G0342 Islet cell transplant Medicare reimbursement rates in Massachusetts

This service covers laparoscopic delivery of pancreatic islet cells for transplantation. A common clinical setting is autologous islet transplantation after pancreatectomy for chronic pancreatitis, with the islets infused into the portal circulation. A surgeon performs the laparoscopic portion in an operating room; the operative record should identify the laparoscopic approach and describe the transplant procedure performed.

Select this code when the islet transplantation is performed laparoscopically, rather than by percutaneous access or laparotomy. Documentation should establish the approach and the transplant work, including the operative context and islet delivery. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care through day 90. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted. Modifier 50 is not appropriate for this procedure.
