Applied Behavior Analysis (ABA) — Coverage Criteria
Defines medical necessity, eligible diagnoses, covered ABA services, provider qualifications, settings, coding, and benefit application for ABA services under the payer's policy. Affects providers delivering ABA and payers/members subject to the plan's stipulations.
Added CPT code 97152 for behavior identification supporting assessment administered by one technician under direction of a physician or other qualified health care professional to the Coding list.
Modified Benefit Application statements to account for additions of CPT codes and scope changes for technician-administered assessments and multiple-family groups.
Remote/telehealth provision of supervision and all ABA services is allowed at any time without restrictions.
Coverage and Medical Necessity Criteria
Medical Necessity Criteria
Covered when ALL of the following are met
ABA is considered not medically necessary for other diagnoses.
Services must be consistent with the Coding section.
Direct treatment may be delivered by supervised behavioral technicians, BCaBAs, or supervised master's/doctoral clinicians consistent with scope of practice and state law.
Direct school services must consist entirely of bona-fide ABA treatment activities; other school activities are not medically necessary.
Benefit Application / Medical Necessity Rules
Covered and not medically necessary conditions and limits for ABA services:
Exceptions only as specified by plan stipulations or explicit short-term specialized services.
Group treatment sessions are covered for only one clinician per identified individual regardless of how many clinicians are present.
Some items may be contract exclusions depending on member contract language.
Schools, specialized school tuition, and school programs (including services that are the responsibility of a school district) are non‑covered under the ABA benefit except when a covered ABA provider delivers bona‑fide ABA direct treatment activities in the school setting. Camps, day camps, summer camps, and recreational programs are non‑covered because these activities are primarily recreational and do not represent continuation of an individual’s ABA treatment plan or targeted treatment goals. Refer to member contract stipulations for any plan‑specific exceptions.
Time spent providing training of staff (distinct from supervision), preparation work prior to service delivery, and accompaniment/transportation to appointments or activities when the clinician is not actively providing treatment are not considered ABA services and are non‑covered or not medically necessary. Accompaniment or transport may be covered only when the identified individual has a documented pattern of significant behavioral difficulties for that activity and the clinician is actively delivering treatment during the activity rather than merely supervising or containing the individual.
The policy lists explicit exclusions and non‑ABA activities that are not covered as ABA services. Examples include: training of behavioral technicians/assistants or BCaBAs (distinct from supervision), preparation work before sessions, accompanying individuals to non‑treatment activities unless active treatment is provided, transporting the member in lieu of family (except when active treatment during transport is required), assisting as a tutor or school aide (unless significant behavioral difficulty is documented), provider travel time, babysitting/respite, provider residing in the home as live‑in help, peer‑mediated groups, training/classes for groups of parents of different individuals, general parenting coaching, hippotherapy/equestrian therapy, pet therapy, auditory integration therapy, sensory integration therapy, and visual field analysis. Some items may also be contract exclusions depending on plan language.
Applied Behavior Analysis (ABA) is considered medically necessary only for individuals with a documented diagnosis of Autism Spectrum Disorder (DSM‑5/DSM‑5‑TR or equivalent ICD‑10 diagnoses). Provision of ABA services for diagnoses other than Autism Spectrum Disorder is explicitly stated as not medically necessary.
Direct ABA treatment provided to more than one identified individual in the same treatment session is not medically necessary except when the session is a bona‑fide group treatment session as defined by the policy. Family therapy or collateral sessions that focus on a single identified individual and multiple‑family group sessions without the patients present are separate exceptions; treating siblings together is not considered medically necessary unless the session meets the bona‑fide family therapy or covered group session definitions.
Having more than one program manager/lead behavioral therapist, more than than one clinician providing direct ABA treatment, or more than one provider group/agency providing ABA for the same individual during the same episode is considered unnecessary duplication and is not medically necessary, except for narrowly defined, time‑limited, highly specialized services (for example, a short‑term intensive feeding program) that the primary provider cannot reasonably provide.
Applied Behavior Analysis (ABA) Coverage Details
ABA-specific coverage
ABA is covered when delivered for Autism Spectrum Disorder by qualified providers and includes the following services:
Refer to the Coding section for specific code mapping and to Behavior Analyst Certification Board guidance for intensity recommendations.
Clinical delivery and modality notes
Clinical considerations and service delivery modalities:
Policy update made telehealth allowance permanent effective 01/01/23.
Prior limits on number of daily group sessions were removed.
