Behavioral Health Coding: Therapy Time, E/M Add-Ons, and the Two-Service Visit

Two services in one visit, coded as one

Psychiatric providers routinely deliver two distinct services in a single visit, the therapy and the medical management, and code for one. The structure to capture both already exists.

The Two-Service Visit: E/M Plus a Psychotherapy Add-On

If you are a prescriber (psychiatrist, PMHNP, PA) and the visit includes both medication management and genuine psychotherapy, those are two separately codable services: an office E/M for the medical portion (99212-99215, selected by MDM) plus a psychotherapy add-on for the therapy portion:

A 99214 plus 90833 adds roughly 50% to the wRVU value of the visit (90833 carries 0.95 wRVUs against the 99214's 1.92), for therapy many prescribers already do and document as an afterthought. The add-ons cannot be coded alone, and non-prescribing clinicians use the standalone codes below instead.

Standalone Psychotherapy: The Time Brackets

For psychotherapy without a medical E/M component (psychologists, LCSWs, LPCs, and prescribers in therapy-only visits), the codes are strictly time-based:

The nominal session names are not the rule; the time ranges are (90837 carries 2.58 wRVUs). Actual face-to-face therapy of 53 minutes or more is a 90837, and reflexively downcoding to 90834 out of caution is undercoding. A scheduled "hour" that delivered 50 minutes of therapy is a 90834, and rounding up is upcoding. Document exact start and stop times, because the brackets are precisely what an auditor checks.

Evaluations, Crisis, and the Codes Around the Edges

Initial psychiatric diagnostic evaluations use one of two codes, split by whether medical services were included. 90791 is the evaluation without medical services (history, mental status examination, formulation), used by non-prescribing clinicians such as psychologists and licensed therapists. 90792 is the same evaluation with medical services (medical assessment and decision making such as ordering labs, a physical examination, or prescribing), reported only by clinicians whose licensed scope and payer enrollment support that work, and it pays more (about 2.80 wRVUs). "Prescriber" is shorthand; the criterion is the documented medical work. Many payers cover one evaluation per patient per provider per year, so verify before building intake-heavy templates. Crisis psychotherapy (90839 for the first 30 to 74 minutes, plus 90840 for each additional 30) covers urgent assessment of a patient in acute distress, pays better than routine therapy, and requires documentation of the crisis state and disposition.

For Primary Care: The Integration Codes

Family physicians and internists deliver a large share of behavioral health care, and two structures pay for it. First, the E/M-plus-add-on logic applies to any prescriber: a PCP managing an SSRI who also provides 16+ documented minutes of structured therapy can code the add-on. Second, the Collaborative Care Model codes (99492-99494) and the general behavioral health integration code (99484) pay for monthly psychiatric care management delivered through your practice with a psychiatric consultant. If your practice runs a CoCM program and these codes never appear on your reports, raise it with your administrator. The primary care guide (The 25 Codes That Pay Primary Care) lists the same codes in the context of a full primary care day.

Telehealth: Where Behavioral Health Lives Now

All core psychotherapy and psychiatric E/M codes are telehealth-eligible, and behavioral health retains the most durable telehealth coverage in Medicare. The claim is dressed the same way as any telehealth visit, modifier and place of service included, with one behavioral health wrinkle: some payers want modifier FQ rather than 93 for audio-only. The general modifier and place-of-service rules are in the telehealth guide. Audio-only psychotherapy remains covered under Medicare rules that outlasted the general telehealth flexibilities, which many coding offices have not caught up with. These rules are the most frequently revised in this guide and payers diverge from Medicare; this section reflects rules as reviewed in August 2026, and current payer policy controls.

A Psychiatric Visit, Worked Through

A psychiatrist sees an established patient for medication management of depression and provides 30 minutes of psychotherapy in the same visit. That is two coded components: an office E/M for the medication management, selected by MDM, plus the psychotherapy add-on for the therapy time (+90833 at 30 minutes), documented as its own block distinct from the E/M work. Coding only one component undercaptures a visit that contained both, the most commonly undercoded combination in behavioral health.
