ICD-10 Code F31.10 – Bipolar disorder, current episode manic without psychotic features, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.10 – Bipolar disorder, current episode manic without psychotic features, unspecified
What it is
This code identifies bipolar disorder with a current manic episode, but without psychotic features. Use it when the record shows mania and does not specify the bipolar subtype.
Clinical signs
Typical findings include elevated or irritable mood, increased energy, reduced need for sleep, pressured speech, racing thoughts, and impulsive behavior. Clinical features vary; refer to documentation.
When to use this code
Use F31.10 when the provider documents bipolar disorder with mania and no hallucinations, delusions, or other psychotic features. It also fits when the episode is manic but the chart does not identify the specific bipolar type. Confirm the current episode and documentation wording before assigning the code.
Do not use for
Do not use this code if psychotic features are documented, or if the episode is depressive, mixed, or unspecified. Check documentation when the bipolar subtype is stated more specifically.
Coding tip
Code the highest level of specificity available, and verify that “without psychotic features” is explicitly supported in the record.
