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

Lower Jaw

Inspection of the lower jaw covers examination of the mandible and its associated soft tissue, commonly performed to assess fractures, dislocations, infection, or tumor involvement, since the mandible is the only mobile bone of the facial skeleton and bears significant functional load during chewing and speech. Its curved structure and proximity to the inferior alveolar nerve make careful visual or manual assessment relevant before any reduction, fixation, or resection is planned, and inspection may be done externally or through an existing wound or incision. This code applies at the general regional level when the mandible is examined as a whole rather than through a named component procedure, and documentation should describe the reason for inspection, such as suspected fracture or abscess.

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.
