ICD-10 Code B97.7 – Papillomavirus as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B97.7 – Papillomavirus as the cause of diseases classified elsewhere
What it is
This code identifies papillomavirus as the infectious cause of another condition, rather than the condition itself. Use it when documentation links HPV or another papillomavirus to a disease classified elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Findings may include warts, dysplastic changes, or other lesions associated with a documented papillomavirus infection.
When to use this code
Use B97.7 when the provider states papillomavirus is the cause of a separate diagnosis and that other condition is coded first. It is commonly used with site-specific or manifestation codes when the record clearly identifies HPV as the cause. If the chart does not connect the virus to another condition, check documentation.
Do not use for
Do not use this code for a standalone wart or lesion without documented papillomavirus causation. Do not use it as the principal diagnosis when the record supports a more specific condition code.
Coding tip
Verify the causal link in the note and sequence the underlying condition first, with B97.7 as an additional code when appropriate.
