2025 ICD-10-CM code B07.9

Viral wart, unspecified. This code is used when the type of viral wart is not documented.

If the type of wart is known, a more specific code under category B07 should be used.If the wart is anogenital (venereal), use code A63.0. For warts of the bladder, cervix, or larynx, use codes D41.4, D26.0, and D14.1, respectively.

Medical necessity for treatment is determined by factors such as pain, interference with function, cosmetic concerns, and the number and location of the warts.

Diagnosis is typically made through physical examination. A biopsy can be done to confirm the diagnosis. Treatment is not always necessary, as warts can often resolve on their own. If treatment is required, it can involve cryotherapy, excision, electrosurgery, or curettage.

In simple words: This code represents a diagnosis of a wart caused by a virus, but the specific type of wart isn't identified in the medical record.

A viral wart is a noncancerous growth that occurs in the outermost layer of the skin (the epidermis).It is caused by the human papillomavirus (HPV), which enters the skin through tiny cracks or cuts.Viral warts can appear as flat or slightly raised, rough or scaly, and painless lesions. A black dot may be present in the center of the wart. This code is used when the provider does not specify the type of viral wart.

Example 1: A patient presents with a small, rough growth on their finger. The provider diagnoses it as a viral wart, but does not specify the type, therefore, B07.9 is used., A patient has multiple warts on their foot, but the physician doesn't specify if it is a Plantar wart, therefore, B07.9 is used., A child has a smooth, flat wart on their face. The provider identifies it as a viral wart but doesn't document the specific type, so B07.9 is applied.

Documentation should include the location and appearance of the wart(s). If a biopsy is performed, the results should also be documented.
