ICD-10 Code F31.12 – Bipolar disorder, current episode manic without psychotic features, moderate (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.12 – Bipolar disorder, current episode manic without psychotic features, moderate
What it is
This code identifies bipolar disorder with a current manic episode of moderate severity and no psychotic features. Use it when the record specifies mania without delusions, hallucinations, or other psychotic symptoms.
Clinical signs
Typical findings include elevated or irritable mood, increased energy, decreased need for sleep, pressured speech, racing thoughts, and impulsive behavior. Clinical features vary; refer to documentation.
When to use this code
Use F31.12 when the provider documents bipolar disorder and clearly describes the current episode as manic, moderate, and without psychotic features. This is appropriate for encounters focused on assessment, monitoring, or ongoing management of that episode.
Confirm that the record supports bipolar disorder rather than a single manic episode or another mood disorder. If severity, psychotic features, or current episode are unclear, check documentation before assigning the code.
Do not use for
Do not use this code for mania with psychotic features, hypomania, or bipolar disorder in remission. Also avoid it if the chart does not identify the episode as moderate.
Coding tip
Match the code to the provider’s exact wording for episode type, severity, and psychotic status.
