What 50240 covers

A urologist removes a portion of the kidney through open surgical exposure, aiming to treat a localized lesion while retaining the uninvolved kidney. A common setting is surgery for a renal mass when partial resection is appropriate. The operation may include work to control bleeding and repair the remaining kidney and collecting system as needed. This is the open procedure; laparoscopic partial nephrectomy is a different code.

Select the code when the operative report supports partial removal rather than removal of the entire kidney. Document the side, open approach, indication, extent of tissue removed, and that kidney tissue was retained. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

Both describe partial kidney surgery, but 50543 is the laparoscopic approach; 50240 is the open operation.
50220Kidney removalOpen, nonradical removal
50220 represents open removal of the whole kidney. Use 50240 when a portion is removed and kidney tissue remains.
50250Renal cryoablationOpen surgical approach
50250 treats renal mass tissue by open cryosurgical ablation. 50240 removes a portion of the kidney surgically.

50240 billing questions

How does this differ from laparoscopic partial nephrectomy?

This code is for the open operation. Laparoscopic partial nephrectomy is reported with 50543.

When should a total nephrectomy code be used instead?

Use a total nephrectomy code when the entire kidney is removed. This code describes an operation that leaves part of the kidney in place.

Are routine steps of the partial nephrectomy separately reported?

Routine exposure, removal of the target tissue, bleeding control, and closure are part of the operation, not separate kidney procedures.

How is bilateral surgery reported?

CMS identifies this as a bilateral procedure: modifier 50 is paid at 150%.

What documentation supports the code and assistant or co-surgeon billing?

The operative report should establish the open approach, side, indication, and partial rather than total removal. An assistant at surgery may be paid; co-surgeons require supporting documentation.