Outpatient / community / school (limited)
Documentation must demonstrate ASD diagnosis per DSM-5/DSM-5-TR or equivalent ICD-10 codes and be made by a clinician permitted to diagnose psychiatric or neurodevelopmental disorders.
Refer to Behavior Analyst Certification Board guidance for intensity and supervision recommendations.
Outpatient
Some direct services may occur in school only when bona-fide ABA activities are provided.
Agencies must meet provider requirements to be considered ABA treatment service providers.
Service Delivery and Telehealth
ABA (in-person and telehealth)
Supervision of staff may be provided in-person or via telehealth.
Telehealth / Virtual ABA
Telehealth may require increased caregiver coaching for some patients and can improve access for individuals in areas without in-person services.

Provider Requirements, Documentation, and Billing Guidance
Required Codes for Reimbursement
In-network providers must use the CPT/HCPCS codes listed in the Coding section above to be reimbursed for ABA services. Services not listed in the Coding section are not covered.
Prior Authorization / Coding Updates
Prior authorization and prior-auth processes should reflect the current coding list. CPT codes 97152 (behavior identification supporting assessment by a technician) and 97157 (multiple-family group adaptive behavior treatment guidance) have been added to the Coding section and should be included in authorization workflows and any related utilization review checks.
Coding-Aligned Documentation
Documentation must support the use of the specific CPT/HCPCS codes billed. Records should include the Functional Behavioral Assessment (FBA) or supporting assessment, treatment plan content and updates, and contemporaneous direct treatment notes that justify billed services and time units.
- FBA reports and periodic reassessments tied to coded assessment services (e.g., 97151/97152, HCPCS H0031).
- Treatment plan development/revision documentation supporting H0032 or equivalent codes.
- Direct treatment notes documenting activities, behavior targets, time increments, and clinician role when billing time-based codes (e.g., 97153–97158, H2014, H2019).
Required Documentation Elements
Documentation must include specific required elements: the provider’s role and scope of practice; date and type of assessment (initial FBA or reassessment) and frequency of FBAs; treatment plan goals, measurable objectives, and justification for modality/intensity; clinician credentials and licensure; supervision notes when applicable; and clear linkage between billed units and contemporaneous progress or data analysis.
- Provider role and scope (program manager/lead behavioral therapist, BCBA, technician, etc.).
- FBA frequency, date of initial FBA, and dates of reassessments (no more frequently than every 6 months unless clinically justified).
- Treatment plan development and revisions with measurable goals and planned interventions.
- Direct treatment notes with date/time, duration, activities, behavior targets, outcomes, and who delivered the service.
- Supervision documentation when program manager/lead behavioral therapist supervises technicians during direct treatment.
Scope-of-Practice Denial Risk
Assessments or supporting assessments performed by behavioral technicians/therapy assistants/paraprofessionals are non-covered unless those activities are included within their legally permitted scope of licensure. Providers should ensure assessments are performed only by clinicians whose scope allows it to avoid scope-of-practice denials.
- Do not bill technician-administered assessments unless state scope permits and documentation supports the scope.
- Program managers/lead behavioral therapists or other licensed clinicians must perform or sign off on required assessments when technician scope is limited.
Triggers for Denial / Duplication of Services
The following situations are common triggers for denial. Avoid duplicative billing or multiple clinicians billing for the same individual/session; ensure only one program manager/lead behavioral therapist is billed for an individual at a time; do not bill multiple providers or multiple clinician types simultaneously for the same direct treatment time; and do not bill individual treatment when the clinician was not exclusively working with the member for the entire billed time in a group setting.
- More than one program manager/lead behavioral therapist billed for the same individual during the same time/episode.
- More than one clinician billed for direct ABA treatment to the same individual at the same time.
- Multiple provider groups/clinics billing for the same individual concurrently (unless an approved short-term specialized service exception applies).
- Billing individual treatment while the individual was in a group setting and the clinician was not exclusively working with that individual for the full billed time.

Key Definitions
Background
Applied Behavior Analysis applies principles of learning — manipulating antecedents and consequences — to change behavior and target impairments associated with Autism Spectrum Disorder. In the autism context ABA is used to increase communication, attention, social and adaptive skills, and to reduce behaviors that interfere with learning and functioning. ABA services include functional behavioral analyses (initial and periodic), individualized and group treatment, and caregiver education, training, coaching, and support, together with non‑treatment components such as case review, data analysis, coordination with other providers or schools, supervision, and treatment plan development or revision. The policy references Behavior Analyst Certification Board guidance for recommendations on treatment intensity and supervision.
