Code Description

ICD-10 F31.0 is a billable code used to indicate a diagnosis of bipolar disorder, current episode hypomanic.

Key Diagnostic Point:

Bipolar disorder, current episode hypomanic (F31.0) is characterized by a distinct period of abnormally elevated, expansive, or irritable mood lasting at least four consecutive days. During this episode, individuals may exhibit increased energy, decreased need for sleep, racing thoughts, distractibility, and heightened goal-directed activities. The hypomanic episode is less severe than a manic episode and does not cause significant impairment in social or occupational functioning. However, it can lead to risky behaviors and poor decision-making. Diagnosis requires a thorough clinical assessment, including a detailed history of mood changes and any previous episodes of mania or depression. The condition is part of a spectrum of mood disorders, which also includes major depressive episodes. Treatment often involves mood stabilizers, antipsychotics, and psychotherapy, with careful monitoring for potential suicide risk, as individuals with bipolar disorder have a higher incidence of suicidal ideation and attempts.
