ICD-10 Code F31.76 – Bipolar disorder, in full remission, most recent episode depressed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.76 – Bipolar disorder, in full remission, most recent episode depressed
What it is
This code identifies bipolar disorder when the patient is currently in full remission and the last episode was depressed. Use it when the diagnosis is established and the chart shows no active mood episode.
Clinical signs
Clinical features vary; refer to documentation. In full remission, you should not see current manic, hypomanic, or depressive symptoms meeting episode criteria, although the bipolar diagnosis remains active in the record.
When to use this code
Use this code when the clinician documents bipolar disorder with full remission and specifies the most recent episode was depressed. It is appropriate for follow-up visits, maintenance care, or history review when no active episode is present. Check documentation if the remission status is unclear.
Do not use for
Do not use it for bipolar disorder with current depression, mania, or hypomania. Also avoid it if the record only says bipolar disorder without remission status or most recent episode details.
Coding tip
Verify both “full remission” and “most recent episode depressed” in the provider note before assigning F31.76.
