Benign neoplasm of right renal pelvis

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

This code is appropriate for documenting a confirmed benign neoplasm located specifically in the right renal pelvis, often identified through imaging studies like CT scans or MRI, and sometimes confirmed by biopsy. Use this code when the pathology report definitively states a benign nature and the laterality is right-sided.

• Ensure documentation clearly specifies "benign" and "right renal pelvis" to avoid miscoding as a malignant or unspecified neoplasm.
• Distinguish from benign neoplasms of the kidney parenchyma (e.g., D30.0x) or left renal pelvis (D30.12).
• If the neoplasm is of uncertain behavior or unknown laterality, a more appropriate code from category D39 or D49 would be necessary.
