CPT code 43273 identifies endoscopic visualization of one or more pancreatic or common bile ducts performed as part of a separately reportable endoscopic retrograde cholangiopancreatography (ERCP). This diagnostic maneuver is clinically important for evaluating ductal anatomy, diagnosing obstructive or inflammatory ductal disease, and guiding therapeutic decision-making during ERCP procedures. Nationally, CPT code 43273 is relevant for hospital outpatient departments and ambulatory endoscopy centers where ERCPs are commonly performed.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical role, typical sites of service, and the payer landscape. The publication also provides benchmarks and policy context relevant to billing and coverage of ERCP-related diagnostic visualization, highlights common billing considerations, and summarizes recent policy updates that affect national reimbursement and documentation expectations. Practical clinical context clarifies when the visualization component is reportable separately during ERCP and how it fits into the overall procedure workflow.
