What 90833 covers

This add-on captures individual psychotherapy that a prescribing clinician provides during the same visit as an evaluation and management service. The typical scenario is a psychiatrist, psychiatric nurse practitioner, or physician assistant who reviews symptoms, side effects, and medications, then spends dedicated time on supportive, cognitive behavioral, or other therapeutic techniques with the patient. It is reported in offices, outpatient clinics, hospitals, nursing facilities, and telehealth settings. Clinicians who cannot bill E/M services, such as psychologists and clinical social workers, use the standalone psychotherapy codes instead.

This level requires 16 to 37 minutes of psychotherapy. Psychotherapy time must be documented separately from E/M time and excluded from any E/M time used to select its level; the E/M may instead be selected by medical decision making. The note should show the therapeutic approach, the patient's response, and the start and stop time or total psychotherapy minutes. As an add-on, 90833 is reported with a primary E/M service and paid within that service's global period.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

90833 billing questions

How do I choose between 90833, 90836, and 90838?

Select by psychotherapy minutes only, excluding E/M time: 16 to 37 minutes reports 90833, 38 to 52 minutes reports 90836, and 53 minutes or more reports 90838. Under 16 minutes, psychotherapy is not separately reported.

Can E/M time and psychotherapy time be combined to pick the E/M level?

No. Psychotherapy minutes cannot count toward an E/M level selected by time. Select the E/M by medical decision making or qualifying E/M time, and document the two services separately.

Can a psychologist or LCSW bill 90833?

No. The code requires a companion E/M service, which these clinicians cannot report. They bill 90832, 90834, or 90837 for individual psychotherapy.

Which primary codes can 90833 be reported with?

It pairs with E/M services such as office and outpatient visits (99202-99205, 99212-99215), hospital inpatient and observation visits, and nursing facility visits. It is not paired with crisis psychotherapy codes 90839 or 90840.

Can interactive complexity be added?

Yes. When factors such as a caregiver's disruptive communication complicate the psychotherapy, 90785 may be reported with 90833. The E/M service alone does not support adding 90785.

Does 90833 need a modifier like 25 on the E/M?

The E/M does not require modifier 25 solely because it is reported with 90833. Document the distinct E/M work and psychotherapy time.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
