Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures in the mouth and throat remove a defined portion of tissue - a lesion, ulcer, or mass - from structures such as the lips, tongue, gums, palate, tonsils, adenoids, uvula, or pharynx, while leaving the rest of the structure in place. Surgeons perform them to obtain tissue for biopsy, remove precancerous or cancerous growths with a margin of healthy tissue, treat chronic infection or airway obstruction, or reshape structures like an elongated uvula or excess soft palate tissue contributing to snoring or sleep apnea. Because only part of the body part is taken and nothing replaces it, the structure keeps functioning afterward, sometimes with a changed contour, sensation, or speech quality at the site. Most of these procedures are outpatient. Recovery time and side effects such as swallowing discomfort, taste changes, or temporary speech alteration scale with how much tissue was removed and its location; larger oral or tongue excisions occasionally require reconstruction with a local flap or graft.
Anatomy & Axis Detail
Vocal Cord, Left
The left vocal cord, paired with its right-sided counterpart within the larynx, is composed of mucosa overlying the vocalis muscle and vibrates during phonation while also closing to protect the lower airway during swallowing. Excision on this side is performed for the same range of lesions seen on the right, including polyps, nodules, papilloma, leukoplakia, or early malignancy, and is likewise typically carried out endoscopically with attention to preserving the pliable mucosal cover needed for normal vibration. Because voice outcome depends heavily on how much of the superficial lamina propria is disturbed, the extent of excision is often kept as conservative as the pathology allows. As with the right cord, laterality must be documented precisely, since left- and right-sided vocal cord procedures are coded separately even when the underlying pathology and technique are identical.
Approach: Via Natural or Artificial Opening Endoscopic
Via Natural or Artificial Opening Endoscopic describes instrumentation introduced through a natural orifice or a surgically created opening while using an endoscope for visualization, as in a routine colonoscopy performed through the anus. It differs from the plain Via Natural or Artificial Opening value by the added scope, and from Percutaneous Endoscopic by using an existing passage rather than a new skin puncture.
Coding & Documentation
A coder assigns an excision code when the operative note documents cutting a portion of tissue from an otherwise intact body part - a biopsy, a partial glossectomy, a wedge resection of a lip lesion, or a partial tonsillectomy. The note must specify the exact anatomic site and make clear that only part of the structure was removed, since a complete tonsillectomy or full removal of a body part meets the criteria for Resection instead. That distinction is the most common assignment error in this family - coders sometimes default to Excision for any tonsil or adenoid procedure without checking whether the note says "entire" or "total." Another frequent mistake is coding removal of debris, mucus, or a foreign object as Excision when it actually describes Extirpation, and overlooking laterality for paired structures like the gums or buccal mucosa.
