ICD-10 Code D30.1 – Benign neoplasm of renal pelvis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.1 – Benign neoplasm of renal pelvis
What it is
D30.1 identifies a noncancerous tumor arising in the renal pelvis, the collecting area where urine drains from the kidney. Use it when the record clearly documents a benign neoplasm in this site.
Clinical signs
Clinical features vary; refer to documentation. Patients may have hematuria, flank pain, or an incidental imaging finding, but the diagnosis should be supported by clinician documentation or pathology.
When to use this code
Use D30.1 when the provider documents a benign neoplasm of the renal pelvis, including cases confirmed by imaging, endoscopy, or histology. It is also appropriate for follow-up care when the documented diagnosis remains active. Check documentation if the lesion is described only as a mass or lesion without a benign neoplasm diagnosis.
Do not use for
Do not use this code for malignant renal pelvis tumors, urothelial carcinoma, or unspecified urinary tract masses. If the site or behavior is unclear, check documentation before assigning D30.1.
Coding tip
Verify both the benign behavior and the renal pelvis site; a renal parenchymal or ureteral lesion is coded elsewhere.
