Operation Definition

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

Procedure Overview

This family covers the complete surgical removal of a mouth or throat structure, performed without replacing it with any substitute material. Tonsillectomy, adenoidectomy, total glossectomy for tongue cancer, and total laryngectomy are the best-known examples, though resection also applies to complete removal of smaller structures such as the uvula or the epiglottis when the entire structure is taken. The defining feature is that the whole body part, not just a piece of it, is removed.

These procedures are most often performed to treat cancer, to relieve chronic infection or obstruction as with recurrent tonsillitis or sleep apnea, or to address a severely diseased structure that cannot be salvaged. Because losing an entire structure such as the tongue or larynx has major consequences for eating, breathing, and speaking, resection is frequently followed by reconstructive procedures performed either in the same operative session or as a staged second surgery.

Anatomy & Axis Detail

Soft Palate

The soft palate is the mobile, muscular posterior extension of the palate that elevates during swallowing and speech to seal off the nasopharynx, containing muscles such as the tensor and levator veli palatini. Complete resection is reserved for malignant tumors of the soft palate or tonsillar pillar that have infiltrated this structure, and because the soft palate is essential for velopharyngeal closure, its removal produces significant functional deficits in speech resonance and swallowing that drive the choice of reconstructive flap. Surgeons often resect the soft palate together with adjacent tonsil or base of tongue tissue in oropharyngeal cancer, so documentation must clarify that this code applies specifically to the palatal muscle and mucosa rather than to contiguous pharyngeal wall tissue removed in the same operative session.

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 need documentation confirming that an entire named body part was removed, not merely a lesion, margin, or portion of it; operative notes should describe complete excision of the structure by name, such as "total glossectomy" or "complete tonsillectomy." The most common error is applying resection when only a partial removal occurred, which should instead be coded as excision, or when the structure removed is better classified as an entire versus a specific defined body part in the ICD-10-PCS body part table. Coders should also verify whether reconstruction was performed in the same session, since that requires an additional replacement or supplement code alongside the resection.

Commonly Confused With

ExcisionExcision is the procedure most often confused with resection, and the distinction rests entirely on completeness: excision removes only a portion of a body part, while resection removes all of it.
ReplacementReplacement frequently follows resection in the same encounter when a substitute is placed for the removed structure, but the two remain separately coded steps.
DestructionDestruction is a different approach altogether, eliminating abnormal tissue in place through energy or chemicals rather than surgically cutting the structure out.
