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, Right

The right nipple, including the nipple papilla and immediately adjacent areolar tissue, is excised for conditions such as Paget disease of the breast, chronic non-healing nipple lesions, symptomatic accessory tissue, or as part of gender-affirming or reconstructive procedures rather than for typical fibroadenoma or cyst removal, which involve deeper breast parenchyma instead. Because the nipple contains the terminal openings of the lactiferous ducts, excision here can affect future lactation and sensation, considerations that are usually discussed with the patient beforehand. The nipple-areolar complex has a rich sensory nerve supply, so even a limited excision can result in altered sensitivity. This body part is coded separately from breast tissue excision, so operative notes must be reviewed carefully to determine whether the nipple itself, rather than underlying glandular tissue, was the structure removed.

Approach: Via Natural or Artificial Opening

Via Natural or Artificial Opening means the instrument reaches the target site by passing through an existing body orifice, such as the mouth or urethra, or a surgically created opening like a stoma, without additional incision or scope guidance. It is distinguished from the Endoscopic variant by the absence of a visualizing scope, and from External by actually traversing into the body through that opening.

Qualifier: Diagnostic

Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.

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.
