Code Description

ICD-10 F31.89 is a billable code used to indicate a diagnosis of other bipolar disorder.

Key Diagnostic Point:

Other bipolar disorder encompasses a range of mood disorders characterized by episodes of mania, hypomania, and depression that do not fit the criteria for the more commonly recognized bipolar I or II disorders. Patients may experience significant mood fluctuations that can lead to impaired functioning in social, occupational, or other important areas. Symptoms can include elevated mood, increased energy, decreased need for sleep, racing thoughts, and impulsive behavior during manic episodes, while depressive episodes may present with feelings of sadness, hopelessness, fatigue, and suicidal ideation. The diagnosis requires careful assessment to differentiate it from other mood disorders and to identify the specific nature of the bipolar symptoms. Treatment often involves mood stabilizers, antipsychotic medications, and psychotherapy, with a strong emphasis on monitoring for suicide risk, as individuals with bipolar disorder are at an increased risk for self-harm during both manic and depressive episodes. Accurate diagnosis and coding are crucial for effective treatment planning and resource allocation.
