Summary & Overview
CPT 43202: Upper Endoscopy with Biopsy
CPT code 43202 designates an upper endoscopic procedure in which a flexible endoscope is passed through the mouth and one or more tissue biopsies are obtained. This code captures a common diagnostic intervention used to evaluate upper gastrointestinal symptoms and to obtain tissue for histologic diagnosis. Nationally, endoscopic biopsy procedures are important drivers of outpatient procedural volume and pathology utilization, and they carry implications for facility readiness, anesthesia services, and pathology billing.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, typical sites of service, and the kinds of documentation elements that support coding. The publication summarizes common reimbursement considerations, claims coding practices, and areas where policy updates or payer-specific edits frequently affect payment. It also provides benchmarks for utilization and opportunities to align clinical documentation with coding requirements. Data not available in the input are noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 57-year-old patient presents to a gastroenterology clinic with progressive odynophagia and dysphagia and an upper endoscopic evaluation is scheduled. The provider performs a flexible esophagogastroduodenoscopy (EGD) via the mouth under moderate sedation. During inspection of the esophagus and proximal stomach, an irregular lesion is identified and the endoscopist obtains one or more mucosal biopsies using biopsy forceps passed through the working channel of the flexible endoscope. Specimens are placed in appropriate fixative and submitted to pathology for histologic evaluation. Typical site of service is an outpatient endoscopy suite or hospital ambulatory surgery unit. The clinical workflow includes pre-procedure history and consent, sedation and monitoring, procedure documentation including number and location of biopsy specimens, specimen labeling and handling, and post-procedure recovery and discharge instructions.
