Code Description

ICD-10 F31.32 is a billable code used to indicate a diagnosis of bipolar disorder, current episode depressed, 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 of moderate depression indicates that the individual is experiencing a significant depressive episode, which is characterized by symptoms such as persistent sadness, loss of interest in activities, fatigue, changes in sleep patterns, and difficulty concentrating. The severity of the depressive episode is classified as moderate, meaning that the symptoms are impactful but not as severe as in a major depressive episode. This diagnosis requires careful assessment and monitoring, as individuals with bipolar disorder are at an increased risk for suicide, particularly during depressive episodes. Treatment typically involves mood stabilizers, antipsychotics, and psychotherapy, with a focus on managing symptoms and preventing future episodes. Accurate coding is essential for appropriate treatment planning and reimbursement.
