ICD-10 Code D30.02 – Benign neoplasm of left kidney (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.02 – Benign neoplasm of left kidney
What it is
D30.02 identifies a noncancerous growth arising in the left kidney. It indicates a benign renal neoplasm, not a malignant tumor or metastatic disease.
Clinical signs
Clinical features vary; refer to documentation. Benign renal masses may be found incidentally on imaging, or noted during evaluation of flank pain, hematuria, or a renal mass.
When to use this code
Use D30.02 when the provider documents a benign neoplasm of the left kidney, including a confirmed benign renal mass. Use it when the lesion is specifically identified as left-sided. If the record only says “renal mass” or “kidney lesion,” check documentation.
Do not use for
Do not use this code for malignant kidney tumors, unspecified renal masses, or cysts without a neoplasm diagnosis. Check documentation if the laterality or benign nature is not clearly stated.
Coding tip
Confirm both benign behavior and left kidney laterality before assigning D30.02.
