Understanding IGA Glomerulonephritis: ICD-10 Codes And Diagnosis

What is IgA Glomerulonephritis ICD 10?

IgA Glomerulonephritis, also known as IgA Nephropathy, is a kidney disorder that occurs when the antibody IgA builds up in the kidneys, causing inflammation and damage to the glomeruli. The glomeruli are tiny filters in the kidneys that help remove waste and excess fluid from the blood. When the glomeruli become inflamed, they may not function properly, leading to symptoms such as blood and protein in the urine, swelling, and high blood pressure.

Clinical Information

IgA Glomerulonephritis is a common form of glomerulonephritis, accounting for about 25-30% of all cases of glomerulonephritis. It often presents with symptoms such as hematuria (blood in the urine), proteinuria (protein in the urine), and hypertension (high blood pressure). In some cases, it may progress to chronic kidney disease and end-stage renal disease.


The exact cause of IgA Glomerulonephritis is unknown, but it is believed to be an autoimmune disorder in which the immune system mistakenly attacks the kidneys. Genetic factors, infections, and environmental triggers may also play a role in the development of the condition.


Common symptoms of IgA Glomerulonephritis include blood in the urine (hematuria), protein in the urine (proteinuria), swelling in the hands and feet, high blood pressure, and fatigue. Some patients may also experience flank pain, frequent urination, and foamy urine.


Diagnosing IgA Glomerulonephritis typically involves a physical examination, blood tests, urine tests, imaging studies (such as ultrasound or CT scan), and a kidney biopsy. The presence of IgA deposits in the glomeruli on biopsy is a key diagnostic finding.


Treatment for IgA Glomerulonephritis aims to reduce inflammation, control symptoms, and slow the progression of kidney damage. This may include medications to reduce proteinuria and blood pressure, dietary changes, and in some cases, immunosuppressive therapy or dialysis.


IgA Glomerulonephritis is a complex kidney disorder that can have serious consequences if not properly managed. Early diagnosis and treatment are essential to prevent complications and preserve kidney function. By understanding the causes, symptoms, and treatment options for IgA Glomerulonephritis, patients and healthcare providers can work together to effectively manage the condition and improve outcomes.


1. Can IgA Glomerulonephritis be cured?

There is no cure for IgA Glomerulonephritis, but treatment can help manage symptoms and slow the progression of kidney damage.

2. Is IgA Glomerulonephritis a hereditary condition?

There is a genetic component to IgA Glomerulonephritis, but not everyone with a family history of the condition will develop it.

3. Are there any lifestyle changes that can help manage IgA Glomerulonephritis?

Following a healthy diet, maintaining a healthy weight, and avoiding smoking can help manage symptoms and improve kidney function in patients with IgA Glomerulone
