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 Hand

Skin of the right hand is thin dorsally and thick, glabrous, and richly innervated on the palmar surface, so excisions here are planned according to which surface is involved, since palmar excisions risk affecting grip function and sensation while dorsal excisions have more forgiving cosmetic and functional margins. Common indications include warts, cysts, and lesions suspicious for malignancy, and the hand's constant use in daily activity makes wound tension and healing a significant consideration in margin planning. Because the hand contains numerous small joints, tendons, and neurovascular bundles just beneath the skin, even superficial excisions require meticulous technique to avoid inadvertent injury to these structures. Laterality must be specified to differentiate this from the left hand.

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.

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.
