ICD-10 Code F31.11 – Bipolar disorder, current episode manic without psychotic features, mild (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.11 – Bipolar disorder, current episode manic without psychotic features, mild
What it is
This code identifies bipolar disorder with a current manic episode that is mild and does not include psychotic features. Use it when the record clearly documents bipolar disorder and the episode severity.
Clinical signs
Clinical features may include elevated or irritable mood, increased energy, reduced need for sleep, rapid speech, and distractibility. Symptoms are present but mild enough that overall impairment is limited; clinical features vary, so refer to documentation.
When to use this code
Use F31.11 when the provider documents bipolar disorder with a current manic episode, no psychotic features, and mild severity. It is appropriate for encounters focused on assessment, monitoring, or follow-up of that specific episode. Check documentation if severity or psychosis is not stated.
Do not use for
Do not use this code if the record describes psychotic features, a different mood episode, or a severity level other than mild. Do not assign it when the diagnosis is uncertain or not documented.
Coding tip
Confirm all three elements in the note: bipolar disorder, current manic episode, and mild severity without psychosis.
