Code Description

ICD-10 F31.11 is a billable code used to indicate a diagnosis of bipolar disorder, current episode manic without psychotic features, mild.

Key Diagnostic Point:

F31.11 refers to a specific diagnosis of bipolar disorder characterized by a current manic episode that is mild in severity and does not include psychotic features. Patients with this diagnosis may exhibit elevated mood, increased energy, and heightened activity levels, but these symptoms are not severe enough to cause significant impairment in social or occupational functioning. The absence of psychotic features means that the individual does not experience hallucinations or delusions, which can complicate the clinical picture. This diagnosis is part of a broader category of mood disorders, which also includes depressive episodes and mixed episodes. Treatment typically involves mood stabilizers, such as lithium or valproate, and may also include psychotherapy. It is crucial to assess the risk of suicide in these patients, as mood disorders can significantly elevate this risk, particularly during manic episodes. Regular monitoring and comprehensive treatment plans are essential for managing symptoms and preventing relapse.
