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
Cornea, Right
The right cornea is the transparent, avascular dome at the front of the eye that refracts incoming light and forms a protective barrier over the anterior chamber. Full-thickness resection of the cornea, essentially removal of the entire corneal structure, is an uncommon and severe intervention typically reserved for extensive corneal destruction from perforating trauma, aggressive infection, or tumor that cannot be managed with a lesser procedure like keratoplasty. Because the cornea is avascular and depends on the tear film and limbal stem cells for its integrity, its complete loss leaves the eye without its primary refractive and protective surface, usually necessitating immediate reconstruction with a corneal graft or other tectonic support to preserve the globe. Precise laterality documentation matters given that corneal pathology and prior interventions frequently differ between the two eyes.
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.
