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
Breast, Right
The right breast consists of glandular, fibrous, and fatty tissue supported by Cooper's ligaments and is excised to remove palpable masses, biopsy-proven fibroadenomas, or areas of atypical or malignant tissue identified on imaging, most often in the context of a lumpectomy for early-stage cancer. Excision here removes a discrete portion of breast tissue while preserving the remaining gland and skin envelope, distinguishing it from resection, which would take an entire lobe, or mastectomy-level procedures that remove the whole breast. Margin status is critical and often drives re-excision if pathology shows tumor at the cut edge. Surgeons may place clips to guide future radiation planning. Coding depends on confirming laterality and that the procedure removed a portion of breast parenchyma rather than the nipple, skin, or entire gland.
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.
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.
