Benign neoplasm of kidney, except pelvis

This code signifies the presence of a non-cancerous growth within the kidney tissue itself, excluding the renal pelvis. These benign tumors are typically slow-growing and do not metastasize to other parts of the body. Examples include renal adenomas, fibromas, or lipomas.

Use this code when diagnostic imaging (e.g., ultrasound, CT, MRI) or biopsy confirms a benign renal mass located anywhere in the kidney parenchyma, but not involving the renal pelvis. Documentation should clearly state "benign neoplasm" or a specific benign tumor type of the kidney.

• Differentiate carefully between benign and malignant renal neoplasms; malignant tumors of the kidney have distinct codes.
• Ensure the documentation specifies "except pelvis" or clearly indicates the mass is within the renal parenchyma.
• Do not use this code for benign neoplasms of the renal pelvis (e.g., papilloma of renal pelvis), which are classified elsewhere.
