2025 ICD-10-CM code C68.8
(Active) Effective Date: N/A Neoplasms - Malignant neoplasms of urinary tract (C64-C68) 2: Neoplasms (C00-D49) Feed
Malignant neoplasm of overlapping sites of the urinary organs. Primary malignant neoplasm of two or more contiguous sites of urinary organs whose point of origin cannot be determined.
Medical necessity for procedures related to C68.8 is established by the presence of the malignant neoplasm affecting multiple urinary system sites.The documentation should support the need for diagnostic testing and treatment based on the patient's specific clinical presentation and the extent of the disease.
Clinicians diagnosing C68.8 consider patient history, reported symptoms, physical examination findings, and results from laboratory and imaging tests.Urinalysis, biopsies, ultrasound, CT, MRI, intravenous pyelogram, PET scans, and cystoscopy may be used. Treatment options, including surgery, chemotherapy, and radiation, are determined based on the stage and severity of the cancer.
- 2: Neoplasms (C00-D49)
- Malignant neoplasms (C00-C96)Malignant neoplasms, stated or presumed to be primary (of specified sites), and certain specified histologies, except neuroendocrine, and of lymphoid, hematopoietic and related tissue (C00-C75)Malignant neoplasms of urinary tract (C64-C68)
In simple words: This code describes a cancer that involves multiple parts of the urinary system, like the kidneys, bladder, or tubes connecting them, and it's difficult to tell exactly where the cancer started.
Malignant neoplasm of overlapping sites of the urinary organs refers to cancerous growth affecting multiple adjacent areas within the urinary system.The exact origin of the malignancy within the urinary organs cannot be definitively identified.
Example 1: A patient presents with symptoms suggestive of bladder cancer but imaging reveals a tumor involving both the bladder and the adjacent urethra, making it difficult to determine the primary site. C68.8 would be used., A patient has a cancerous mass affecting both kidneys.Biopsies and imaging are inconclusive in determining a single origin point.C68.8 is appropriate., A tumor is found extending across the ureter and into the renal pelvis of the kidney, making it challenging to determine the exact starting location of the malignancy. C68.8 is applied.
Documentation for C68.8 should clearly describe the involvement of multiple contiguous sites within the urinary system. Results from imaging studies, biopsies, and other diagnostic tests should be included to support the diagnosis.The inability to pinpoint a single primary site of origin should be explicitly stated in the clinical documentation.
