ICD-10 Code F31.1 – Bipolar disorder, current episode manic without psychotic features (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.1 – Bipolar disorder, current episode manic without psychotic features
What it is
This code identifies bipolar disorder with a current manic episode, but no psychotic features are documented. Use it when the record supports mania without hallucinations, delusions, or similar psychotic symptoms.
Clinical signs
Typical findings include elevated or irritable mood, increased energy, decreased need for sleep, pressured speech, and racing thoughts. Clinical features vary; refer to documentation.
When to use this code
Use F31.1 when the clinician documents bipolar disorder and clearly states the current episode is manic without psychotic features. It may also fit notes describing a manic state with no psychosis mentioned. If the documentation is unclear, check documentation.
Do not use for
Do not use this code if psychotic features are present, if the episode is depressive or mixed, or if the record does not support bipolar disorder. Check documentation.
Coding tip
Confirm that “without psychotic features” is explicitly documented before assigning F31.1.
