Billing 90837 Without Triggering a Recoupment

90837 represents a 60-minute psychotherapy session, and it is often the highest-value code a behavioral health practice bills routinely. That value is exactly why payers scrutinize it. When the code appears more often than a payer expects, the claims do not simply deny, they draw audits, and audits without airtight documentation end in recoupment.

The time band is the foundation. 90837 is defined against a 60-minute session, distinct from the 45-minute 90834, and the record has to make the session length unambiguous. Start and stop times, or a clearly documented duration, turn a defensible claim into a provable one. A note that gestures at time without stating it is a note that cannot survive review.

Documentation beyond duration carries the rest of the weight. The therapeutic interventions, the clinical rationale for the session length, and the treatment plan the session advances all belong in the record. Payers are not questioning whether therapy happened, they are questioning whether the level billed matches the work documented, and only the note can answer that.

A practice that bills 90837 heavily is not doing anything wrong, provided the records support it. The exposure comes from pattern without proof. Consistent, contemporaneous documentation is what lets a high-value code stay in your mix without becoming the reason a payer comes looking for money back.
