Code Description

ICD-10 F31.60 is a billable code used to indicate a diagnosis of bipolar disorder, current episode mixed, unspecified.

Key Diagnostic Point:

Bipolar disorder is a mood disorder characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). The current episode mixed, unspecified indicates that the patient is experiencing symptoms of both mania and depression simultaneously, but the specific details of the episode are not clearly defined. This can manifest as irritability, racing thoughts, and impulsive behavior alongside feelings of sadness, hopelessness, and fatigue. The mixed episode can be particularly challenging to manage due to the conflicting nature of the symptoms, which can lead to increased risk of self-harm or suicidal ideation. Treatment typically involves mood stabilizers, antipsychotic medications, and psychotherapy. Accurate diagnosis and coding are crucial for effective treatment planning and management, as well as for ensuring appropriate reimbursement for services rendered.
