Code Description

ICD-10 F31.70 is a billable code used to indicate a diagnosis of bipolar disorder, currently in remission, most recent episode unspecified.

Key Diagnostic Point:

Bipolar disorder is a chronic mental health condition characterized by significant mood swings, including emotional highs (mania or hypomania) and lows (depression). The code F31.70 specifically refers to a state where the individual is currently in remission, meaning they are not experiencing active symptoms of mania or depression at the time of assessment. The most recent episode is unspecified, indicating that the clinician has not documented whether the last episode was manic, hypomanic, or depressive. This code is crucial for tracking the long-term management of bipolar disorder, as it reflects the patient's current stability and the effectiveness of treatment strategies, which often include mood stabilizers such as lithium or anticonvulsants. Regular monitoring and assessment are essential, as individuals with bipolar disorder have a heightened risk of suicide, necessitating ongoing evaluation of mood, behavior, and overall mental health.
