CPT® Code 11107

Add-On Code

Incisional biopsy of skin (eg, wedge) (including simple closure, when performed); each separate/additional lesion (List separately in addition to code for primary procedure)

An incisional biopsy of the skin, as described by CPT® Code 11107, is a surgical procedure that involves the removal of a small wedge-shaped section of tissue from a skin lesion. This procedure is primarily performed to obtain a sample for pathological examination, allowing healthcare professionals to identify the cellular composition and type of cells present within the lesion. Incisional biopsies are particularly indicated for larger lesions where a complete excision may not be feasible or when it is necessary to determine the most appropriate treatment options while ensuring a satisfactory cosmetic outcome. The procedure begins with the careful marking of the biopsy area, followed by the administration of a local anesthetic to minimize discomfort. A scalpel is then utilized to make an incision along the marked lines, extending down to the subcutaneous tissue to create a small island of skin and tissue. This island is subsequently grasped with forceps and excised, ensuring that the specimen is collected for further pathological analysis. After the specimen is removed, the wound is assessed for any bleeding, and the edges of the skin are approximated to facilitate closure. The procedure may involve the use of absorbable sutures in the subcutaneous layer to reduce tension and promote healing, followed by the closure of the skin with either sutures or staples. It is important to note that CPT® Code 11107 is specifically used to report the incisional biopsy of each separate or additional lesion, distinguishing it from CPT® Code 11106, which pertains to a single skin lesion biopsy.
