CPT® Code 43273

Add-On Code

Endoscopic cannulation of papilla with direct visualization of pancreatic/common bile duct(s) (List separately in addition to code(s) for primary procedure)

The procedure described by CPT® Code 43273 involves the endoscopic cannulation of the papilla, which is a critical step in the evaluation of the pancreatic and common bile ducts. This procedure is performed with direct visualization, allowing healthcare professionals to assess these ducts for any abnormalities or conditions that may not be visible through standard radiographic imaging techniques. The endoscopic cannulation is typically conducted during an endoscopic retrograde cholangiopancreatography (ERCP), which is a more comprehensive procedure aimed at diagnosing and treating conditions related to the biliary and pancreatic systems. During the procedure, a duodenoscope is utilized, which is a specialized endoscope designed to navigate through the gastrointestinal tract, specifically reaching the duodenum where the papilla of Vater is located. The physician inserts a catheter through the duodenoscope to inject contrast material into the ducts, enabling fluoroscopic imaging to visualize the anatomy and any potential obstructions or pathologies. Following this, a guidewire is advanced through the scope to facilitate further examination of the biliary tree. The procedure is essential for identifying diseases such as strictures, stones, or tumors within the ducts, thereby guiding subsequent therapeutic interventions.
