ICD-10 Code F32.9 – Major depressive disorder, single episode, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F32.9 – Major depressive disorder, single episode, unspecified
What it is
F32.9 identifies a single episode of major depressive disorder when the record does not specify the severity or subtype. Use it for a depressive episode that meets major depressive disorder criteria, but lacks further detail.
Clinical signs
Typical findings include depressed mood, loss of interest, sleep or appetite change, fatigue, poor concentration, and feelings of worthlessness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents major depressive disorder, single episode, but does not state whether it is mild, moderate, severe, or in remission. It also fits when the note confirms a major depressive episode without additional qualifying detail. Check documentation if the record suggests recurrent depression or another mood disorder.
Do not use for
Do not use F32.9 for recurrent major depressive disorder, bipolar depression, or adjustment disorder with depressed mood. Avoid it when the chart specifies a more exact depressive episode code.
Coding tip
Code the most specific depressive episode documented, and query for severity or recurrence when the note only says “depression.”
