C64.2 Malignant neoplasm of left kidney, except renal pelvis

Name of the Condition

• Malignant neoplasm of left kidney, except renal pelvis
• Commonly referred to as left kidney cancer or left renal cell carcinoma.

Summary

This condition refers to a cancerous growth in the left kidney tissue that excludes the renal pelvis. The cancer can interfere with the kidney's ability to filter waste and balance fluids. It may spread to nearby tissues or other parts of the body if left untreated.

Causes

The exact cause of kidney cancer is not fully understood. However, factors like genetic mutations, lifestyle choices (e.g., smoking), and certain inherited conditions may contribute to its development.

Risk Factors

• Risk factors include being over 50 years old, smoking, obesity, hypertension, certain hereditary conditions (e.g., von Hippel-Lindau disease), and prolonged use of certain pain medications.

Symptoms

• Symptoms might include blood in urine, persistent pain in the back or side, unexplained weight loss, fatigue, and a lump or mass in the kidney area.

Diagnosis

Diagnosis typically involves a combination of approaches such as imaging tests (CT or MRI scans), blood tests, urine tests, and possibly a biopsy to examine the kidney tissue.

Treatment Options

• Treatment options range from surgery (nephrectomy) to remove the tumor or entire kidney, to targeted therapies and immunotherapy. Radiation and chemotherapy may also be used in specific cases.

Prognosis and Follow-Up

Prognosis depends on the stage at diagnosis, tumor characteristics, and overall health. Regular follow-up with imaging and blood tests is often recommended to monitor for recurrence or metastasis.

Complications

Complications can include metastasis to other organs, kidney failure, or side effects from treatment such as infection or bleeding.

Lifestyle & Prevention

• Maintaining a healthy weight, avoiding smoking, and managing blood pressure may help reduce risk. Regular check-ups are advised for those with hereditary risk factors.

When to Seek Professional Help

Seek medical attention if you experience blood in urine, persistent back pain, unexplained weight loss, or other concerning symptoms.

Tips for Medical Coders

• Use C64.2 for malignant neoplasms of the left kidney, excluding the renal pelvis. Ensure documentation specifies the left kidney and excludes the renal pelvis to support accurate coding.
