Code Description

ICD-10 F31.63 is a billable code used to indicate a diagnosis of bipolar disorder, current episode mixed, severe, without psychotic features.

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, severe, without psychotic features indicates that the patient is experiencing a combination of manic and depressive symptoms simultaneously, which can lead to significant impairment in daily functioning. Symptoms may include irritability, racing thoughts, decreased need for sleep, and feelings of hopelessness or worthlessness. The absence of psychotic features means that the patient does not exhibit delusions or hallucinations, which can complicate the clinical picture. This severe episode can increase the risk of self-harm or suicidal ideation, necessitating careful monitoring and intervention. Treatment typically involves mood stabilizers, antipsychotic medications, and psychotherapy to manage symptoms and reduce the risk of future episodes.
