ICD-10 Code F33 – Major depressive disorder, recurrent (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F33 – Major depressive disorder, recurrent
What it is
F33 identifies recurrent major depressive disorder, meaning the patient has had more than one major depressive episode. Use it when documentation shows repeated episodes of depression rather than a single episode.
Clinical signs
Clinical features vary; refer to documentation. Common findings include persistent low mood, loss of interest, sleep or appetite changes, fatigue, poor concentration, and feelings of worthlessness during separate depressive episodes.
When to use this code
Use F33 when the record clearly states recurrent major depressive disorder or describes a history of multiple major depressive episodes. Apply the most specific subcode when the chart identifies current severity, remission status, or episode details. Check documentation if the recurrence is not explicit.
Do not use for
Do not use F33 for a single major depressive episode, adjustment disorder, or depressive symptoms without a documented major depressive disorder diagnosis. Check documentation if the provider has not confirmed recurrence.
Coding tip
Confirm that the note supports both major depressive disorder and recurrence before assigning F33, and select a more specific subcode when available.
