ICD-10 Code F30 – Manic episode (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F30 – Manic episode
What it is
F30 identifies a manic episode, a period of abnormally elevated, expansive, or irritable mood with increased energy or activity. It is used when the episode is clinically recognized and documented.
Clinical signs
Typical features include decreased need for sleep, pressured speech, racing thoughts, inflated self-esteem, distractibility, and increased goal-directed activity. Clinical features vary; refer to documentation.
When to use this code
Use F30 when the record clearly documents a manic episode as the current diagnosis. It may apply in bipolar disorder presentations or when mania is described without a more specific subtype. Code only when the clinician identifies mania rather than a different mood state.
Do not use for
Do not use this code for hypomania, depressive episodes, or mood changes due to substances or another medical condition unless documentation supports mania. Check documentation.
Coding tip
Confirm that the provider documents “manic episode” or equivalent language before assigning F30.
