Operation Definition
Visually and/or manually exploring a body part
Procedure Overview
Inspection procedures allow a physician to visually and manually explore a general anatomical region without necessarily performing any other definitive treatment during that same look. This includes techniques like exploratory surgery of the abdominal wall, mediastinoscopy to examine the mediastinum, or manual exploration of the pelvic cavity or retroperitoneum after trauma or in the workup of an unexplained finding.
The purpose is diagnostic or exploratory: confirming the extent of an injury, checking for bleeding or infection, evaluating an area seen as abnormal on imaging, or making sure no additional problems are present before or after another procedure. Nothing is removed, repaired, or altered during a pure inspection - the value comes from the direct visual or manual assessment itself.
This type of procedure is often performed when imaging alone cannot answer a clinical question, such as when internal bleeding is suspected, or when a surgeon needs to directly confirm findings before deciding on further treatment.
Anatomy & Axis Detail
Retroperitoneum
The retroperitoneum lies behind the parietal peritoneum and houses the kidneys, adrenal glands, pancreas, aorta, and inferior vena cava, along with surrounding fat and lymphatic tissue. Because this space is not directly visualized during routine abdominal exploration, inspection of the retroperitoneum specifically denotes a deliberate surgical or endoscopic examination of this region, typically to evaluate for hematoma after trauma, retroperitoneal fibrosis, abscess, or tumor extension that cannot be assessed on imaging alone. Access usually requires mobilizing the peritoneum and adjacent bowel, so the approach and any structures taken down to reach the space matter for documentation. This code applies when the retroperitoneal space itself, rather than one of its contained organs, is the object of the examination.
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
A code from this family applies when the documentation describes exploring or examining a general anatomical region visually or manually, with no other definitive procedure performed on that same body part during the same operative encounter. If the physician inspects the region and then proceeds to treat what is found - excising a mass, draining fluid, or repairing a defect - coding conventions generally hold that only the more definitive procedure is coded, since inspection is considered inherent to it.
The most common assignment error is separately coding an inspection that was simply part of gaining access to perform another procedure on the same body part; this is not separately reportable. Inspection should only be coded on its own when it is truly the sole procedure performed, or when it involves a different body part than the one that was treated during the same operative episode.
Commonly Confused With
Inspection is frequently confused with procedures that include exploration as a preliminary step, such as excision or extirpation, where the inspection is bundled into the definitive root operation rather than coded separately. It differs from a diagnostic biopsy captured under excision, since inspection alone involves no tissue removal. When an endoscope or scope is used purely to look without treating, inspection is correct; once any therapeutic action is taken through that same access, the corresponding root operation for that action takes precedence.
