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
Tongue
The tongue is a muscular organ essential to mastication, taste, swallowing, and articulation, and total or near-total resection is performed for advanced squamous cell carcinoma involving the oral tongue or base of tongue that has spread beyond what a partial glossectomy could adequately clear. Because the tongue's intrinsic and extrinsic musculature interdigitates without discrete anatomic planes, resection margins are guided by tumor extent rather than natural boundaries, and removal of the entire organ profoundly affects airway protection, speech, and oral intake, typically necessitating free flap reconstruction and often a protective tracheostomy. Coders should distinguish this complete resection from excision of a portion of the tongue, and should note whether adjacent floor-of-mouth or mandibular tissue was resected concurrently, as that would be reported with separate body part values.
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.
