ICD-10 Code C67.3 – Malignant neoplasm of anterior wall of bladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C67.3 – Malignant neoplasm of anterior wall of bladder
What it is
C67.3 identifies a malignant tumor located on the anterior wall of the urinary bladder. Use it when the documentation specifies that exact bladder wall site.
Clinical signs
Clinical features vary; refer to documentation. Bladder cancer is often associated with hematuria, urinary urgency, frequency, dysuria, or pelvic discomfort, but site-specific findings may not be distinct.
When to use this code
Use C67.3 when the provider documents primary bladder cancer in the anterior wall. It is appropriate for confirmed malignancy, whether newly diagnosed or under active evaluation, if the anatomic site is clearly stated.
If the record says only “bladder cancer” or names another bladder location, you should not assign this code. Check documentation for the exact site before coding.
Do not use for
Do not use C67.3 for benign bladder lesions, uncertain masses, or malignant neoplasms in other bladder walls. Check documentation if the site is described as overlapping or unspecified.
Coding tip
Always code the exact bladder subsite documented, because laterality does not apply but location does.
