90837: Individual psychotherapy, 60-minute session
90837 reports individual psychotherapy with the patient for a session of 53 minutes or longer. It pays more than the 45-minute code, is frequently reviewed for clinical justification, and is the most common source of behavioral health downcoding.
What it covers
The 53-minute floor is a therapy-time threshold, not an appointment length. Sessions are documented with either start and stop times or a stated total, and the note should make clear why an extended session was clinically indicated rather than habitual.
Several payers monitor the ratio of 90837 to 90834 across a provider's panel. A high proportion is not itself improper, but it is the pattern that generates records requests, and practices that cannot produce time documentation lose the difference retroactively.
When to use it
- Sessions where therapy time reaches 53 minutes or more
- Trauma-focused or exposure-based modalities that require an extended session to be delivered safely
- Crisis-adjacent presentations requiring extended stabilization within a scheduled session
Where the boundary sits
| Compared with | The deciding rule |
|---|---|
| 90834 | Below 53 minutes of therapy time, 90834 applies regardless of how the appointment was scheduled. |
| 90833 | When an E/M service is also delivered, psychotherapy is reported as an add-on rather than as a standalone session code. |
Documentation that keeps it paid
- Start and stop times, or an explicit total therapy time
- The clinical reason the extended length was indicated
- Modality, interventions delivered, and response
- Progress against documented treatment plan goals
Denial & audit triggers
Downcoding to 90834
The most common outcome, and it arrives as a reduced payment rather than a denial. Without line-level payment comparison against the contracted rate, it is invisible.
Utilization review on frequency
A high 90837 share triggers records requests. The defence is time documentation and clinical rationale in every note, created contemporaneously.
Authorization thresholds
Some plans authorize a set number of sessions and require review to continue. Sessions delivered past the authorized count are generally not recoverable.
How it pairs with other codes
- Not reported with 90834 for the same session
- Not reported alongside an E/M by the same clinician for the same encounter — use the add-on structure instead
- Family or group therapy on the same day follows separate payer rules and often requires review
Questions we get asked
- What is the minimum time for 90837?
- 53 minutes of therapy time with the patient. Below that, 90834 applies.
- Why do payers scrutinize 90837?
- It pays materially more than the 45-minute code and the only distinguishing element is documented time, which makes it both easy to over-report and easy for a payer to reduce on review.
- Can 90837 be delivered via telehealth?
- Widely, yes, with the appropriate modifier and place of service. Audio-only coverage varies by plan and state and changes more often than audio-video policy.
Reference only, and typical rather than universal: coverage, modifier requirements, and payment vary by payer, plan, state, and provider type. Confirm current payer policy before billing.
