ICD-10 Code F32.4 – Major depressive disorder, single episode, in partial remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F32.4 – Major depressive disorder, single episode, in partial remission
What it is
Use this code for a single episode of major depressive disorder when symptoms have improved but some depressive features remain. The episode is not fully resolved, so the patient is in partial remission.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see reduced mood symptoms with lingering signs such as low interest, fatigue, sleep disturbance, or impaired concentration.
When to use this code
Assign F32.4 when the record clearly states a single major depressive episode is in partial remission. Use it when the clinician documents improvement without full recovery, and the episode is not described as recurrent or in full remission.
Do not use for
Do not use this code for recurrent major depressive disorder, full remission, or depressive symptoms that do not meet major depressive disorder criteria. Check documentation if the note is unclear.
Coding tip
Look for the exact wording “single episode” and “partial remission” in the assessment before assigning F32.4.
