Code Description

ICD-10 F31.73 is a billable code used to indicate a diagnosis of bipolar disorder, in partial remission, most recent episode manic.

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 diagnosis of F31.73 indicates that the patient has experienced a manic episode but is currently in partial remission, meaning that while some symptoms may still be present, they are not severe enough to meet the full criteria for a manic episode. This condition can significantly impact a patient's daily functioning and quality of life. Treatment typically involves mood stabilizers, antipsychotic medications, and psychotherapy. Patients with bipolar disorder are at an increased risk for suicide, particularly during depressive episodes or when experiencing mixed features. Regular assessment of mood, suicidal ideation, and overall mental health is crucial for effective management and prevention of relapse.
