ICD-10 Code C67.9 – Malignant neoplasm of bladder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C67.9 – Malignant neoplasm of bladder, unspecified
What it is
This code identifies a malignant tumor arising in the bladder when the record does not specify the exact bladder site. Use it for confirmed bladder cancer with no further anatomic detail.
Clinical signs
Common findings include hematuria, urinary frequency, urgency, or dysuria. Clinical features vary; refer to documentation and pathology when available.
When to use this code
Use C67.9 when the provider documents bladder cancer but does not identify trigone, dome, lateral wall, or another specific location. It also fits when the diagnosis is confirmed, but the site detail is unavailable in the chart.
Choose this code only after reviewing operative notes, pathology, and imaging for a more precise bladder site. If the record names a specific bladder subsite, code that instead.
Do not use for
Do not use this code for benign bladder tumors, bladder polyps, or suspected cancer without confirmation. Check documentation if the malignancy is described as secondary or metastatic from another primary site.
Coding tip
Always look for a documented bladder subsite before assigning C67.9, because more specific codes may be available.
