ICD-10 Code D30.3 – Benign neoplasm of bladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D30.3 – Benign neoplasm of bladder
What it is
D30.3 identifies a noncancerous growth arising in the bladder. Use it when documentation states a benign bladder tumor or polypoid lesion that is not described as malignant or in situ.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include hematuria, urinary frequency, dysuria, or a bladder mass seen on cystoscopy or imaging.
When to use this code
Use D30.3 when the provider documents a benign neoplasm of the bladder, including pathology-confirmed benign tumors. It may also fit a cystoscopic or imaging diagnosis when the record clearly identifies the lesion as benign. If the note is unclear, check documentation before coding.
Do not use for
Do not use this code for malignant bladder tumors, carcinoma in situ, or nonspecific bladder lesions without a benign diagnosis. Check documentation if the record only says “mass,” “lesion,” or “growth.”
Coding tip
Code the documented bladder site only when the provider specifically identifies the lesion as benign.
