Code Description

ICD-10 F31.1 is a billable code used to indicate a diagnosis of bipolar disorder, current episode manic without psychotic features.

Key Diagnostic Point:

F31.1 refers to a specific diagnosis of bipolar disorder characterized by a current manic episode that does not include psychotic features. Patients with this condition experience an elevated or irritable mood, increased energy, and heightened activity levels. Symptoms may include grandiosity, decreased need for sleep, talkativeness, distractibility, and involvement in high-risk activities. Unlike manic episodes with psychotic features, patients do not exhibit delusions or hallucinations. This diagnosis is crucial for treatment planning, as it guides the use of mood stabilizers and other therapeutic interventions. The absence of psychotic features allows for a different approach in management, focusing on mood stabilization and monitoring for potential suicide risk, which is heightened during manic episodes. Accurate coding is essential for appropriate treatment reimbursement and to ensure that patients receive the necessary care.
