CMS’ proposed 2027 Hospital Outpatient Prospective Payment System (HOPPS) and Ambulatory Surgical Center (ASC) payment rule includes several changes that could significantly affect gastroenterology practices and ASCs. While overall ASC payments would increase modestly, many high-volume GI procedures would face reimbursement cuts, continuing financial pressure on endoscopy services.
Among the six highest-spending ASC specialties, gastroenterology is one of only two projected to receive lower payments, with an estimated 2% reduction in aggregate reimbursement for 2027. High-volume procedures such as colonoscopy with lesion removal, colonoscopy with biopsy, and esophagogastroduodenoscopy (EGD) with biopsy are each expected to see approximately 2% payment cuts, despite remaining among the highest-reimbursed GI services.
