Summary & Overview
CPT 88375: Endomicroscopic Imaging Interpretation (Optical Biopsy)
CPT code 88375 designates the pathology interpretation and report for endomicroscopic imaging, often called an optical biopsy. This code captures the expert diagnostic input of a qualified provider, usually a pathologist, who interprets real-time or referred endomicroscopy performed by an endoscopist. Nationally, 88375 is relevant as endomicroscopy gains clinical traction for targeted, in vivo microscopic evaluation during endoscopic procedures, affecting coding, documentation, and coverage considerations.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for endomicroscopic interpretation, common billing considerations tied to this service, and what to expect from major national payers. The publication summarizes benchmarks where available, highlights policy and coverage themes, and outlines operational implications for reporting and documentation. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 88375 describes an interpretation and reporting service provided by a qualified provider, typically a pathologist, for real-time or referred endomicroscopic imaging. This service documents an expert review of endomicroscopy—also called an optical biopsy—performed by an endoscopist.
-
Service type: Diagnostic interpretation and pathology consultation for endomicroscopic imaging
-
Typical site of service: Endoscopy suite or hospital-based endoscopy unit where an endoscopist performs endomicroscopic imaging and a pathologist provides real-time or deferred interpretation.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of chronic gastroesophageal reflux disease and a recently detected suspicious mucosal lesion on high-definition endoscopy is referred for endomicroscopic imaging performed during upper endoscopy. The endoscopist performs probe-based confocal laser endomicroscopy (pCLE) during the esophagogastroduodenoscopy to obtain in vivo, real-time microscopic assessment of the lesion to guide targeted biopsy and immediate management decisions. A pathologist with expertise in endomicroscopy remotely or contemporaneously interprets the live imaging and issues a formal report documenting the optical biopsy findings, correlation with endoscopic appearance, and recommendations for tissue sampling if needed. Typical workflow includes pre-procedure informed consent, administration of topical or intravenous contrast agents as indicated, endomicroscopic imaging acquisition by the endoscopist, real-time image transmission or referral to the interpreting pathologist, and final interpretive report filed in the medical record. Typical site of service is an ambulatory endoscopy suite or hospital endoscopy unit. The service is billed by the interpreting qualified provider for the interpretation and report of the endomicroscopic imaging.
