ICD-10 Code F30.9 – Manic episode, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F30.9 – Manic episode, unspecified
What it is
F30.9 identifies a manic episode when the record does not specify the type or severity. Use it for an episode of abnormally elevated, expansive, or irritable mood with increased energy when details are limited.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include decreased need for sleep, pressured speech, racing thoughts, distractibility, and increased goal-directed activity or agitation.
When to use this code
Use this code when the clinician documents a manic episode but does not specify whether it is mild, moderate, severe, or with psychotic features. It is also appropriate when the note confirms mania without enough detail for a more specific code. Check documentation for bipolar disorder or other underlying diagnoses.
Do not use for
Do not use this code for hypomania, mixed episodes, or mood changes that are better explained by substances or a medical condition. If the chart gives a more specific manic episode code, use that instead.
Coding tip
If the provider’s note is vague, code only what is explicitly documented and query for missing mania details when needed.
