CPT® Code 11451

The procedure described by CPT® Code 11451 involves the excision of skin and subcutaneous tissue specifically in the axillary region, commonly known as the armpit, to treat a condition known as hidradenitis. 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, or fistulas, is common in the axillary area, indicating a more severe form of the disease that necessitates surgical intervention. The surgical procedure entails the excision of the affected skin and subcutaneous tissue, including the removal of any exposed fistulous tracts. In instances of severe suppurative hidradenitis, extensive excision of all involved tissues is required to adequately address the condition. The closure of the surgical wound following this excision is a critical aspect of the procedure. While CPT® Code 11450 allows for simpler closure techniques, such as single-layer or intermediate repairs, CPT® Code 11451 specifically denotes a complex repair. This complex repair involves more intricate techniques that may include extensive undermining, the use of stents, or retention sutures to ensure proper healing. Additionally, in some cases, a separately reportable skin graft or flap may be necessary to achieve optimal closure of the surgical site.
