ICD-10 Code B07.9 – Viral wart, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B07.9 – Viral wart, unspecified
What it is
B07.9 identifies a viral wart when the record does not specify a subtype or site. Use it for a wart caused by human papillomavirus when documentation is nonspecific.
Clinical signs
Warts are typically small, rough, and raised skin growths. Clinical features vary; refer to documentation for location, appearance, and whether the lesion is consistent with a common viral wart.
When to use this code
Use B07.9 when the provider documents “viral wart” or “wart, unspecified” without further detail. It also fits when the note confirms a wart but does not identify the type, such as common, plantar, or flat wart. Check documentation if the lesion site or subtype is recorded.
Do not use for
Do not use this code for nonviral skin lesions, calluses, or neoplasms. If the record specifies a different wart type or a more specific site, code that instead.
Coding tip
Query the provider when the note says only “wart” and the type is unclear, because a more specific ICD-10 code may be available.
