Name of the Condition

• Recurrent and Persistent Hematuria with C3 Glomerulonephritis (ICD Code N02.A)

Summary

• This condition involves the repeated presence of blood in the urine along with a specific kidney disease called C3 glomerulonephritis. C3 glomerulonephritis is characterized by the abnormal activation of the complement system, leading to kidney damage.

Causes

• The exact cause of C3 glomerulonephritis is not completely understood but is believed to involve abnormalities in the complement system. Genetic mutations and infections can also contribute to its development.

Risk Factors

• Genetic predisposition, family history of kidney diseases, and history of autoimmune diseases can increase the risk of developing C3 glomerulonephritis.

Symptoms

• Symptoms include dark or blood-tinged urine, swelling in the legs or abdomen, high blood pressure, and fatigue due to kidney impairment.

Diagnosis

• Diagnosis typically involves a combination of urine tests to detect hematuria, blood tests to assess kidney function, and a kidney biopsy to confirm C3 glomerulonephritis.

Treatment Options

• Treatment may include medications to control blood pressure and reduce proteinuria, immunosuppressive therapy to manage the immune response, and, in severe cases, dialysis or kidney transplant. The aim is to slow disease progression and manage symptoms.

Prognosis and Follow-Up

• The prognosis varies; early diagnosis and treatment can improve outcomes. Regular follow-up with a healthcare provider is essential for monitoring kidney function and adjusting treatment as necessary.

Complications

• If left untreated, the condition can lead to chronic kidney disease, end-stage renal disease, or other cardiovascular complications due to persistent high blood pressure.

Lifestyle & Prevention

• Adopting a kidney-friendly diet, managing blood pressure, and avoiding nephrotoxic substances can help manage the condition. There are currently no specific preventive measures due to the condition's genetic nature.

When to Seek Professional Help

• Immediate medical attention is needed if there are symptoms of worsening kidney function, such as reduced urine output, significant swelling, or severe high blood pressure.

Tips for Medical Coders

• Verify the diagnosis through biopsy reports and urine tests to ensure accurate coding.
• Be aware of similar conditions that may cause hematuria and require different ICD codes to avoid misclassification.
