CPT Code Overview

CPT 90840 describes each additional 30 minutes of psychotherapy for crisis, billed in addition to CPT 90839. This service is a form of crisis psychotherapy provided within the broader scope of psychiatry and behavioral health. It applies when a patient requires extended, focused therapeutic intervention to address an acute psychiatric crisis beyond the initial 60 minutes covered by the primary crisis psychotherapy code.

Typical sites of service include facility and non-facility settings such as hospitals, skilled nursing facilities, physician offices, the patient’s home, or via telehealth.

Clinical Context

A 38-year-old patient presents to the emergency department after an acute panic attack with severe anxiety and safety concerns. The patient is evaluated by a behavioral health clinician in a facility setting. The clinician conducts an initial crisis psychotherapy session lasting 75 minutes, with the first 60 minutes billed under 90839 and the remaining 15 minutes billed as an additional 30-minute increment using 90840. The workflow includes triage by emergency staff, urgent psychiatric assessment, crisis-focused psychotherapy to de-escalate symptoms and address immediate safety, documentation of time-based psychotherapy intervals, coordination with inpatient psychiatry or community resources as appropriate, and discharge planning with follow-up recommendations.

Related CPT Codes

• 90839 is the primary code for the initial 60 minutes of crisis psychotherapy. 90840 is billed in addition to 90839 for each additional 30-minute increment.

• These codes are commonly used together in a single extended crisis psychotherapy encounter where total treatment time exceeds 60 minutes. 90839 is not an alternative to 90840; rather, 90840 supplements 90839 when additional time is provided.
