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

Larynx

The larynx houses the vocal folds and cartilaginous framework responsible for voice production, airway protection during swallowing, and respiration. Resection of the larynx refers to total laryngectomy, the complete removal of the laryngeal structure, an operation reserved for advanced laryngeal or hypopharyngeal cancer that cannot be controlled with organ-preserving therapy, or for severe irreparable trauma. The procedure requires separating the airway from the digestive tract, since the trachea is brought forward to form a permanent stoma while the pharynx is reconstructed to maintain a swallowing passage. This anatomic disconnection distinguishes total laryngectomy from partial laryngeal procedures, which remove only a portion of the structure and preserve some combination of voice, airway, or swallowing function, making complete Resection coding specific to total organ removal.

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

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.
