Operation Definition
Cutting out or off, without replacement, all of a body part
Procedure Overview
Resection procedures on the skin and breast involve cutting out an entire body part rather than a sample or lesion. In this family, that most often means a mastectomy for breast cancer, or occasionally full-thickness removal of skin over a defined region, such as the entire nipple-areolar complex. The defining feature is completeness: the surgeon takes the whole named structure, not a margin around a mass.
These operations are done when disease, most commonly malignancy, has progressed to the point where partial removal would leave unacceptable risk of recurrence, or when the anatomy itself is being eliminated for prevention, such as a prophylactic mastectomy in a patient with a strong genetic predisposition. Reconstruction, if performed, is coded separately as its own procedure.
Recovery and follow-up depend heavily on what was resected and why, but the shared thread is that the tissue removed does not grow back and no portion of the original structure remains in that location.
Anatomy & Axis Detail
Toe Nail
Resection of a toe nail is the complete removal of the nail plate together with the nail bed and matrix, most often performed for severe or recurrent ingrown toenails, chronic fungal or bacterial infection resistant to other treatment, traumatic deformity, or a lesion suspicious for malignancy within the nail unit. Because toenails bear repetitive mechanical stress from footwear and ambulation, chronic conditions here are common indications for definitive matrix removal rather than repeated partial excisions. As with fingernails, permanent removal of the germinal matrix, rather than just the visible plate, is what distinguishes this root operation from excision, since destroying or removing the matrix prevents nail regrowth. Documentation should specify which toe and whether the procedure was total or limited to a portion of the nail unit.
Approach: External
External approach applies to procedures performed directly on the skin or mucous membrane, or on an accessible body surface, without any instrumentation passing through a puncture or orifice. It covers things like manual reduction of a fracture or excision of a skin lesion. It differs from Via Natural or Artificial Opening in that no internal passage is entered at all, only the exposed surface.
Coding & Documentation
The operative note must state that the entirety of the body part, such as the whole breast, was removed, not just a nodule or wedge. Pathology confirming a full specimen and the surgeon's language describing complete removal are what supports Resection over Excision.
The most common assignment error is choosing Resection when the documentation actually describes a partial procedure, such as a lumpectomy or partial mastectomy, which is coded to Excision instead. Coders also sometimes miss that skin resections are distinct from breast resections at the body part level, even though both fall under the same root operation, so the correct body part character still has to reflect exactly which structure, left or right breast, or a specific skin region, was taken.
