About 50081: Complex percutaneous kidney stone removal
Percutaneous nephrolithotomy for renal or pelvic stones larger than 2 cm, reported when the surgeon fragments and removes stones through a kidney access tract.
A urologist uses an access tract through the flank to reach the kidney or renal pelvis, then fragments and removes a stone burden larger than 2 cm. The operation is typically performed in an operating room, often for large or complex renal stones that require percutaneous rather than ureteroscopic treatment. The procedure may involve nephroscopic inspection and stone extraction as well as lithotripsy.
Select this code when the documented stone size exceeds 2 cm; code 50080 is the related choice for stones up to 2 cm. The operative report should establish stone size, location, laterality, the percutaneous approach, and the fragmentation or removal performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 identifies bilateral surgery and is paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team-surgery billing is not permitted.
