Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision in the ear, nose, and sinus family covers surgically cutting away a portion of a structure, such as a polyp, tumor, or diseased segment of tissue, while leaving the rest of the body part intact. It is distinct from removing an entire structure and is used when only part of the tissue is abnormal or accessible.
Common reasons for this type of surgery include removing nasal polyps that block airflow, taking a biopsy sample from a suspicious growth in the nose or ear canal, or shaving down overgrown turbinate tissue that is causing chronic congestion. These procedures may be done through an endoscope passed through the nostril, directly through the ear canal, or through a small external incision, depending on where the tissue is located.
Recovery is usually brief, and many of these excisions double as both treatment and a way to obtain tissue for a pathologist to examine, which helps confirm whether a growth is benign or requires further care.
Anatomy & Axis Detail
Accessory Sinus
Accessory sinus is the body part used for the ethmoid and sphenoid sinuses collectively, the air-filled cavities situated deep within the skull near the orbits and optic nerves. Excision of accessory sinus tissue involves cutting out diseased mucosa, polyps, or a discrete lesion from these spaces, commonly performed endoscopically as part of managing chronic sinusitis, fungal sinus disease, or a localized tumor. The ethmoid sinus's thin bony partitions bordering the orbit and anterior skull base, and the sphenoid sinus's proximity to the carotid artery and optic nerve, make this one of the more anatomically demanding excisional sites in the sinonasal region. Documentation should identify whether the ethmoid, sphenoid, or both were involved, since this affects specificity even though ICD-10-PCS groups them under a single accessory sinus body part.
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.
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
To assign a code here, the documentation must show that only a portion of the body part was cut out, with the remainder left in place. Operative notes should clearly identify the anatomic site (for example, inferior turbinate versus nasal polyp versus external ear) because the body part character changes the code substantially, and biopsy intent versus therapeutic removal should be distinguished with the diagnostic qualifier when appropriate.
A common mistake is coding a polypectomy or turbinate reduction as Extirpation, since both may sound like "removal" in casual language, when the correct root operation depends on whether abnormal tissue was cut out (Excision) versus solid matter like a stone or foreign body was taken out (Extirpation). Another frequent slip is failing to code a biopsy separately when a diagnostic excision precedes a more extensive therapeutic procedure in the same operative session.
