ICD-10: C79.10

The ICD-10 code C79.10 refers to a secondary malignant neoplasm of unspecified urinary organs. This classification is part of the broader category of secondary malignant neoplasms, which are tumors that have metastasized from a primary cancer site to other areas of the body, in this case, the urinary system.

Clinical Description

Definition

Secondary malignant neoplasms occur when cancer cells spread from their original (primary) site to other parts of the body. The urinary organs include the kidneys, ureters, bladder, and urethra. When the specific site of the secondary neoplasm within the urinary system is not identified, it is classified under C79.10.

Clinical Presentation

Patients with secondary malignant neoplasms in the urinary organs may present with a variety of symptoms, which can include:

• Hematuria: Blood in the urine, which may be visible or detected through testing.
• Urinary obstruction: This can lead to symptoms such as flank pain, changes in urinary habits, or urinary retention.
• Pain: Patients may experience pain in the lower abdomen or back, depending on the location of the neoplasm.
• Weight loss and fatigue: General symptoms associated with cancer may also be present.

Diagnosis

Diagnosis typically involves a combination of imaging studies (such as CT scans or MRIs) and biopsy procedures to confirm the presence of malignant cells. The specific origin of the primary cancer should also be identified, as this can influence treatment options and prognosis.
