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
Knee Joint, Left
The left knee joint comprises the femorotibial and patellofemoral articulations, stabilized by the anterior and posterior cruciate ligaments along with the medial and collateral structures, and cushioned by the medial and lateral menisci that are vulnerable to tearing under twisting loads. Diagnostic arthroscopic inspection lets a surgeon directly examine articular cartilage, meniscal contour, and ligament tension, often resolving discrepancies between clinical suspicion and imaging results. This inspection frequently serves as the first step in a staged procedure, guiding the decision to proceed with repair, debridement, or reconstruction based on what is visualized. Laterality documentation is required to differentiate this from the right knee joint in coding.
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
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.
