Bipolar disorder, current episode mixed, unspecified

This code represents bipolar disorder where the patient is currently experiencing a mixed episode, characterized by a rapid alternation or co-occurrence of manic/hypomanic and depressive symptoms. The specific features of this mixed episode are not further specified in the clinical documentation.

Use this code when documentation clearly indicates a diagnosis of bipolar disorder with a current mixed episode, but lacks further detail regarding the specific manic, hypomanic, or depressive features of that mixed state. This code is appropriate when the clinician has not specified if the mixed episode is predominantly manic, predominantly depressive, or if the severity is mild, moderate, or severe.

• Ensure the documentation explicitly states "mixed episode" and "bipolar disorder."
• If the mixed episode is specified as mild, moderate, severe, or with psychotic features, or if it's predominantly manic or depressive, a more specific code within the F31.6 subcategory should be used.
• This code should be sequenced as the primary diagnosis when it is the reason for the encounter.
