What B08 covers · when clinicians use it
ICD-10 code B08 identifies Other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified in the U.S. ICD-10-CM clinical and billing record set. It sits within the Certain Infectious and Parasitic Diseases chapter (A00–B99), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply B08 when an encounter's findings match the Other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify B08 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for B08 and is a coding reference, not clinical, diagnostic, or billing advice.
B08 refers to Other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified, a viral condition primarily affecting the skin and mucous membranes. These infections may range from mild and self-limiting to severe or life-threatening, particularly in immunocompromised individuals. Accurate use of this ICD10 code supports clinical documentation, treatment planning, and outbreak surveillance.
Symptoms
- Skin rash – Red, itchy, or blistering eruptions common in most of these infections
- Fever – Often accompanies viral skin infections like measles or chickenpox
- Mouth sores – Frequently seen in herpes and measles
- Fatigue – Systemic viral infections may lead to prolonged tiredness
- Swollen lymph nodes – Especially in herpes and rubella cases
- Respiratory symptoms – Cough or runny nose may occur in measles or rubella
- Scarring – May occur post-infection, especially in smallpox or zoster
Diagnosis
Diagnosis of Other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified is primarily clinical, based on skin lesion appearance, distribution, and associated symptoms. Lab tests like PCR, viral cultures, and serology may confirm the viral pathogen, especially in atypical or severe cases. Early and accurate diagnosis helps with treatment and isolation, particularly in contagious infections like measles or monkeypox.
ICD10 Code Usage
ICD10 code B08 is used for precise classification in medical records, insurance billing, and public health databases. It helps identify and track outbreaks, manage treatment protocols, and assess disease burden. Accurate coding also supports vaccination strategies and epidemiological studies on viral skin infections.
