Code Description

ICD-10 F31.62 is a billable code used to indicate a diagnosis of bipolar disorder, current episode mixed, moderate.

Key Diagnostic Point:

Bipolar disorder is a mental health condition characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). The current episode mixed, moderate designation indicates that the patient is experiencing symptoms of both mania and depression simultaneously, which can complicate diagnosis and treatment. Symptoms may include irritability, racing thoughts, decreased need for sleep, and feelings of hopelessness or worthlessness. The moderate classification suggests that the severity of symptoms is significant enough to impact daily functioning but does not reach the level of severe impairment. Treatment often involves mood stabilizers, antipsychotics, and psychotherapy. Given the dual nature of symptoms, careful monitoring for suicide risk is essential, as individuals with mixed episodes may have an increased risk of self-harm due to the combination of depressive and manic symptoms.
