CPT code 90832: the short psychotherapy session
CPT code 90832 covers 16 to 37 minutes of individual psychotherapy. It is the shortest individual therapy code, and psychotherapy under 16 minutes is not billable at all. Under CMS guidance the code follows the documented time, so a session of 38 minutes or more moves up to 90834. Below is the full time rule, what the note has to show, and how 90832 sits next to 90833 and 90834, with the CMS source behind every rule.

What CPT code 90832 covers
Individual psychotherapy, 16 to 37 minutes. The shorter individual psychotherapy session.
90832 is the shorter individual psychotherapy session, roughly a half hour of therapy with your client. It sits at the bottom of the three time-banded individual codes, below 90834 and 90837.
The band is wider than the half-hour name suggests. Anything from 16 minutes up to 37 minutes of documented psychotherapy lands on 90832, so a session that ran short can still be billable as long as it crossed the 16 minute floor. Below that floor there is no individual psychotherapy code to bill at all.

90832 vs 90834: the 38-minute line
Document 16 to 37 minutes of psychotherapy and the session is 90832. Document 38 to 52 minutes and it is 90834. The code follows the documented time, not the scheduled slot, so a booked half hour that runs long can become 90834 on paper. Record start and stop times or the total time for every session and the choice makes itself.
90832 vs 90833: standalone vs add-on
90833 covers the same 16 to 37 minute band, but as an add-on billed alongside an evaluation and management (medical) service in the same visit. A standalone therapy session has no medical visit attached, so it bills 90832. If you do not bill medical visits, 90833 is not your code.

Why are there no reimbursement rates on this page?
Reimbursement varies by payer, locality, and year, so a single national number would be wrong for most readers. Check your payer contracts for your actual rates, or the CMS Physician Fee Schedule lookup tool for Medicare amounts in your locality.
