Code Description

ICD-10 B07.9 is a billable code used to indicate a diagnosis of viral wart, unspecified.

Key Diagnostic Point:

Viral warts, also known as verrucae, are benign epithelial tumors caused by human papillomavirus (HPV) infection. They can appear on various parts of the body, including the hands, feet, and face, and are characterized by rough, raised lesions. The transmission of HPV occurs through direct contact with infected skin or surfaces, making them common in communal areas such as swimming pools and locker rooms. While most viral warts are harmless and may resolve spontaneously, they can be bothersome and may require treatment for cosmetic reasons or if they cause discomfort. Treatment options include cryotherapy, topical treatments, and surgical removal. Vaccination against HPV can help prevent certain types of warts and associated cancers, although it does not eliminate the risk of all wart types. Complications from viral warts are rare but can include secondary bacterial infections or scarring from aggressive treatment methods. Understanding the nature of viral warts and their management is essential for effective patient care and accurate coding.
