CPT® Code 11103

Add-On Code

Tangential biopsy of skin (eg, shave, scoop, saucerize, curette); each separate/additional lesion (List separately in addition to code for primary procedure)

A tangential biopsy of the skin, as described by CPT® Code 11103, involves the removal of small, raised skin lesions through various techniques such as shave, scoop, saucerization, or curettage. This procedure is typically employed for lesions that may include dermal nevi, non-melanocytic malignant tumors like squamous cell and basal cell carcinomas, as well as inflammatory or bullous skin disorders. The technique utilizes a flexible blade or an obliquely oriented curette or scalpel to excise the lesion. The tangential shave biopsy specifically targets the superficial layer of the skin, reaching down to the depth of the reticular dermis, while the tangential saucerization biopsy extends deeper, removing skin, reticular deep dermis, and potentially subcutaneous fat. Prior to the procedure, local anesthesia is administered as necessary to minimize discomfort. The shave biopsy technique involves the scalpel blade entering the skin tangentially, sliding beneath the lesion, and moving parallel to the skin until it reaches the opposite side. In contrast, the saucerization technique requires the blade to be bent to enhance the depth of the excised tissue. Additionally, a sharp curette may be employed to scrape and smooth the dermis, ensuring the complete removal of any residual lesion. To manage any bleeding that may occur during the procedure, methods such as electrocautery, aluminum chloride, or Monsel’s solution can be utilized. It is important to note that CPT® Code 11102 is used to report the removal of a single lesion via tangential skin biopsy, while CPT® Code 11103 is designated for each additional lesion removed during the same procedure.
