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, Right Ear
Skin of the right ear is thin, closely adherent to the underlying cartilage, and has limited subcutaneous padding, which means excisions in this location carry a distinct risk of affecting the cartilage or causing noticeable contour change even when the procedure is confined to skin. Indications commonly include removal of actinic keratoses, basal cell carcinomas, or other skin lesions that are frequent on the sun-exposed helix and rim of the ear, as well as excisional biopsy of a suspicious growth. Because the ear's skin is tightly bound to perichondrium, surgeons must dissect carefully to excise the lesion without devascularizing or exposing the underlying cartilage, and reconstruction options are often considered even for skin-limited defects. Coding should confirm the right-side laterality and that the excision was limited to the skin layer rather than extending into cartilage, which would be classified differently.
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.
