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

Nipple, Left

Left nipple excision addresses the same range of indications as the right, including Paget disease evaluation, persistent nipple discharge or erosion of unclear cause, or planned removal as part of reconstructive or gender-affirming surgery, and is coded separately to capture laterality. Because the nipple sits at the convergence of the lactiferous ducts, any excisional biopsy taken here can yield diagnostic information about ductal pathology deeper within the breast even though only the nipple structure itself is removed. Surgeons typically use a small elliptical or wedge excision to preserve as much surrounding areolar skin as possible when the goal is diagnostic rather than reconstructive. Sensory nerve disruption is a recognized and usually discussed risk of this procedure. Clear documentation of laterality and the anatomic limitation to nipple tissue is essential for accurate coding.

Approach: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

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.

Commonly Confused With

ResectionResection is the procedure family most easily confused with Excision, and the deciding factor is simply how much of the body part was removed: any portion is Excision, the entire body part is Resection.
ExtirpationExtirpation is also sometimes conflated with Excision, particularly during debridement, since excisional debridement of dead tissue is coded as Excision while nonexcisional scraping or washing away of necrotic material is Extirpation.
