CPT Code Overview
CPT code 10121 describes the incision and removal of a foreign body from subcutaneous tissues when the procedure is considered complicated. This service falls under surgical procedures on the skin, subcutaneous, and accessory structures.

The complexity may involve factors such as difficult anatomical location, risk of infection, or the need for specialized surgical technique.
Clinical & Coding Specifications
Clinical Context
A patient presents to the office or emergency department after sustaining an injury that results in a complicated subcutaneous foreign body, such as glass or metal, embedded beneath the skin. The wound may be associated with lacerations or open injuries, and removal requires a surgical incision due to complexity (e.g., deep location, irregular shape, or risk of infection). The procedure is performed by a physician specializing in surgery, orthopaedic surgery, or emergency medicine. The clinical workflow includes assessment, local anesthesia, surgical incision, removal of the foreign body, wound exploration, and closure as appropriate.
