Visually and/or manually exploring a body part

Procedure Overview

Inspection procedures involve a surgeon visually or manually examining a lymphatic or hemic structure - a node, the spleen, the thymus, or bone marrow - without taking a biopsy sample or performing any other definitive treatment during that look. This might be done through a scope inserted through a small incision, during an open procedure before deciding on further steps, or by manual palpation during another operation.

The purpose is diagnostic: confirming the extent of disease, checking for spread before staging a cancer, or evaluating an organ's appearance and size when imaging alone hasn't given a clear answer. Splenoscopy to assess the spleen before deciding on splenectomy is one recognizable example.

Because Inspection captures exploration alone, if the surgeon goes on to biopsy, remove, or otherwise treat what they find, that additional step is coded using whatever root operation matches the treatment performed, in addition to or instead of the inspection depending on PCS coding guidelines.

Anatomy & Axis Detail

Bone Marrow

Inspection of bone marrow refers to direct visual or manual examination of marrow tissue, most typically performed during an open surgical procedure on bone where marrow is exposed incidentally, or as part of a broader hematologic workup requiring direct assessment beyond percutaneous sampling. Because marrow is distributed throughout medullary cavities rather than confined to one anatomic site, this code uses a general body part value rather than referencing a specific bone. Inspection is coded separately from marrow aspiration or biopsy, which extracts tissue for laboratory analysis rather than simply visualizing it, and it is often a secondary finding during procedures whose primary intent lies elsewhere in the skeletal or hematologic system.

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 needs to show a body part was examined visually or manually without any accompanying excision, extirpation, drainage, or other definitive action taken on it during that same look. If the same operative approach also included a biopsy or other treatment of the identical body part, PCS guidelines generally direct coders to code only the more definitive procedure rather than adding a separate Inspection code.

The recurring mistake is coding Inspection alongside a biopsy or excision of the same structure when only the definitive procedure should be captured, or failing to code Inspection at all when a diagnostic laparoscopy or exploration was performed and nothing further was done because the findings didn't warrant treatment.

Commonly Confused With

Inspection is most often confused with the definitive root operations - Excision, Extirpation, Drainage - performed during the same case; the distinguishing question is always whether something was actually removed or treated versus just examined. It's also distinct from imaging-based diagnostic studies coded outside the Medical and Surgical section, since Inspection specifically requires a surgical approach, whether open, percutaneous, or via a natural or artificial opening, to view or palpate the structure directly.
