ICD-10 Code D30.10 – Benign neoplasm of unspecified renal pelvis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.10 – Benign neoplasm of unspecified renal pelvis
What it is
D30.10 identifies a noncancerous growth in the renal pelvis, the part of the kidney that collects urine before it enters the ureter. Use it when documentation states a benign neoplasm and the side is not specified.
Clinical signs
Clinical features vary; refer to documentation. Patients may have no symptoms, or imaging may show a renal pelvis mass that appears benign without evidence of invasion or metastasis.
When to use this code
Use this code when the provider documents a benign neoplasm of the renal pelvis and does not identify right or left side. It also fits pathology or imaging reports describing a nonmalignant renal pelvis lesion. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use D30.10 for malignant renal pelvis tumors, uncertain behavior, or lesions documented as cysts, stones, or inflammatory masses. Do not assume laterality when the record does not support it.
Coding tip
Confirm that the note specifically says “benign neoplasm” and “unspecified renal pelvis” before coding.
