Procedure Overview
Inspection describes a procedure performed solely to look at or manually examine a lower joint, without repairing, removing, or otherwise treating what is found. It is most often carried out through arthroscopy of the hip, knee, ankle, or foot joints, using a camera and instruments introduced through small incisions, though open exploration is also possible. Surgeons use this approach to evaluate unexplained pain, swelling, or mechanical symptoms like locking or catching when imaging has not provided a clear answer.
Because the goal is purely diagnostic, a patient undergoing this procedure may leave the operating room with no further intervention if the joint appears normal, or the surgeon may proceed directly to a therapeutic procedure such as debridement or repair if a problem is identified during the same session.
Anatomy & Axis Detail
Tarsometatarsal Joint, Right
The right tarsometatarsal joints, collectively known as the Lisfranc joint complex, connect the cuneiforms and cuboid to the bases of the five metatarsals and form a keystone arch critical to midfoot stability during push-off. Inspection here is most commonly indicated after a Lisfranc injury, where even subtle diastasis between the first and second metatarsal bases signals ligamentous disruption requiring further imaging or fixation. Surgeons may directly visualize the joint through a dorsal incision or arthroscopically to evaluate cartilage wear, malalignment, or occult fracture not evident on plain radiographs, particularly in athletes with persistent midfoot pain after a twisting injury. Because these joints have limited independent motion but bear substantial load, even minor instability can predispose to progressive arthritis, making careful intraoperative assessment of joint congruity an important step before deciding on repair versus fusion.
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
Documentation must show that the joint was examined visually or manually and describe the findings, even if the findings were unremarkable. When an inspection leads directly to a therapeutic procedure on the same structure during the same operative episode, only the definitive procedure is coded - the inspection is not coded separately, per coding guideline B3.1b. This is the single most common assignment error in this family: coders sometimes add a separate Inspection code alongside a Repair or Excision performed on the same joint in the same session. Inspection is appropriately coded on its own only when no further treatment is done, or when a different, unrelated body part is inspected without additional procedure.
Commonly Confused With
Inspection is most often confused with diagnostic arthroscopy that turns therapeutic mid-procedure - the rule of thumb is that the more definitive root operation always supersedes a preceding inspection of the same body part. It differs from Release or Repair in that no correction of the joint occurs; the surgeon only observes and reports.
