ICD-10 Code F31.60 – Bipolar disorder, current episode mixed, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F31.60 – Bipolar disorder, current episode mixed, unspecified
What it is
F31.60 identifies bipolar disorder with a mixed current episode, meaning manic and depressive features occur together. The “unspecified” label means the record does not document the exact severity or other qualifying details.
Clinical signs
Clinical features vary; refer to documentation. Mixed episodes may include elevated or irritable mood, increased energy, racing thoughts, and simultaneous depression, such as low mood, hopelessness, or loss of interest.
When to use this code
Use this code when the provider documents bipolar disorder with a current mixed episode and does not specify the episode details further. It fits notes that clearly describe both manic and depressive symptoms at the same time. If the record identifies a more specific bipolar subtype or episode severity, code that instead.
Do not use for
Do not use this code for bipolar disorder in remission, a purely manic episode, or a purely depressive episode. Check documentation if the note only says “bipolar disorder” without confirming a mixed current episode.
Coding tip
Code F31.60 only when the mixed episode is explicitly documented and no more specific bipolar code is supported.
