ABA therapy billing services for behavior analysis practices
Fastora provides ABA therapy billing services for applied behavior analysis practices, from single-BCBA clinics to group practices with clinic, home and school-based programs. ABA claims are built on hours of approved treatment, billed in 15-minute units by code, and tied to who delivered each minute: a registered behavior technician, a BCBA, or both at once.
That makes ABA billing more like managing a time budget than billing a visit. A child may be approved for a set number of weekly technician hours plus supervision and caregiver training hours, and every session draws down a specific bucket. When the schedule and the authorization drift apart, the result is unpaid hours that cannot be recovered.
Our ABA billing services cover eligibility and benefits, authorization tracking, charge review, our Advanced Pre-Submission Claim Review before electronic submission, payment posting, denials and AR follow-up. Every claim is handled by certified medical billing and coding professionals. ABA sits within our wider behavioral health billing work.
ABA billing codes and rules specific to adaptive behavior services
Adaptive behavior services use CPT Category I codes 97151 through 97158, plus two Category III codes, 0362T and 0373T, for patients with severe destructive behavior. All are reported in 15-minute units. CPT's general time rule treats a unit as reportable once the midpoint is passed, but payers may set their own rule, so we follow each plan's policy.
| Code | Descriptor (summary) | Who delivers it |
|---|---|---|
| 97151 | Behavior identification assessment, each 15 minutes, including face-to-face assessment and non-face-to-face analysis and report/treatment plan preparation | Physician or other qualified health care professional (QHP), such as a BCBA |
| 97152 | Behavior identification-supporting assessment, face-to-face with the patient, each 15 minutes | One technician under the direction of the QHP |
| 0362T | Behavior identification supporting assessment for a patient with destructive behavior, with two or more technicians, QHP on site, in a customized environment, each 15 minutes | Technicians, with the QHP on site |
| 97153 | Adaptive behavior treatment by protocol, face-to-face with one patient, each 15 minutes | Technician under the direction of the QHP |
| 97154 | Group adaptive behavior treatment by protocol, face-to-face with two or more patients, each 15 minutes | Technician under the direction of the QHP |
| 97155 | Adaptive behavior treatment with protocol modification, which may include simultaneous direction of a technician, face-to-face with one patient, each 15 minutes | QHP |
| 97156 | Family adaptive behavior treatment guidance, face-to-face with guardian(s)/caregiver(s), with or without the patient present, each 15 minutes | QHP |
| 97157 | Multiple-family group adaptive behavior treatment guidance, without the patient present, each 15 minutes | QHP |
| 97158 | Group adaptive behavior treatment with protocol modification, face-to-face with multiple patients, each 15 minutes | QHP |
| 0373T | Adaptive behavior treatment with protocol modification for a patient with destructive behavior, with two or more technicians, QHP on site, in a customized environment, each 15 minutes | Technicians, with the QHP on site |
The 97153 CPT code: direct treatment hours
Most authorized ABA hours are billed under 97153, the technician's one-on-one treatment by protocol. Session notes should show start and stop times, the setting, the targets run and the technician's name and credential, because 97153 usually carries the most units on an ABA claim and draws the most attention when a payer requests records.
The 97155 CPT code: protocol modification and supervision
97155 covers the BCBA's face-to-face work to adjust the protocol, which may include directing the technician during the session. CPT allows 97155 to be reported for the same time as 97153 when both clinicians are working with the patient, but some payers do not pay overlapping time or cap it as a share of direct hours. We set concurrent billing by payer policy before the first claim goes out.
Modifiers and upcoming code changes
Some Medicaid programs and health plans require modifiers such as HM, HN, HO or HP to show the education or credential level of the person who delivered the service, and others require the technician's own NPI as rendering provider. The ABA Coding Coalition has announced that the CPT code set taking effect January 1, 2027 revises the adaptive behavior codes, including new codes, a split of 97155 and deletion of 0362T and 0373T. Payer adoption can lag, so we confirm each plan's policy before billing under the new set.
