ICD-10 Code D30.21 – Benign neoplasm of right ureter (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.21 – Benign neoplasm of right ureter
What it is
D30.21 identifies a noncancerous tumor located in the right ureter. Use it when documentation clearly states a benign neoplasm involving that specific ureteral side.
Clinical signs
Clinical features vary; refer to documentation. Patients may have urinary obstruction, hematuria, or flank discomfort, but the code is based on the documented diagnosis, not symptoms alone.
When to use this code
Use D30.21 when the provider documents a benign neoplasm of the right ureter, such as a confirmed benign mass on imaging, pathology, or operative report. Assign it only when the right-sided ureteral site is specified. If the record says ureteral tumor without laterality or benign status, check documentation.
Do not use for
Do not use this code for malignant ureteral neoplasms, unspecified ureteral masses, or benign disease in the left ureter. If the documentation is unclear, check documentation rather than guessing.
Coding tip
Always verify both histology and laterality before assigning D30.21.
