CPT® Code 13122

Add-On Code

Repair, complex, scalp, arms, and/or legs; each additional 5 cm or less (List separately in addition to code for primary procedure)

Complex repair refers to a surgical procedure that involves the closure of a wound using multiple layers of sutures. This type of repair is necessary when the wound is extensive or complicated, requiring more than just a simple closure. The procedure may involve various techniques such as scar revision, debridement (removal of dead or infected tissue), extensive undermining (lifting the skin to allow for better closure), and the use of stents or retention sutures to support the wound during healing. The complex repair is typically performed under local anesthesia, ensuring that the patient remains comfortable while the physician meticulously cleans the wound site and repairs the subcutaneous tissue, dermis, and epidermis. For the closure, dissolving sutures are often utilized for the deeper layers beneath the skin, promoting healing without the need for suture removal. In cases where multiple wounds of similar complexity are present in the same anatomical area, the total length of these wounds is combined to determine the appropriate coding. For instance, CPT® Code 13120 is designated for repairs measuring between 1.1 cm and 2.5 cm, while CPT® Code 13121 is applicable for repairs ranging from 2.6 cm to 7.5 cm. Additionally, CPT® Code 13122 is used to report each additional 5 cm or less of complex repair performed beyond the initial 7.5 cm, and it is billed separately in conjunction with the primary procedure code.
