ABA reauthorization timelines
Start a reauthorization request at least 30 days before the current authorization ends — many providers work to 30–45 days — with updated progress data, revised goals, and the hours requested for the next period. The submission date, not the end date, is the deadline that protects continuity.

Reauthorization fails quietly: the current period ends on a date printed months earlier, and a request submitted the week before cannot be reviewed in time. The fix is not speed — it is treating the payer's lead time as a hard internal deadline, tracking authorized ABA units, and starting the next prior authorization request before the current approval closes.
A working timeline
| Days before period end | Action |
|---|---|
| 45 | Confirm the end date and unit balance; flag if utilization is far off pace |
| 30–45 | Assemble progress documentation and updated treatment plan; request family signatures |
| 30 | Submit the reauthorization request |
| 14 | Confirm receipt and completeness with the payer; answer pends within a day |
| 7 | Escalate if no decision; prepare the family for possible scheduling adjustments |
| 0 | New authorization active — record the new units and dates immediately |
Lead times differ by payer — some ask for 14 days, some for 60. Record each payer's stated lead time where your team will actually see it, and set the internal deadline a week earlier than theirs.
What payers expect in a reauthorization
- Progress against the current treatment plan's goals, with data — not narrative alone.
- Updated goals for the next period, reflecting what was mastered or revised.
- Utilization of the current authorization: units delivered against units approved, and any reasons for variance.
- The requested hours per billing code for the next period, justified by the progress picture.
- Current coordination-of-care information and any changes in school or other therapies.
A request for the same hours is not automatically justified by history. Reviewers compare progress data against the hours delivered; flat data with unchanged requests invites reductions. The strongest reauthorization tells the honest story the data supports — including when fewer hours are now appropriate. If the decision still comes back as an ABA authorization denied or reduced, respond to the payer's stated reason rather than guessing.
When a gap still happens
- Notify the family immediately and document the interruption — lapses affect continuity of care and sometimes school plans.
- Ask the payer whether expedited review is available given the lapse.
- Record the cause: late submission, pend, or payer delay. The pattern across cases tells you which process to fix.
Frequently asked questions
- When should I submit an ABA reauthorization?
- At least 30 days before the current authorization ends, or earlier when the payer's stated lead time is longer. Treat the submission date as the real deadline.
- What documentation does reauthorization need?
- Progress data against current goals, updated goals for the next period, utilization of the current authorization, the requested hours with justification, and current coordination-of-care details.
- What happens if reauthorization is late?
- Services delivered after the authorization end date are generally not covered until the new approval. Notify the family, ask about expedited review, and document the cause so the process improves.
- Can hours increase at reauthorization?
- Yes, when the progress data and the member's presentation support it. Requested hours — up or down — should follow the data, because reviewers compare the two.
