CPT® Code 28045

The CPT® Code 28045 refers to the excision of a tumor located in the soft tissue of the foot or toe, specifically when the tumor is situated subfascially, which means it is located beneath the fascia, a connective tissue layer. This procedure is applicable for tumors that measure less than 1.5 cm in size. Soft tissues encompass a variety of structures, including subcutaneous fat, connective tissue, fascia, muscles, tendons, blood vessels, lymph vessels, nerves, and the tissues surrounding joints. Tumors found in these soft tissues can be either benign or malignant. Typically, benign tumors are treated through excision, while small malignant or indeterminate tumors may also be excised if they have well-defined margins. During the excision procedure, the approach may vary depending on the tumor's location. The skin over the tumor may be incised directly, or a skin flap may be created and elevated to provide better access. Once the overlying tissue is dissected, the soft tissue mass is exposed, allowing for the tumor to be excised along with a margin of healthy tissue to ensure complete removal. In some cases, a frozen section may be performed to verify that all margins are free of tumor cells, which is a critical step in ensuring the thoroughness of the excision. After the tumor is removed, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. For tumors located in the subcutaneous fat or connective tissue, different CPT codes are used based on the size of the tumor, while tumors beneath the fascia are specifically addressed with CPT® Code 28045 for those measuring less than 1.5 cm.
