CPT® Code 26116

The CPT® Code 26116 refers to the excision of a tumor or vascular malformation located in the soft tissue of the hand or finger, specifically when the procedure is performed subfascially, meaning beneath the fascia layer. The fascia is a connective tissue that surrounds muscles, blood vessels, and nerves, and plays a crucial role in the structural integrity of the hand and finger. The excised mass can be either benign or malignant, with benign tumors often being removed through surgical excision. In cases where malignant or indeterminate tumors are present, excision may still be performed if the tumor margins are well-defined, ensuring that healthy tissue is preserved. During the procedure, the surgeon may need to make an incision in the skin directly over the tumor or create a skin flap to gain access to the underlying tissue. Once the overlying tissue is carefully dissected, the soft tissue mass is exposed, allowing for the excision of the tumor or vascular malformation along with a margin of healthy tissue to ensure complete removal. In some instances, a frozen section may be performed to verify that the margins are free of tumor cells, which is critical for ensuring that the tumor has been completely excised. After the excision, drains may be placed as necessary to prevent fluid accumulation, and the surgical wound is typically closed in layers to promote optimal healing. This code is specifically designated for tumors or vascular malformations that are less than 1.5 cm in size and located beneath the fascia, distinguishing it from other codes that apply to superficial tumors or those of larger size.
