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

Eustachian Tube, Right

The right eustachian tube connects the middle ear to the nasopharynx, equalizing pressure and draining secretions, and runs partly through bone and partly through cartilage as it descends toward the throat. Resection of the entire tube is rare and generally undertaken when tumor invades the tube or when chronic, severe dysfunction with associated disease requires its elimination rather than the dilation or patency procedures used for more routine eustachian tube disorders. Because the tube's course passes near the internal carotid artery and skull base, complete removal is a more extensive undertaking than typical middle ear surgery and is often part of a larger resection for regional malignancy. Operative reports should be reviewed to confirm the tube was excised in its entirety, as opposed to a balloon dilation or partial procedure that would be coded differently.

Approach: Percutaneous Endoscopic

Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.

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.
