ICD-10-CM Code For Bipolar Disorder: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group F31 includes diagnoses of bipolar disorder, covering bipolar I and bipolar II presentations and specifying current or most recent episode type and severity such as manic, hypomanic, depressed, or in remission. These ICD-10-CM diagnosis codes are used to document the clinical course, episode status, and severity of mood episodes, capturing important distinctions like psychotic features or remission. Accurate coding within the ICD-10-CM F31 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM F31: Bipolar Disorder Overview

The ICD-10-CM F31 group represents bipolar disorder diagnoses, mood disorders characterized by episodes of mania, hypomania, and depression affecting mood regulation and functioning. These conditions target the psychiatric/behavioral health domain and can involve cognitive and psychosocial impairment. Accurate coding matters for complete clinical documentation and for appropriate reimbursement tied to documented severity and episode type.

When to Use

Use a code from this group when a patient has a diagnosed bipolar disorder and the clinician documents the current or most recent episode type and severity. Choose the specific code that matches documented features such as manic versus depressive episode, psychotic features, or remission status.

Typical Clinical Scenarios

A young adult presents to the emergency department with 5 days of markedly elevated mood, decreased need for sleep, pressured speech, grandiose ideas, and impulsive reckless spending leading to serious financial consequences; collateral history reveals prior episodes of major depression. A diagnosis from this group is assigned because symptoms meet criteria for a manic episode with a history of bipolar illness and require mood stabilizer and possible inpatient stabilization. Typical codes: F31.2, F31.1
A middle-aged patient in outpatient psychiatry has persistent cycles of depressive episodes interspersed with hypomanic periods over several years, causing occupational impairment but no history of hospitalization or psychosis; current visit documents a depressive episode without psychotic features. A code from this group is used to capture bipolar disorder, most recent episode depressed, to guide ongoing mood disorder management and longitudinal tracking. Typical codes: F31.4, F31.10
An older adult nursing home resident with known bipolar disorder presents with acute confusion and worsening depressive symptoms while on multiple medications; the clinician documents bipolar disorder with current episode severe with psychotic features complicating dementia management and medication adjustments. A diagnosis from this group is assigned to reflect the severe, psychotic mood episode as a comorbid condition affecting treatment planning and monitoring. Typical codes: F31.5, F31.7}
