Procedure Overview
Inspection procedures on the upper joints involve a surgeon looking at, and often feeling, a joint such as the shoulder, elbow, wrist, or the small joints of the hand and fingers to determine its condition, without any tissue being cut out, repaired, or replaced. This is done either through a small camera inserted through a tiny incision (arthroscopy) or, less commonly, by opening the joint directly for a visual and manual exam. It is typically ordered when a patient has unexplained joint pain, swelling, instability, or a mechanical symptom like catching or locking, and imaging alone has not given a clear answer.
Because the goal is purely diagnostic exploration, an inspection is often the first step in a same-session procedure - the surgeon looks around, decides what is wrong, and then may move directly into a repair or other corrective step within the same operative episode.
Anatomy & Axis Detail
Temporomandibular Joint, Left
On the left side, the temporomandibular joint has the same condyle-disc-fossa arrangement as its counterpart, but is coded separately because dysfunction is frequently unilateral and surgical planning is side-specific. Inspection of this joint is performed to directly visualize the articular disc, condylar head, and synovial lining, most often through a preauricular arthroscopic approach, when symptoms such as popping, deviation on opening, or myofascial pain are not fully explained by imaging. The joint's proximity to the external auditory canal and the facial nerve's temporal branch makes careful portal placement important during exploration. Inspection here may reveal disc displacement, perforation, or degenerative erosion of the condylar surface, findings that determine whether the case proceeds to débridement, disc repositioning, or another therapeutic step within the same operative session.
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 code from this family is appropriate only when inspection is the sole objective of the encounter, or when it is performed on a body part separate from any other procedure done during the same operative episode. Documentation should describe the joint examined, the approach (percutaneous endoscopic for arthroscopy, or open), and confirm that no biopsy, repair, or other definitive intervention was carried out on that same joint.
The most common assignment error is coding an inspection separately when it was actually the exploratory portion of a more definitive procedure on the same joint - PCS guidelines direct that the inspection is not coded separately in that case, since it is inherent to gaining surgical access. Coders also sometimes miss that diagnostic arthroscopy converted to a therapeutic one changes the correct root operation entirely.
