Operation Definition

Cutting out or off, without replacement, all of a body part

Procedure Overview

Resection procedures remove an entire ear, nose, or sinus structure without replacing it, most often to treat cancer, extensive chronic infection, or irreversible structural damage. A total mastoidectomy, which clears out diseased mastoid air cells down to the bone in cases of severe chronic otitis media or cholesteatoma, is a common example, as is total or subtotal removal of a nasal or sinus structure for tumor control. Total auriculectomy, removing the entire external ear, may be performed for skin cancer that has invaded the ear's cartilage framework.

Because resection removes the whole body part rather than just a portion, it's a more definitive and often more disfiguring intervention than partial excision, and it's usually reserved for situations where conservative treatment or partial removal wouldn't adequately control disease. Reconstruction, if performed, happens as a separate step - sometimes in the same operative session, sometimes staged for later.

Anatomy & Axis Detail

Ethmoid Sinus, Left

The left ethmoid sinus consists of multiple small air cells wedged between the nasal cavity and the orbit, bounded above by the cribriform plate and laterally by the paper-thin lamina papyracea. Resection removes the entire ethmoid labyrinth on that side, most often for sinonasal malignancy or aggressive inverted papilloma extending through the ethmoid cells, frequently as part of a larger skull base or orbital procedure. The proximity of these thin bony walls to the orbit and anterior cranial fossa makes precise, image-guided dissection important to avoid injury to the eye or a cerebrospinal fluid leak. Because the ethmoid sinus is frequently addressed only partially in endoscopic sinus surgery, documentation should clearly support complete removal to code it as resection.

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

Resection applies only when documentation confirms the entire named body part was removed, not a portion of it; removing part of a turbinate or part of the septum is Excision, not Resection, so coders need to read the operative note carefully for words like 'total,' 'complete,' or a clear statement that the whole structure was taken. Pathology reports describing the specimen can help confirm the extent of removal when the operative note is ambiguous.

The most frequent error is applying Resection to procedures that actually removed only a portion of a body part, inflating the code to a higher-acuity procedure than what was performed. Coders should also be alert to mastoidectomy terminology, since 'cortical' or 'simple' mastoidectomy is usually a partial procedure (Excision) while 'radical' or 'total' mastoidectomy meets the threshold for Resection.

Commonly Confused With

ExcisionResection is most often confused with Excision, and the entire-versus-partial distinction is what separates them - this is the single most important documentation detail to verify.
ReplacementIt's also distinct from Replacement, since Resection leaves no substitute in place, and from Destruction, which eradicates tissue in place (such as with cautery or laser) rather than cutting it out.
