ICD-10 Code D30.00 – Benign neoplasm of unspecified kidney (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.00 – Benign neoplasm of unspecified kidney
What it is
D30.00 identifies a noncancerous tumor in a kidney when the side is not documented. Use it when the record supports a benign renal neoplasm but does not specify right or left.
Clinical signs
Clinical features vary; refer to documentation. Benign renal masses may be found incidentally on imaging or during evaluation of hematuria, flank pain, or a palpable mass, but these findings are not specific.
When to use this code
Use this code when the provider documents a benign neoplasm of the kidney and the laterality is unknown, unspecified, or not recorded. It also fits when imaging or pathology confirms a benign renal tumor without side designation. If the note names a specific benign histology or a different renal condition, code that documented diagnosis instead.
Do not use for
Do not use D30.00 for malignant kidney tumors, renal cysts, or inflammatory kidney disease. Check documentation if the mass is described as suspicious, indeterminate, or not yet diagnosed.
Coding tip
Query for laterality and exact pathology when available, because a more specific kidney code may apply.
