ICD-10 Code D30.12 – Benign neoplasm of left renal pelvis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.12 – Benign neoplasm of left renal pelvis
What it is
D30.12 identifies a noncancerous tumor in the left renal pelvis, the collecting area where urine drains from the left kidney. Use this code when documentation states a benign neoplasm in that specific location.
Clinical signs
Clinical features vary; refer to documentation. Benign renal pelvis lesions may be found on imaging, cystoscopy, or pathology, and may be associated with hematuria, obstruction, or incidental detection.
When to use this code
Use D30.12 when the provider documents a benign neoplasm of the left renal pelvis or confirms a benign mass in that site. It is appropriate for confirmed pathology, imaging-supported diagnosis, or a clearly stated clinical assessment. Check documentation if the laterality or site is unclear.
Do not use for
Do not use this code for malignant renal pelvis tumors, unspecified renal pelvis neoplasms, or benign lesions in the right kidney or ureter. If the record only says “kidney mass,” you need a more specific diagnosis.
Coding tip
Verify both benign behavior and left renal pelvis location before assigning D30.12.
