Operation Definition

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

Procedure Overview

Resection of an upper joint refers to the surgical removal of an entire joint structure, such as a joint surface, a disc, or a whole joint component, without replacing it with a prosthetic or graft. This differs from a simple excision because the entire designated body part, not just a portion of it, is taken out. Common reasons for this procedure include severe joint destruction from advanced arthritis, chronic infection that has damaged the joint beyond repair, a tumor involving the joint, or irreparable trauma.

Because the joint is removed entirely rather than reconstructed in the same operation, patients may experience a temporary or permanent change in joint function, and the procedure is sometimes a staged step before a later reconstructive or replacement surgery. In other cases, such as removal of a damaged intervertebral disc component in the upper spine's facet or costovertebral joints, resection relieves pressure on nearby nerves or eliminates a source of chronic pain and instability.

Anatomy & Axis Detail

Temporomandibular Joint, Right

The right temporomandibular joint connects the mandibular condyle to the temporal bone and is unique among synovial joints for its intra-articular fibrocartilaginous disc and its paired, side-by-side function with its left counterpart during chewing and speech. Resection of this joint entails removing the condyle, disc, or joint components entirely, performed for end-stage degenerative or inflammatory arthritis, ankylosis, recurrent dislocation unresponsive to conservative measures, or tumor involving the condylar head. Because the joint lies adjacent to the facial nerve, external auditory canal, and middle cranial fossa, resection demands careful surgical planning to avoid injury to these structures, and reconstruction with a prosthesis or costochondral graft often follows in the same operative episode. Documentation should clarify whether the procedure removed the entire joint or only reshaped it, as the latter would instead be coded as a different root operation.

Approach: Open

Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.

Coding & Documentation

A Resection code applies when documentation confirms the entire joint or the entire designated joint component was excised, with no biological or synthetic material put in its place during the same operative episode. Coders need to read closely for language distinguishing a full resection from a partial excision, since Excision is the correct root operation when only part of the joint structure is cut out. If a replacement device or graft is inserted in the same operative session, the case may require an additional Replacement or Supplement code rather than being reported as a stand-alone Resection. A frequent error is assigning Resection when the surgeon actually performed a synovectomy or debridement limited to soft tissue lining the joint rather than removal of the joint structure itself, which belongs to Excision instead.

Commonly Confused With

ExcisionResection is frequently confused with Excision, and the distinguishing factor is always completeness: Excision removes only a portion of the body part while Resection removes it entirely.
ReplacementIt is also confused with Replacement, which is used when the excised joint structure is taken out and a device or biological substitute is put in during the same procedure; a pure Resection with no replacement is coded alone, while a resection immediately followed by implantation of a new joint surface is typically captured under Replacement.
