Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
This family covers excision procedures performed on general anatomical regions rather than on a single named organ - areas such as the neck, chest wall, back, abdominal wall, buttock, perineum, and the retroperitoneal or mediastinal spaces. A surgeon cuts out a portion of tissue from one of these regions, leaving the rest of the body part in place and not replacing what was removed. Common reasons include removing a suspicious lump for biopsy, taking out a mass or growth that does not clearly belong to a single organ, or debriding a limited area of diseased tissue.
Because these regions sit between or around named organs, excisions here are often diagnostic - a piece of tissue goes to pathology to determine whether something is infection, scar, or cancer. They may also be therapeutic, such as removing a soft tissue tumor from the chest wall or a mass in the perineum.
Patients are told about this procedure when imaging or a physical exam finds an abnormal area that cannot be safely watched and needs to be sampled or removed.
Anatomy & Axis Detail
Face
Excision of the face targets the soft tissue and skin overlying the midface and lateral facial planes, excluding structures with their own designations like the eyes, nose, or jaws. Surgeons remove portions here for skin cancers, cysts, traumatic wounds requiring debridement, or congenital lesions such as nevi, always balancing tissue removal against the cosmetic and functional demands of an area rich in mimetic muscles, sensory branches of the facial and trigeminal nerves, and the parotid duct. Because facial skin is thin and highly visible, even limited excisions are often planned with margins that account for reconstructive closure. This code applies broadly to facial soft tissue rather than to a named subcomponent, so documentation should be reviewed to confirm no more specific facial structure was actually resected.
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
A code from this family is assigned when the operative note documents cutting out a portion of tissue from a general body region - not a whole organ, layer, or body part with its own dedicated body system table. The surgeon's language ('excised,' 'resected a portion of') and the specific region named in the note both drive code selection, since the qualifying body part values here are broad regional terms rather than organ names.
The most frequent assignment error is reaching for these general-region tables when a more specific body system actually applies - for example, coding a breast lesion excision here instead of under the breast-specific body system, or a skin lesion under the integumentary system instead. Coders should confirm the tissue excised truly falls into a general region (mediastinum, retroperitoneum, abdominal wall, and similar) before defaulting to this family, and should distinguish partial removal (excision) from removal of an entire body part (resection), which uses a different root operation.