Authorizations, treatment plans and hour tracking
Most commercial plans and Medicaid programs require prior authorization for ABA. A typical request includes the autism diagnosis from a qualified clinician, the 97151 assessment results, a treatment plan with measurable goals, and the hours requested by code. Approvals are usually time-limited, and reauthorization needs updated assessment data and progress toward goals.
- Approved hours are recorded by code, by week where the plan sets weekly limits, and by date range.
- Scheduled hours are compared with remaining approved units so overruns are caught before the session, not after the denial.
- Reauthorization dates are flagged early enough for the BCBA to complete a new assessment and progress report.
- Changes in setting (clinic, home, school or telehealth) are checked against what the authorization covers.
Our prior authorization service submits requests and tracks approvals, so the clinical team spends its time on treatment plans rather than payer portals.
Texas Medicaid ABA billing
Texas Medicaid added applied behavior analysis as a benefit effective February 1, 2022, for members under 21 with autism spectrum disorder. Prior authorization is required, and services are billed either to TMHP for fee-for-service members or to the member's Medicaid managed care organization.
Provider type, enrollment, documentation and supervision requirements are set out in the autism services section of the Texas Medicaid Provider Procedures Manual, and each managed care plan publishes its own authorization steps. Texas also licenses behavior analysts through the Texas Department of Licensing and Regulation, so licensure is checked alongside BACB certification. Practices outside Texas face their own state Medicaid rules, which we review state by state.
ABA credentialing for BCBAs and RBTs
ABA credentialing covers more than the supervising analyst. BCBAs need an NPI, BACB certification, any required state license, a CAQH profile where payers use it, and enrollment with each plan. Depending on the payer, technicians may need their own NPI, enrollment or registration as rendering providers before their 97153 time can be billed.
Supervision is part of billing compliance too. Under the BACB's RBT requirements, technicians must receive ongoing supervision for a minimum share of their service hours each month, and payers may set stricter ratios. The BACB updated its RBT requirements for 2026, so we confirm the current handbook and each payer's policy when setting up supervision tracking.
Our credentialing and enrollment team tracks each application through a nine-stage process, from document collection and NPI and CAQH setup to final approval, and flags new hires so they are not scheduled with a payer before their effective date.
Common ABA denials and how we prevent them
| Denial cause | Prevention step |
|---|---|
| Units beyond authorized hours | Hours tracked by code and week; schedules checked against remaining units |
| No authorization on file or expired approval | Reauthorization flagged before the end date; approval number attached to every claim |
| Rendering provider not enrolled or credential missing | Technician and BCBA enrollment confirmed before scheduling |
| Missing or wrong credential modifier | Modifier rules set by payer at charge entry |
| Overlapping 97153 and 97155 time not allowed | Concurrent billing applied only where the payer permits it |
| Units not supported by session notes | Start and stop times and session content checked before submission |
Each denial is logged by reason code and payer through our denial management service, corrected or appealed with the treatment plan and session data, and traced back to the step that caused it. Open claims are worked by payer and age before filing deadlines pass.

ABA billing company: insurance billing for ABA therapy
An ABA billing company handles what generalist billers often miss: the 97151–97158 code family, session authorizations with hour caps, school-based versus clinic-based place of service, and commercial-plan ABA carve-outs with their own rules. ABA insurance billing means eligibility checks against the behavioral administrator — not just the medical plan — visit authorization tracking against approved hours, and claims that carry the right rendering provider for BCBAs and RBTs. Miss any one of those and the claim denies even when the session was medically necessary. Our behavioral health billing page covers the related authorization workflows.
ABA RCM: the full cycle behind the claims
ABA RCM adds the upstream work that decides whether claims pay: benefits verification against the carve-out plan, authorization management by hour count, credentialing for each BCBA and technician, and denial follow-up on the authorization denials ABA practices see most. It is the difference between a billing vendor that submits claims and a revenue cycle that protects the hours you are approved for. Our credentialing and enrollment team handles BCBA and technician panels and our prior authorization service tracks authorized hours.
