ICD-10 Code D30.20 – Benign neoplasm of unspecified ureter (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.20 – Benign neoplasm of unspecified ureter
What it is
D30.20 identifies a noncancerous growth in the ureter when the side or exact ureter is not documented. Use it for benign tumors arising in the tube that carries urine from the kidney to the bladder.
Clinical signs
Clinical features vary; refer to documentation. Findings may include urinary obstruction, hematuria, flank pain, or an incidental mass on imaging, but the diagnosis should be supported by provider documentation of a benign ureteral neoplasm.
When to use this code
Use D30.20 when the record states a benign neoplasm of the ureter and does not specify right or left side. It also fits when pathology, imaging, or a specialist note confirms a benign ureteral tumor and laterality is unavailable. Check documentation if the lesion is described only as a ureteral mass.
Do not use for
Do not use this code for malignant ureter tumors, ureteral polyps without neoplasm documentation, or inflammatory narrowing of the ureter. If the side is known, select the laterality-specific code instead.
Coding tip
Confirm whether the provider documented benign behavior and whether laterality is missing before assigning D30.20.
