Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures remove a portion of skin or breast tissue without replacing it, and this family spans everything from a shave biopsy of a suspicious mole to a lumpectomy removing a breast tumor with a margin of surrounding tissue. The common thread is that a defined piece of tissue, not the entire organ or structure, is cut away and typically sent to a pathology lab for examination.
Patients most often encounter this family when a mole, cyst, or lump needs to be evaluated or treated, or when a breast biopsy is needed to characterize a finding seen on imaging. Because only part of the body part is taken, the surrounding skin or breast tissue remains intact, which distinguishes these procedures from more extensive surgery that removes an entire structure.
Anatomy & Axis Detail
Skin, Abdomen
Abdominal skin is frequently excised for benign lesions such as lipomas and cysts, but it also carries surgical relevance in bariatric and reconstructive contexts where redundant skin is removed after significant weight loss. The abdominal wall's skin overlies a layered muscular and fascial structure, so care is taken to keep the excision plane superficial when the intent is limited to skin removal rather than a more extensive procedure involving fascia or hernia repair. Striae, prior surgical scars, and umbilical anatomy can complicate margin planning, particularly when lesions sit near the umbilicus or old incision lines. Coders should confirm the excised tissue was limited to skin and did not include panniculus or fascia, which would change the root operation or body part.
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
Documentation should describe the amount of tissue removed, any margins taken, and whether the intent was diagnostic (an excisional biopsy) or therapeutic. Coders must pay close attention to whether the note describes removal of only part of the breast or skin versus the entire body part, since removing an entire breast is coded to Resection rather than Excision even though both involve cutting tissue away. A common mistake is coding a partial mastectomy or wide local excision as Resection out of habit, or conversely under-coding a case that actually removed the whole breast as Excision.
