Benign neoplasm of renal pelvis

This code signifies the presence of a non-cancerous growth originating in the renal pelvis, the funnel-shaped part of the kidney that collects urine. These benign neoplasms are typically slow-growing and do not metastasize to other parts of the body.

Assign this code when documentation clearly identifies a benign tumor or mass located specifically within the renal pelvis. This is appropriate for conditions such as benign papilloma or fibroma of the renal pelvis, confirmed by pathology or imaging.

• Ensure documentation specifies "benign" and "renal pelvis" to differentiate from malignant or other kidney locations.
• Do not use for malignant neoplasms of the renal pelvis (e.g., transitional cell carcinoma), which have separate codes.
• Consider additional codes for any associated symptoms or complications, if documented.
