What 88375 covers

Optical endomicroscopy produces microscopic images of tissue in a clinical setting, commonly during gastrointestinal endoscopy. The physician reviews real-time or recorded images to assess cellular and tissue features and prepares an interpretation and report. This is image-based assessment, distinct from examining a removed specimen on a conventional pathology slide.

Report 88375 for the professional interpretation and report, not for acquiring the images or furnishing the equipment and other technical work. CMS identifies this as a professional-component-only code; a separate code covers the technical portion. Documentation should identify the optical endomicroscopy study, the images reviewed, the physician’s findings, and the resulting interpretation. When optical endomicroscopy is performed as part of an endoscopic procedure, the endoscopy code describes that procedure; 88375 represents the separately coded interpretation service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
