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
Lower Tooth
A lower tooth refers to any tooth in the mandibular arch, anchored by its root in the alveolar portion of the mandible and covered by an enamel crown, functioning together with the opposing maxillary teeth in mastication. Surgical excision applies when a mandibular tooth cannot be removed by simple extraction, such as an impacted third molar, a tooth with ankylosis, or one requiring sectioning and bone removal due to root morphology or fracture. Because the mandibular arch is in close proximity to the inferior alveolar nerve canal, lower tooth excisions, particularly of posterior molars, carry a distinct risk of nerve injury that shapes surgical planning and is not a comparable concern for upper arch procedures. As with upper teeth, documentation should identify the specific tooth to ensure accurate coding.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Qualifier: Single
This qualifier indicates that only one body part of a paired or multiple set, such as one vessel, valve, or vertebral level, was addressed by the procedure. It is distinguished from Multiple, which applies when more than one but not all such structures were treated, and from All, which covers every one of them.
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.
