CPT Codes for Psychotherapy at a glance
This page covers CPT codes for psychotherapy in mental health billing: what the codes cover, how payers apply them, and what to document. Psychotherapists and psychiatrists both use these CPT codes for psychotherapy, so the sections below call out differences where they matter. Payer rules for CPT codes for psychotherapy vary, so confirm current requirements with the payer before you bill.
The CPT codes for psychotherapy are billed by time with the patient, or with the patient and a family member. Choose among the CPT codes for psychotherapy by the face-to-face minutes you document: 90832 for 16 to 37 minutes, 90834 for 38 to 52 minutes, and 90837 for 53 minutes or more. Record start and stop times in every note that carries one of the CPT codes for psychotherapy, because payers check the time against the code.

Code list entry
“Psychotherapy with patient”
What the service is
“CPT Codes 90832-90838 represent psychotherapy. Psychotherapy without medical evaluation and management services are reported as 90832, 90834 and 90837.”
“Psychotherapy services (CPT codes 90832-90838) are time-based codes. Start and stop times or total times must be documented for CPT codes 90832, 90834, and 90837.”
“Psychotherapy times are for face-to-face services with the patient. The patient must be present for all or some of the service.”
“Individual psychotherapy codes should be used only when the focus of the treatment encounter involves psychotherapy. Psychotherapy codes should not be used as generic psychiatric service codes when another code, such as an E/M or pharmacological management code, would be more appropriate.”

Psychotherapists and psychiatrists

When psychotherapy happens in the same visit as medication management, you report an E/M plus an add-on code instead. See the add-on codes page.
Frequently asked questions
What are the time ranges for 90832, 90834 and 90837?
90832 is 16–37 minutes, 90834 is 38–52 minutes, and 90837 is 53 minutes or more. A Medicare contractor article on CMS.gov (A57520) quotes these ranges. There is no code for 75 or 90 minutes.
If a session does not last 15 minutes, is it billable?
Not under the time ranges for these codes. The shortest psychotherapy code, 90832, covers 16 to 37 minutes, as quoted in a Medicare contractor article on CMS.gov (A57520). Ask the payer whether any other code applies to a very short contact.
Are the start and end times of the session required in the note?
Yes, document them. CMS contractor article A57520 says start and stop times, or the total time, must be documented for 90832, 90834 and 90837. Other payers can ask for the same in a prior authorization or an audit, and policies differ, so check each payer's policy. We recommend recording the start time and the end time for every session, since that is the clearest proof of which time range applies.
Does the patient have to be in the session?
Contractor article A57520 says psychotherapy times are for face-to-face services with the patient, and the patient must be present for all or some of the service.
Can I bill a session longer than 90 minutes?
Medicare contractor article A57480 says a session over 90 minutes is paid only if the record documents the face-to-face time and the medical necessity for the extended time. Confirm the rule with each payer.
