Viral infections characterized by skin and mucous membrane lesions (B00-B09)

ICD-10 codes B00-B09 cover viral infections that cause lesions on the skin and mucous membranes. These include well-known conditions like herpes simplex (B00), chickenpox or varicella (B01), herpes zoster or shingles (B02), smallpox (B03), and other viral infections marked by distinctive rashes or sores.

This range is used to specify various viral diseases characterized by skin and mucosal lesions with precision, aiding medical coders in choosing the correct code based on infection type and complications. For example, B00 includes herpes simplex infections such as eczema herpeticum and herpesviral keratitis, often known as oral herpes or cold sores. Codes like B01 classify varicella (chickenpox) and its neurological complications. B02 represents herpes zoster, including postherpetic neuralgia and ocular diseases linked to shingles. Other important entries are B05 for measles, B06 for rubella or German measles, and B07 for viral warts. Rare viral infections such as monkeypox (B04) and parapoxvirus infections (B08) are also included. These codes facilitate detailed documentation of viral infections that manifest prominently on the skin or mucous membranes, supporting accurate diagnosis and treatment.
