ICD-10 Code C67.1 – Malignant neoplasm of dome of bladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C67.1 – Malignant neoplasm of dome of bladder
What it is
C67.1 identifies a malignant neoplasm located in the dome of the urinary bladder. Use it when documentation specifies this bladder site and confirms cancer.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include hematuria, urinary irritation, or a bladder mass confirmed by imaging, cystoscopy, or pathology.
When to use this code
Use C67.1 when the provider documents primary bladder cancer arising in the dome. It also fits pathology or operative reports that clearly name the dome as the tumor site. If the site is unclear, check documentation before coding.
Do not use for
Do not use this code for benign bladder lesions, metastatic disease to the bladder, or malignancy in another bladder site. Check documentation if the record only says “bladder cancer” without a specific location.
Coding tip
Confirm both malignancy and exact anatomic site in the final report before assigning C67.1.
