CPT® Code 11471

The procedure described by CPT® Code 11471 involves the excision of skin and subcutaneous tissue specifically for the treatment of hidradenitis located in the perianal, perineal, or umbilical regions. Hidradenitis is a chronic dermatological condition that manifests as swollen, painful, and inflamed lesions affecting the cutaneous apocrine glands, which are responsible for sweat production. This condition can lead to significant discomfort and may also involve the surrounding subcutaneous tissue and fascia. In cases of suppurative hidradenitis, the presence of draining sinus tracts, also known as fistulas, is common in the affected areas. Surgical intervention is primarily indicated for suppurative hidradenitis, where the excision involves removing the skin and subcutaneous tissue that overlies the apocrine glands, along with any fistulous tracts that may be present. The extent of the excision can vary, with severe cases necessitating the removal of a significant amount of tissue. Following the excision, the wound is typically closed using a complex repair technique, which may involve more than just a layered closure. This complex repair can include extensive undermining, the use of stents, or retention sutures to ensure proper healing. In some instances, additional procedures such as skin grafts or flaps may be required to adequately close the surgical wound.
