Units Exhausted Mid-Period
Therapy continuing after the approved unit balance is used, leaving sessions unpaid.
The fixTrack remaining units weekly and alert clinical staff before the balance runs low.
Authorised units tracked, rendering provider always correct
Applied behaviour analysis is billed in units against an authorisation that runs out quietly. Deliver a session past the approved balance and it is unpaid, no matter how clinically necessary it was. Add technicians and supervisors delivering different services in the same visit, and the record has to be exact. We track units and rendering providers so nothing is delivered unfunded.
ABA therapy billing covers applied behaviour analysis services, most often for autism spectrum disorder. It includes initial assessment, treatment planning, direct therapy delivered by technicians, and supervision or protocol modification by an analyst.
Everything runs on units. Payers approve a specific number of units for a specific period, split between assessment, direct treatment, and supervision. Those buckets are usually separate and do not transfer between each other.
The second variable is who delivered the service. Technician-delivered therapy and analyst-delivered supervision are different codes at different rates, and the claim must reflect the person who actually provided the care in that session.
The clinical plan and the funded plan are two different things, and only one of them pays.
Assessment, direct treatment, and supervision are usually authorised separately and cannot be transferred.
Technician-delivered and analyst-delivered services use different codes and pay at different rates.
Continuing authorisation depends on progress data submitted before the current period ends.
Supervision provided while a technician works has specific documentation expectations.
Nearly all of them involve units or who delivered the service.
Therapy continuing after the approved unit balance is used, leaving sessions unpaid.
The fixTrack remaining units weekly and alert clinical staff before the balance runs low.
Sessions billed under the analyst when a technician delivered the direct therapy.
The fixCapture who delivered each session at the point of documentation.
Supervision units billed against a treatment authorisation that does not cover them.
The fixBill each service against its own authorised bucket, never a shared pool.
Renewal requests submitted after the authorisation lapsed, creating a gap in funded care.
The fixStart the reassessment several weeks before the current period expires.
Renewals denied because the submission did not show measurable progress toward goals.
The fixReport objective goal data at every reassessment, not narrative summaries.
Units calculated from scheduled time rather than actual documented session minutes.
The fixConvert units from recorded start and stop times on every session note.
Built around the authorisation, which governs everything.
Benefits are checked and the initial assessment authorisation is obtained before any service begins.
Approved units are recorded by category so each service is billed against the right authorisation.
Remaining units are monitored every week and clinical staff are warned before a balance runs low.
Each session is matched to the person who delivered it, so the correct code and rate apply.
Renewal requests go out with objective goal data well before the current period expires.
Claims transmit regularly, with reporting showing authorised units against units actually delivered.
Assessment and treatment authorisations handled together.

| 97155 | Protocol modification by the analyst |
| 97156–97157 | Family and group guidance services |
| 97158 | Group adaptive behaviour treatment |
| Group | Clinical Focus |
|---|---|

| R62.0 | Delayed developmental milestones |
Note: This is general education on how aba therapy coding is organised. Code sets and payer policies change often. Always check the current code set and the payer's active policy for the date of service.

Practical answers for ABA providers and agencies.
Track the remaining unit balance weekly and warn clinical staff before it runs low. ABA authorisations approve a fixed number of units, and sessions delivered beyond that are almost never recoverable on appeal. Because schedules are set in advance, a balance can be consumed faster than anyone notices. A weekly figure in front of the clinical team prevents it.
Because the rendering provider is recorded at billing rather than at documentation. Direct therapy delivered by a technician and protocol modification by an analyst are different codes at different rates. Reconstructing who was in the room afterwards is unreliable and creates repayment risk. Capturing it on the session note makes the claim correct automatically.
No. Authorisations generally approve separate buckets for assessment, direct treatment, and supervision, and they do not transfer between categories. Billing supervision against a treatment authorisation produces a denial even when units remain overall. We load each bucket separately so services are always billed against the authorisation that actually covers them.
Several weeks before the current authorisation expires. Renewals require submitted progress data and payer review time, and any gap between periods means unfunded care or an interruption in the child's treatment. Starting late is the most common cause of both. We prompt the reassessment early enough that the new period begins without a break.
Objective measurement against the treatment plan goals, not a narrative description of how the child is doing. Reviewers look for baseline figures, current figures, and movement toward defined targets. Submissions describing engagement or effort without numbers are the ones that get denied. Structured goal data makes renewals far more predictable.
From documented start and stop times, never from the scheduled appointment length. Sessions run short for many legitimate reasons, and billing the scheduled duration overstates units in a way that invites recoupment. Recording actual times protects the claim and gives you defensible evidence if utilisation is ever reviewed by the payer.
Often yes, depending on the payer and the state. Some plans require technicians to be individually registered or linked to a supervising analyst before their services can be billed. Delivering therapy before that linkage exists produces denials on every session. We confirm requirements per payer and hold claims until the linkage is active.
As protocol modification by the analyst, with documentation showing what the analyst actually did. Being present is not the same as delivering a billable service. The note needs to record the clinical work performed, such as adjusting a protocol or training the technician on a change. Vague presence notes do not support the claim.
Yes, though they may fall under different funding. Services delivered in schools are sometimes covered by an education programme rather than health insurance, which changes who pays and what documentation is required. We identify the funding source per setting rather than assuming health coverage applies to every location a child is seen in.
Authorised units against units actually delivered, by client and by period. That single view shows where care is at risk of running unfunded and where approved capacity is going unused. Both are problems. Most agencies discover under-utilisation only at renewal, when the unused units have already expired and cannot be recovered.
We review your authorisation balances against delivered sessions and show you where care is running ahead of funding, and where approved units are going unused.
