Code Description

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

Key Diagnostic Point:

Bipolar disorder is a mood disorder characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). The current episode manic without psychotic features indicates that the patient is experiencing a manic episode, which is marked by an elevated mood, increased energy, and often impulsive behavior, but without the presence of delusions or hallucinations. Symptoms may include inflated self-esteem, decreased need for sleep, talkativeness, racing thoughts, distractibility, and excessive involvement in activities that have a high potential for painful consequences. This unspecified designation is used when the clinician does not specify the severity or duration of the manic episode, or when the details are not documented. Accurate diagnosis and treatment are crucial, as individuals with bipolar disorder are at a higher risk for suicide and may require mood stabilizers or other medications to manage their symptoms effectively.
