Operation Definition

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

Procedure Overview

Resection procedures in the eye involve cutting out an entire body part without replacing it, most notably enucleation of the globe for conditions such as intraocular tumors, severe trauma, or a blind and painful eye, and evisceration or excision of other complete ocular structures like the lacrimal gland. These are definitive, irreversible procedures reserved for situations where a structure is diseased beyond salvage or poses an ongoing risk, such as malignancy or infection, that outweighs any benefit of preserving it.

Because Resection removes an entire body part rather than a portion of it, these procedures carry significant functional and cosmetic consequences, and they are typically followed by reconstructive or prosthetic planning as a separate consideration. The decision to resect is made only after other treatment options have been exhausted or are not viable given the severity of the underlying condition.

Anatomy & Axis Detail

Extraocular Muscle, Right

The right extraocular muscles - the four recti and two obliques - anchor to the sclera and orbital walls to coordinate conjugate eye movement, and complete resection of one of these muscles is a decisive step reserved for severe, refractory strabismus, restrictive myopathy, or muscle involvement by orbital tumor where the muscle itself is beyond salvage rather than simply repositioned. Because the muscle's insertion site and length directly determine ocular alignment, surgeons document precisely which of the six muscles was excised, since recti and obliques have distinct actions and removing one permanently eliminates its contribution to gaze. Coders should distinguish resection, which takes the entire muscle at its point of origin, from more limited procedures like myectomy portions or recession, which merely detaches and reattaches the muscle without excising it.

Approach: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

Coding & Documentation

Coders assign Resection when the documentation confirms complete removal of an entire named body part, such as the whole eyeball in enucleation or the entire lacrimal gland, distinguishing it from partial excision procedures that would be coded as Excision instead. The operative note must clearly state that the entire structure was removed, not merely a lesion or portion of it, and coders need to identify the precise qualifying body part being resected.

A common error is applying Resection to biopsy or partial tumor excision cases where only a lesion or segment of tissue was removed, which actually falls under Excision; another is confusing enucleation, evisceration, and exenteration, three distinct eye removal procedures with different anatomic scope that require careful reading of the operative report to code correctly.

Commonly Confused With

ExcisionResection is frequently confused with Excision, since both involve cutting tissue out, but Excision applies to removal of only a portion of a body part while Resection requires removal of the entire structure.
RepositionIt is also distinguished from Reposition, since strabismus surgery colloquially called muscle "resection" does not meet the PCS definition of Resection because the muscle remains attached at a new site rather than being entirely removed.
