CPT 97155 protocol modification note documentation
Document what was modified and why, so 97155 protocol modification isn't downcoded to 97153.
Who it's for: BCBAs and BCaBAs billing 97155 protocol modification with or alongside direct treatment.
97155 gets downcoded when the modification isn't visible
CPT 97155 covers the BCBA modifying the treatment protocol, often while directing or working alongside the technician. The reimbursement reflects clinical decision-making — not direct implementation.
When the note reads like a 97153 direct-service note, payers downcode it: there's no documented modification, so there's nothing to support the higher-complexity code. The fix is making the modification and its rationale unmistakable in the record.
How BxScribe surfaces the protocol modification
The 97155 note structure puts the clinical decision — what changed and why — at the center of the record.
- 1
State the protocol before the session
Briefly document the targets and procedures as they stood, so the change has a clear reference point.
- 2
Document what you modified
The specific change you made — to a target, a procedure, a prompting strategy, a reinforcement schedule — stated concretely.
- 3
Give the clinical rationale
Why you made the change: the data, the client response, or the barrier that drove the decision. This is what distinguishes 97155 from 97153.
- 4
Record the response and next step
How the client responded to the modified protocol and what you'll monitor next.
