ABA billing · Updated August 2026
ABA billing built around authorizations, not just claims
Most ABA denials are decided before the claim is ever submitted. We work the front of the cycle — units, authorizations, rendering providers and supervision rules — then chase what still gets denied.
Recura Health provides outsourced ABA billing for independent practices: unit-level authorization tracking, CPT 97151–97158 coding, claim submission, denial management and AR follow-up inside CentralReach or your existing system. Pricing is 4–8% of net collections. The service is built for practices with one to ten providers and $500k–$5M in annual collections.
How do you reduce an ABA claim denial rate?
Behavioral health denial rates run roughly 12–20% against 5–10% for medical and surgical claims. In ABA specifically, the causes cluster into four preventable failures — none of which a generalist biller is watching for.
Authorizations tracked by date, not by unit
An authorization approves a number of units, not a window of time. Practices that track only the expiry date discover the overage after delivering unbillable sessions. We track remaining units per client per code and flag reauthorization before the balance runs out.
Rendering provider and supervision mismatches
97153 is delivered by a technician under QHP direction; 97155 is delivered by the QHP with protocol modification. Billing the wrong rendering provider against the wrong code is a clean denial every time, and payers vary in how they want supervision documented.
Time-based unit errors
Adaptive behavior codes bill in 15-minute increments, and a unit requires at least the 8-minute midpoint. Session notes that do not carry defensible start and stop times turn into unit disputes on audit, and into denials in the meantime.
Carve-out routing errors
The member's card says one payer; behavioral health is administered by another. Claims sent to the medical payer instead of the managed behavioral health organization — Optum Behavioral Health, Carelon Behavioral Health, Magellan Healthcare — deny for reasons that look like eligibility problems and are not.
What are the ABA CPT codes for 2026?
Adaptive behavior services sit in the CPT 97151–97158 range. Every treatment code is time-based in 15-minute increments, and a billable unit requires at least 8 minutes of that increment.
| Code | Service | Delivered by | Unit |
|---|---|---|---|
| 97151 | Behavior identification assessment | Qualified healthcare professional, face-to-face with client | 15 min |
| 97152 | Behavior identification supporting assessment | Technician under QHP direction | 15 min |
| 97153 | Adaptive behavior treatment by protocol | Technician under QHP direction, one patient | 15 min |
| 97154 | Group adaptive behavior treatment by protocol | Technician, two or more patients | 15 min |
| 97155 | Treatment with protocol modification | QHP, may include simultaneous direction of technician | 15 min |
| 97156 | Family adaptive behavior treatment guidance | QHP, with or without client present | 15 min |
| 97157 | Multiple-family group guidance | QHP, without clients present | 15 min |
| 97158 | Group treatment with protocol modification | QHP, two or more patients | 15 min |
Payer policies layer their own limits on top of the code set — daily unit caps, concurrent billing restrictions between 97153 and 97155, and modifier requirements that differ by plan. Code definitions are stable; payer rules are not, which is the part that has to be actively maintained rather than learned once.
What we take on
Eligibility & benefits
Verified before intake, including whether behavioral health is carved out and to whom, plus deductible and copay position.
Prior authorization
Initial requests, concurrent reviews, and reauthorization tracked against remaining units rather than calendar dates.
Coding & charge entry
Session notes to claims, with unit maths checked against documented start and stop times before submission.
Claims & clearinghouse
Submission and rejection handling in CentralReach, Office Ally or Availity, with clean-claim rate tracked weekly.
Denial management
Root cause by payer and by code — not blind resubmission. Appeals written by people, with the clinical documentation attached.
AR follow-up
Aged AR worked oldest-first by payer, with the calls placed during US payer hours rather than overnight.
Common questions about ABA billing
What does ABA billing cost for a small practice?
Outsourced ABA billing generally runs 4–8% of net collections, or roughly $2–8 per claim on a flat-fee model. We price on collections with a monthly floor. Practices under about $300,000 in annual collections are usually better served by a part-time in-house biller, and we will say so rather than sell you something that will not pay for itself.
Do you work inside CentralReach?
Yes — CentralReach, and also SimplePractice, Qualifacts, Netsmart, Office Ally and Availity. We work in your system rather than moving you onto ours. There is no platform migration, and no lock-in that makes leaving us expensive. If the relationship stops working, your data and your workflows are where they always were.
How long does the transition take?
Thirty days, run in parallel. Your existing process keeps operating while we take over payer by payer, so there is no window where claims are nobody's responsibility. Aged AR is not abandoned at handover — it is worked alongside current claims, and it is usually where the first recovered dollars come from.
What happens to authorizations already in flight?
They are audited first. The opening task in every engagement is a unit-level reconciliation of every active authorization: what was approved, what has been delivered, what has been billed, and what is at risk of expiring unbilled. This routinely surfaces sessions already delivered that were never claimed.
Authorizations
Tracked by unit, never by date
An authorization approves a number of units, not a window of time. We reconcile every active authorization at unit level — approved, delivered, billed, and at risk — and trigger reauthorization on the balance rather than the calendar.
