Code Description

ICD-10 F31.71 is a billable code used to indicate a diagnosis of bipolar disorder, in partial remission, most recent episode hypomanic.

Key Diagnostic Point:

Bipolar disorder is a chronic mental health condition characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). The diagnosis of F31.71 indicates that the individual is experiencing a hypomanic episode, which is a milder form of mania, and is currently in partial remission. This means that while the individual may still exhibit some symptoms of the disorder, they are not as severe as during a full-blown episode. Symptoms of hypomania can include increased energy, reduced need for sleep, and heightened irritability or impulsivity. The term 'partial remission' suggests that the individual has not fully recovered from the episode, and ongoing treatment is necessary to manage symptoms and prevent relapse. Treatment often involves mood stabilizers, psychotherapy, and regular monitoring for suicide risk, as individuals with bipolar disorder are at a higher risk for suicidal ideation and attempts. Accurate coding is crucial for effective treatment planning and insurance reimbursement.
