    ICD-10-CM Code For Other Viral Infections Characterized By Skin And Mucous Membrane Lesions: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B08 includes viral infections that cause skin and mucous membrane lesions that are not classified elsewhere, such as certain viral exanthems and mucosal ulcerations. These ICD-10-CM diagnosis codes are used to document clinical encounters where a viral etiology produces dermatologic or mucosal lesions, capturing disease presentation, severity, and anatomic involvement. Accurate coding within the ICD-10-CM B08 group supports proper claim adjudication and complete clinical documentation.

    Typical Clinical Scenarios

    • An adult presents to urgent care with a 3-day history of painful grouped vesicular lesions strictly following a unilateral thoracic dermatome, accompanied by fever and acute neuropathic chest wall pain; the clinician documents acute viral reactivation of varicella-zoster involving skin and mucous membranes and starts antiviral therapy. Typical codes: B08.0, B08.01.
    • A pediatric patient with known immunodeficiency has recurrent, persistent mucocutaneous lesions of the oral cavity and perioral skin that have failed standard outpatient therapy, prompting referral for specialist management and consideration of immune status-related viral disease. Typical codes: B08.4, B08.5.
    • An elderly nursing home resident develops widespread vesiculopustular rash with secondary bacterial superinfection and systemic symptoms after a recent exposure; the hospitalization records both the underlying viral mucocutaneous infection and the complicating infection to guide inpatient treatment. Typical codes: B08.69, B08.79.
