ICD-10 Code C68 – Malignant neoplasm of other and unspecified urinary organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C68 – Malignant neoplasm of other and unspecified urinary organs
What it is
C68 identifies a malignant neoplasm arising in urinary organs not otherwise specified in the ICD-10-CM category. Use it when the record confirms cancer of an urinary organ, but the exact site is not named.
Clinical signs
Clinical features vary; refer to documentation. Common findings in urinary tract malignancy may include hematuria, urinary obstruction, pain, or an imaging or biopsy report confirming a malignant lesion.
When to use this code
Use C68 when the provider documents a malignant tumor of an other or unspecified urinary organ and no more specific urinary site is available. It also fits when the chart supports cancer in this category but does not identify bladder, kidney, ureter, or renal pelvis.
If later documentation names the exact organ, code the more specific site instead. Check documentation for primary versus secondary malignancy, because that may change code selection.
Do not use for
Do not assign C68 for benign tumors, carcinoma in situ, or cancers with a clearly documented specific urinary site. Do not use it when the record only says “urinary symptoms” without a confirmed malignancy.
Coding tip
Query the provider when the urinary organ is unclear, because specificity often changes the final code.
