ICD-10 Code F31.73 – Bipolar disorder, in partial remission, most recent episode manic (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.73 – Bipolar disorder, in partial remission, most recent episode manic
What it is
This code identifies bipolar disorder with a most recent manic episode that is now only partly controlled or improved. You use it when the condition is still present, but the patient is not currently fully manic.
Clinical signs
Clinical features vary; refer to documentation. You may see a history of manic symptoms such as elevated mood, decreased need for sleep, increased activity, or pressured speech, with current improvement but ongoing residual symptoms.
When to use this code
Use this code when the provider documents bipolar disorder in partial remission and specifies the most recent episode was manic. It fits follow-up visits where symptoms have lessened but the disorder remains active. Check documentation if remission status or episode type is unclear.
Do not use for
Do not use this code for bipolar disorder in full remission, or when the most recent episode is depressive, mixed, or unspecified. If the record does not confirm partial remission, check documentation.
Coding tip
Code only when both “partial remission” and “most recent episode manic” are documented together.
