ICD-10 Code C67.6 – Malignant neoplasm of ureteric orifice (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C67.6 – Malignant neoplasm of ureteric orifice
What it is
C67.6 identifies a malignant tumor arising in the ureteric orifice, the area where the ureter opens into the bladder. Use it when documentation specifies cancer at this bladder location.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include hematuria, urinary obstruction, or symptoms related to bladder tumor involvement, but the diagnosis should be supported by pathology or imaging.
When to use this code
Use C67.6 when the provider documents primary malignancy of the ureteric orifice, including a bladder tumor centered at that site. It also applies when the record clearly identifies cancer involving the ureteral opening. If the location is unclear, check documentation.
Do not use for
Do not use this code for benign bladder lesions, ureter cancer outside the orifice, or metastatic disease to the bladder without primary ureteric orifice involvement. Check documentation if the site is ambiguous.
Coding tip
Verify the exact anatomic site in the operative note, pathology report, or imaging before assigning C67.6.
