ICD-10 Code C67.5 – Malignant neoplasm of bladder neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C67.5 – Malignant neoplasm of bladder neck
What it is
C67.5 identifies a malignant tumor arising in the bladder neck, the area where the bladder narrows into the urethra. Use it when the record clearly documents cancer in this specific bladder location.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include hematuria, urinary frequency, urgency, or obstructive urinary symptoms, but the diagnosis should be based on documented malignancy.
When to use this code
Use C67.5 when the provider documents primary cancer of the bladder neck or a malignant neoplasm centered in that anatomic site. It is appropriate for confirmed diagnoses in inpatient, outpatient, and pathology-supported records. If the note only says “bladder cancer” without location, check documentation.
Do not use for
Do not use this code for benign bladder lesions, carcinoma in situ, or malignant disease documented in another bladder site. If the tumor location is unclear or conflicts with the record, check documentation.
Coding tip
Code the exact anatomic site only when the documentation supports it; otherwise query for clarification before assigning C67.5.
