ICD-10 Code C67 – Malignant neoplasm of bladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C67 – Malignant neoplasm of bladder
What it is
C67 identifies a malignant tumor arising in the bladder. Use it when the documentation states bladder cancer or malignant neoplasm of the bladder, without a more specific subsite.
Clinical signs
Common findings include hematuria, urinary frequency, urgency, dysuria, or pelvic discomfort. Clinical features vary; refer to documentation and pathology or imaging when available.
When to use this code
Use C67 when the provider documents primary bladder malignancy and does not specify a more detailed site or histology. It is also appropriate for confirmed bladder cancer under evaluation, if the record supports the diagnosis. Code the documented bladder site as precisely as possible when available.
Do not use for
Do not use this code for benign bladder tumors, bladder polyps, or non-neoplastic urinary symptoms alone. Check documentation if the lesion is described as metastatic, uncertain, or arising outside the bladder.
Coding tip
Verify whether the note identifies a specific bladder subsite, because a more detailed C67 code may be needed.
