Clinical & Coding Specifications
Clinical Context
A patient presents to the outpatient hospital setting for a colonoscopy due to a history of colon polyps or abnormal findings on prior screening. During the procedure, the gastroenterologist identifies a lesion or area requiring treatment and performs a directed submucosal injection (such as saline, epinephrine, or another substance) to aid in polyp removal, control bleeding, or mark a site for future intervention. The workflow involves pre-procedure assessment, colonoscopy with submucosal injection, and post-procedure monitoring. This service is typically performed by a gastroenterology physician, but may also be provided by family medicine or internal medicine physicians with appropriate training.
