ICD-10 Code D30.0 – Benign neoplasm of kidney (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.0 – Benign neoplasm of kidney
What it is
D30.0 identifies a noncancerous growth arising in the kidney. Use it when documentation states a benign renal neoplasm, not a malignant tumor or an unspecified kidney mass.
Clinical signs
Clinical features vary; refer to documentation. These lesions may be found incidentally on imaging or evaluated because of flank pain, hematuria, or a renal mass noted during workup.
When to use this code
Use D30.0 when the provider documents a benign tumor of the kidney, such as a clearly identified nonmalignant renal neoplasm. It is also appropriate when pathology or imaging supports a benign renal mass and the record specifies the kidney as the site. If the diagnosis is uncertain, check documentation before assigning this code.
Do not use for
Do not use D30.0 for malignant kidney tumors, renal cysts, or nonspecific “kidney mass” findings without confirmation of benign neoplasm. Check documentation if the site or behavior is unclear.
Coding tip
Code the documented behavior and site exactly; if the record only says “renal lesion,” query for clarification.
