ICD-10-CM Code For Unspecified Viral Infection Characterized By Skin And Mucous Membrane Lesions: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B09 includes unspecified viral infections characterized by skin and mucous membrane lesions, capturing mucocutaneous eruptions and vesicular or ulcerative lesions when a specific viral agent is not documented. These ICD-10-CM diagnosis codes are used to document clinical encounters where viral mucocutaneous disease is present but not otherwise specified, capturing disease severity, lesion distribution, and associated systemic involvement as documented. Accurate coding within the ICD-10-CM B09 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM B09: Unspecified Viral Infection Characterized By Skin And Mucous Membrane Lesions Overview
This group captures unspecified viral infections that present primarily with lesions of the skin and mucous membranes, such as mucocutaneous vesicular or ulcerative eruptions when a specific viral etiology is not identified. It targets dermatologic and mucosal surfaces affected by viral processes and includes cases where clinical features suggest a viral cause but laboratory confirmation is lacking. Accurate coding matters because it supports complete clinical documentation and appropriate reimbursement for care related to evaluation and treatment of these presentations.
