ICD Coding
  • ICD-9-CM Codes: 078.1
  • ICD-10-AM Codes: A63.00, B07
Brief description

Warts are benign growths on the skin or mucosa caused by infection with human papilloma virus (HPV).  They can affect any area of the skin as well as the cervix uteri. The SOP covers warts of the skin and cervix and anogenital warts.

Confirming the diagnosis

This diagnosis is made on clinical grounds.  A biopsy may be needed in some cases of anogenital warts, to confirm the diagnosis and exclude malignancy.  Testing for human papilloma virus is unhelpful.

The appropriate medical specialist depends on the location of the warts but may be a dermatologist, urologist or gynaecologist.

Clinical onset

Clinical onset will be based on self-report of when the lesions first appeared.  There may be different clinical onsets for different body sites.

Clinical worsening

The course of warts is unpredictable.  They may spontaneously resolve, persist, or progress.  A variety of topical treatments are available, but these wont cure the underlying infection.  Establishing that worsening beyond the normal course has occurred will be difficult and will generally require specialist opnion.
