Name of the Condition

• Chronic Nephritic Syndrome with C3 Glomerulonephritis

Summary

Chronic nephritic syndrome with C3 glomerulonephritis is a kidney disorder characterized by inflammation of the glomeruli, the filtering units of the kidneys. This subtype involves abnormal deposits of a protein component called C3 within the kidneys, affecting their ability to filter waste and excess fluid.

Causes

The exact cause of C3 glomerulonephritis is not well understood, but it is believed to be related to abnormal immune responses. It may involve an overactivation of the complement system, particularly affecting components like C3.

Risk Factors

• Genetic predispositions related to immune system regulation.
• Family history of kidney disease.
• Autoimmune diseases or conditions affecting immune system function.

Symptoms

• Hematuria (blood in urine)
• Proteinuria (excess protein in urine)
• Edema (swelling, particularly in the legs and ankles)
• Hypertension (high blood pressure)
• Reduced kidney function

Diagnosis

• Urinalysis (to detect blood and protein in urine)
• Blood tests (to assess kidney function and complement levels)
• Kidney biopsy (to examine kidney tissue and confirm C3 deposits)
• Imaging studies (like ultrasound to assess kidney structure)

Treatment Options

• Immunosuppressive medications (to reduce immune system activity)
• Antihypertensive drugs (to manage blood pressure)
• Diuretics (to help reduce fluid retention)
• Dietary modifications (such as reducing salt intake) These treatments aim to manage symptoms and prevent further kidney damage.

Prognosis and Follow-Up

The prognosis varies depending on the severity and response to treatment. Regular monitoring of kidney function and blood pressure is crucial. Long-term outcomes can include remission or progression to chronic kidney disease.

Complications

• Chronic kidney disease leading to potential kidney failure
• Increased risk of cardiovascular disease due to hypertension

Lifestyle & Prevention

• Adopting a low-sodium diet and reducing protein intake to lessen kidney strain.
• Regular exercise can help maintain overall health.
• Preventive measures include regular medical check-ups to monitor kidney health, especially for at-risk individuals.

When to Seek Professional Help

• Persistent or severe swelling in the extremities
• Noticeable blood in the urine
• New or worsening high blood pressure
• Unexplained fatigue or changes in urination patterns

Tips for Medical Coders

• Ensure accurate capture of the specific subtype by including the "C3 glomerulonephritis" detail inherent in the N03.A code.
• Verify accompanying conditions like hypertension or chronic kidney disease for additional coding.
• Avoid generic coding for nephritis and ensure specificity to reflect the chronic and C3-specific nature of the condition.
