Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 49421 covers

This procedure establishes access for peritoneal dialysis, often for a patient preparing to begin home dialysis. A surgeon makes an incision to place the catheter into the peritoneal cavity and routes part of it through a tunnel beneath the skin. The procedure is commonly performed in an operating room. The open approach, rather than the need for dialysis alone, distinguishes this service from percutaneous catheter placement.

Report 49421 when the operative note supports open insertion, intraperitoneal catheter placement, and creation of the subcutaneous tunnel. A catheter placed percutaneously or one connected to an implanted subcutaneous port calls for a different code. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. If other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery for this code and does not permit co-surgeons or team surgery.
