Bipolar disord, in partial remis, most recent epsd hypomanic

This code describes a patient diagnosed with bipolar I disorder who is currently experiencing a partial remission from a hypomanic episode. Partial remission indicates that some symptoms of the hypomanic episode are still present, but they no longer meet the full diagnostic criteria for a hypomanic episode. The patient has a history of at least one manic episode and at least one hypomanic episode.

Use this code when documentation clearly indicates a diagnosis of bipolar I disorder, with the most recent mood episode identified as hypomanic, and the patient is currently in partial remission. Supporting documentation should detail the presence of residual hypomanic symptoms that do not meet full criteria, following a period of active hypomania.

• Ensure the documentation specifies "partial remission" and "most recent episode hypomanic" for bipolar I disorder.
• Distinguish from full remission (F31.73) where no significant symptoms are present, or unspecified remission (F31.70).
• Confirm the diagnosis is Bipolar I, not Bipolar II, as hypomanic episodes are a feature of both, but F31 codes are specific to Bipolar I.
