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

Eye, Left

Resection of the left eye describes complete surgical removal of the globe, known clinically as enucleation, undertaken when the eye cannot be salvaged or continues to threaten the patient's health. Common indications include intraocular tumors like uveal melanoma or retinoblastoma, a painful blind eye following severe trauma or infection, or prophylactic removal to prevent sympathetic ophthalmia after a penetrating injury to the fellow eye. The procedure involves severing the extraocular muscles and optic nerve so the entire globe can be lifted free of the orbit, while the surrounding orbital tissue, fat, and eyelids remain undisturbed for subsequent reconstruction with an implant and prosthetic eye. Since no portion of the eye is left behind, this qualifies as resection rather than excision, and the left-sided designation is essential given the bilateral nature of the organ.

Approach: External

External approach applies to procedures performed directly on the skin or mucous membrane, or on an accessible body surface, without any instrumentation passing through a puncture or orifice. It covers things like manual reduction of a fracture or excision of a skin lesion. It differs from Via Natural or Artificial Opening in that no internal passage is entered at all, only the exposed surface.

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.
