CPT Code 90834: How to Bill the 38–52 Minute Psychotherapy Session

CPT code 90834 is psychotherapy with the patient, and sometimes a family member, for 38 to 52 minutes. It is one of three timed individual psychotherapy codes. This guide shows when to bill CPT code 90834, how it differs from 90832 and 90837, and what the note has to show. It is written for psychotherapists and for psychiatrists.

For the full code-by-code reference, see our individual psychotherapy guide.

What CPT code 90834 means

CMS says “CPT Codes 90832-90838 represent psychotherapy. Psychotherapy without medical evaluation and management services are reported as 90832, 90834 and 90837” (CMS Coverage Database, Article A57480, WPS, rev. 1/1/2026). The AMA descriptor for 90834 is psychotherapy with the patient, 45 minutes as the typical time. Bill by the minute ranges below, not the typical time.

CPT code 90834 time range

Code	Service	Time range
90832	Psychotherapy, patient and/or family member	16–37 minutes
90834	Psychotherapy, patient and/or family member	38–52 minutes
90837	Psychotherapy, patient and/or family member	53 minutes or more

Contractor article A57520 (First Coast, rev. 1/1/2025) quotes the 90832 range. A session of 50 minutes is CPT code 90834. A session of 53 minutes is 90837. There is no separate code between them. Compare the two in our 90837 or 90834 guide.

What counts as time

CMS says “Psychotherapy times are for face-to-face services with the patient. The patient must be present for all or some of the service” (Article A57520). Start and stop times, or total times, must be documented for 90832, 90834 and 90837.

When CPT code 90834 is the wrong code

• Crisis session: CMS says not to bill crisis codes with 90832–90838. See the crisis psychotherapy guide.
• Intake: the diagnostic evaluation is 90791 or 90792, and NCCI does not allow psychotherapy codes with 90791 on the same date. See the CPT code 90791 guide.
• Medication management: CMS says psychotherapy codes should not be used as generic psychiatric service codes when an E/M or pharmacological management code fits better.
• Family session without the patient: use 90846. See the CPT code 90846 guide.

Who bills CPT code 90834

Psychotherapists: use 90834 for a 38–52 minute session where psychotherapy is the focus. Record the start and end time.

Psychiatrists: use 90834 only when the visit is psychotherapy without an E/M service. When you bill an E/M service the same day, psychotherapy is reported with an add-on code instead. See the psychotherapy add-on codes guide and the E/M and home-visit guide.

What to document

• Date of service, start time and end time
• The focus of the session and the treatment goal it supports
• Interventions used and the patient’s response
• The plan for the next session

See documentation requirements for the full list.

Frequency and long sessions

No annual cap appears in the contractor articles reviewed, and medical necessity governs. A session over 90 minutes is paid only if the record shows the face-to-face time and the medical necessity for the extra time (CMS Coverage Database, Article A57480). Private payers and state Medicaid programs set their own limits, and these vary by state. Check each payer, and see the CPT & E/M code guide for the other code families.
