ICD-10 Code D30.11 – Benign neoplasm of right renal pelvis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.11 – Benign neoplasm of right renal pelvis
What it is
This code identifies a noncancerous tumor located in the right renal pelvis, the area where urine collects before entering the ureter. Use it when documentation clearly states a benign neoplasm in that specific site.
Clinical signs
Clinical features vary; refer to documentation. Findings may be incidental on imaging or evaluation for hematuria, flank pain, or urinary obstruction, but the diagnosis must be confirmed as a benign neoplasm of the right renal pelvis.
When to use this code
Use D30.11 when the provider documents a benign tumor, mass, or neoplasm of the right renal pelvis and there is no indication of malignancy. It also fits when pathology, imaging, or operative notes localize the lesion to that site. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code for malignant renal pelvis tumors, unspecified renal pelvis lesions, or benign neoplasms in the left renal pelvis or other urinary tract sites. Check documentation if laterality or behavior is not stated.
Coding tip
Verify both behavior and laterality; right renal pelvis must be documented, not inferred from a general kidney mass.
