ICD-10 Code B07 – Viral warts (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B07 – Viral warts
What it is
B07 identifies viral warts, which are benign skin growths caused by human papillomavirus infection. Use it when the record documents common warts, plantar warts, or other viral wart lesions without a more specific subtype.
Clinical signs
Typical findings include rough, raised papules or plaques that may be skin-colored, hyperkeratotic, or verrucous. Clinical features vary; refer to documentation.
When to use this code
Use B07 when the provider documents viral warts and does not specify a more detailed ICD-10 option. It also fits cases where the wart location or subtype is unclear in the note. Check documentation if the record suggests another skin lesion or a nonviral diagnosis.
Do not use for
Do not use B07 for nonviral skin growths, calluses, or other lesions that are not documented as warts. If the chart names a different HPV-related condition or another specific diagnosis, code that condition instead.
Coding tip
Code from the provider’s exact wording and avoid assuming the wart type or site when the note is nonspecific.
