to CASP telehealth parameters and state allowances.

• Document rationale for use of telehealth vs. in‑person services based on individual needs, caregiver availability, and environmental supports.
• Refer to state-specific allowances and the CASP Practice Parameters for Telehealth when delivering ABA via telehealth.

No explicit step therapy; intensity/hours require clinical justification

There is no explicit step‑therapy sequence required by this policy; however, requested intensity and hours must be clinically justified in authorization materials.

• Policy emphasizes individualized intensity determination rather than mandatory stepwise progression of services.
• Requests for higher intensity must meet the policy's documentation and justification criteria.

Required diagnostic documentation: CDE with clinician and caregiver tools and recency rules

Diagnostic documentation must include a Comprehensive Diagnostic Evaluation (CDE) that documents DSM diagnosis, severity level, associated intellectual/language status, direct observation, caregiver interview, evaluator credentials, test scores, and at least one primary clinician tool plus one parent/caregiver tool.

• CDE must include developmental history, presenting concerns, evaluator summary for each instrument, test scores and dates, evaluator name/signature/credentials, and evidence the diagnosis is based on the CDE.
• If the CDE is >3 and <5 years old, submit a diagnostic interview within 12 months that includes specified elements (reason for services, mental status exam, DSM diagnosis, psychiatric history, medications, risk assessment, family support, areas for improvement, strengths/abilities, medical history).

Treatment plan documentation: BCBA and caregiver signatures, measurable goals, crisis plan, and hours justification

Treatment plans must include BCBA signature/credentials and caregiver signature, individualized measurable goals with baselines and mastery criteria, a dedicated crisis plan, coordination of care, and justification for number of treatment hours.

• Goals must be individualized, measurable, include baselines and mastery criteria for skill acquisition and behavior reduction, and be developed with caregivers and community providers as applicable.
• School‑based plans must document hours, target behaviors with objective measures, titration plans, and behavior reduction graphs when applicable.

Continuation documentation: updated assessment, attendance, and caregiver participation required

For continuation authorizations, submit an updated behavior assessment at least every six months, documentation of session attendance and caregiver participation, and evidence of progress or identified plan modifications if progress is limited.

• Updated behavior assessment must meet the policy assessment criteria and be completed ≤6 months for continuation.
• Document percentage of scheduled sessions completed; if attendance falls below 80% provide supporting documentation explaining barriers and actions taken to address them.

Assessment and treatment documentation must follow CPT descriptions and include objective data

Assessment and treatment records should align with the CPT/037x code descriptions and include objective measurement, functional analysis, and ongoing data (graphs/tables) to support clinical decisions and authorization requests.

• Document components described for 97151–97158, 0362T, 0373T as applicable (behavior identification assessment, supporting assessments, protocol modifications, family guidance).
• Include visual representations of assessment and progress data to support authorization and continuation requests.

Core ABA documentation elements required in assessments and plans

Documentation must reflect core ABA practice elements: objective assessment, understanding behavioral context and value, dignity promotion, behavior‑analytic methods, and consistent ongoing data collection and analysis informing treatment.

• Include comprehensive baseline assessment, small-step teaching units, consistent implementation across environments, and frequent plan adjustments based on data.
• Ensure caregiver training and supervision infrastructure are documented as part of the plan.

CDE must include at least one clinician and one parent/caregiver assessment tool

CDE submissions must include at least one primary clinician assessment tool and one parent/caregiver tool from the policy's enumerated lists (e.g., ADOS-2, CARS-2, ASRS, SRS-2) or other evidence‑based instruments documented in the report.

• Ensure the report identifies each assessment instrument, scores and dates, and includes the evaluator's summary and credentials.
• If Vineland is used for parent report, include an additional direct skills assessment per policy guidance.

Required treatment plan elements: crisis plan, transition/discharge planning, and caregiver training goals

Individualized treatment plans must contain a crisis plan, transition and discharge planning (including titration goals and step‑down plans), and 2–4 parent/caregiver training goals with a plan for caregiver training (ideally ≥2 hours/month) documented.

• Parent/caregiver training goals must include baseline data, expected behavior, and mastery criteria; document family participation or attempts to engage caregivers.
• Transition planning must outline specific titration goals and recommended services available on discharge.

Behavior assessment provider and method requirements: BCBA (or state‑equivalent) & continuous/discontinuous procedures

Behavior assessments (maladaptive and skills acquisition) must be completed by a BCBA/BCBA‑D or other certified/licensed equivalent as defined by state law and must include direct observation and measurement using continuous and discontinuous procedures.

• Assessments must include record review, interviews, rating scales, and direct observation using continuous (every occurrence/duration) or discontinuous (interval sampling) procedures.
• Provide visual representations (graphs/tables/grids) of assessment results and indicate instruments used (e.g., VBMAPP, ABLLS‑R, AFLS) as applicable.

Discontinuation triggers: no progress ≥6 months, provided for convenience, or achieved outcomes

Services may be discontinued or transferred when there has been no clinically significant progress for at least six months, when treatment is provided for convenience, or when the member has achieved desired outcomes; document updated assessment findings to support discontinuation or transfer decisions.

• If no measurable improvement for ≥6 months and revision is unlikely to produce progress, consider discontinuation or transfer and document reasoning and assessment data.
• Discontinuation may also be appropriate if services are in lieu of school/respite or provided for convenience rather than clinical need.

Excess hours require clinical justification for >6 hours/day or >30 hours/week

Requests exceeding customary intensity (over 6 hours per day or 30 hours per week) require clinical documentation that demonstrates necessity, details how additional hours will be used, and includes multidisciplinary coordination as applicable.

• Clinical documentation must show that needs cannot be addressed at lower intensity due to severity, frequency, or complexity across settings (e.g., persistent/severe challenging behaviors, limited functional communication).
• Provide a clinical rationale describing increased instructional trials, more practice opportunities, enhanced behavior reduction interventions, and evidence of multidisciplinary support.

Noncompliance risk: missing required diagnostic/assessment/treatment plan documentation may lead to denial

Failure to provide the policy‑required diagnostic, assessment, or individualized treatment plan documentation (including CDE, behavior assessments, and required treatment plan elements) may result in services not meeting policy requirements and potential denial.

• Ensure CDE, behavior assessment(s), and treatment plan include all specified components and signatures per policy to avoid noncompliance.
• Incomplete documentation of assessments, goals, caregiver training, or coordination of care may lead to services not meeting authorization criteria.

Denial risk for excessive requested hours without clinical justification

Requests that exceed six hours per day or 30 hours per week without the required clinical documentation justifying higher intensity (per policy criteria) may be denied.

• Denial risk increases when the submission lacks data demonstrating why lower intensity would be insufficient or lacks multidisciplinary coordination documentation.
• When claiming higher intensity, include signatures on revised plan, detailed clinical rationale, and evidence of how additional hours will target specific goals.

Insufficient attendance documentation (<80%) risks continuation denial without justification

If documented attendance of scheduled sessions falls below 80% during an authorization period and no explanatory documentation is provided (medical/educational/family barriers and actions taken), continuation at the previously approved level may be at risk.

• When attendance <80%, submit supporting documentation that explains barriers and demonstrates actions taken to address them to justify continuation.
• Document caregiver participation and family engagement efforts; lack of caregiver implementation may prompt consideration of alternative modalities.
