ICD-10 Code F31.5 – Bipolar disorder, current episode depressed, severe, with psychotic features (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.5 – Bipolar disorder, current episode depressed, severe, with psychotic features
What it is
This code identifies bipolar disorder when the current episode is depressed, severe, and includes psychotic features such as delusions or hallucinations. Use it when the record clearly documents both the depressive episode and psychosis.
Clinical signs
Typical findings include a major depressive episode with marked functional impairment, along with mood-congruent or mood-incongruent psychotic symptoms. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bipolar disorder with a current severe depressive episode and psychotic features. It also fits when the note states bipolar depression with psychosis, as long as severity and current episode are clear. Check documentation if the record does not specify the episode or psychosis.
Do not use for
Do not use this code for bipolar disorder in remission, hypomania, mania, or depression without psychotic features. Do not guess severe or psychotic status if the documentation is incomplete.
Coding tip
Confirm the current episode, severity, and psychotic features in the provider note before assigning F31.5.
