Clinical Information

• Ischemic Glomerulopathy-. a renal disorder characterized by glomerular damage due to ischemia. it leads to progressive deterioration of renal function.
• Congenital Nephrotic Syndrome-. a rare autosomal recessive inherited nephrotic syndrome that is present in the first week of life. it manifests with edema and proteinuria and usually has a poor prognosis.
• Congenital Nephrotic Syndrome - Cytomegalovirus Associated|Cytomegalovirus Associated Congenital Nephrotic Syndrome-. nephrotic syndrome associated with a cytomegalovirus infection, most commonly presenting in the first three months of life.
• Congenital Nephrotic Syndrome - Diffuse Mesangial Sclerosis|Diffuse Mesangial Sclerosis|Diffuse Mesangial Sclerosis-. nephrotic syndrome within the first three motnhs of life, characterized initially by increased mesangial matrix, with or without hypertrophy and hyperplasia of podocytes, and eventual glomerular sclerosis.
• Congenital Nephrotic Syndrome - Focal Segmental Glomerulosclerosis|Congenital FSGS|Congenital FSGS-. nephrotic syndrome within the first three months of life, characterized by scarring of the glomerulus, in which only part of the glomerulus is involved, and less than 50% of the glomeruli are affected.
• Congenital Nephrotic Syndrome - Infection Associated|Infection Associated Congenital Nephrotic Syndrome-. nephrotic syndrome presenting within the first three months of life, and which is associated with an infectious process.
• Congenital Nephrotic Syndrome - Rubivirus Associated|Rubivirus Associated Congenital Nephrotic Syndrome-. nephrotic syndrome associated with rubella, most commonly presenting in the first three months of life.
• Congenital Nephrotic Syndrome - Toxoplasma Associated|Toxoplasma Associated Congenital Nephrotic Syndrome-. nephrotic syndrome associated with toxoplasmosis, most commonly presenting in the first three months of life.
• Congenital Nephrotic Syndrome - Treponema Pallidum Associated|Treponema Pallidum Associated Congenital Nephrotic Syndrome-. nephrotic syndrome associated with syphilis, most commonly presenting in the first three months of life.
• Nephrotic Syndrome - NPHS1 Associated|Congenital Nephrotic Syndrome - Finnish Type-. nephrotic syndrome attributed to mutation(s) in the nphs1 gene, which encodes the protein nephrin, and most commonly presents during the first three months of life.
• Ischemic Nephropathy-. nephropathy due to hypoperfusion of the kidney.

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

Patient Education

Kidney Diseases

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes to your bladder, which stores the urine until you go to the bathroom.

Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You have a higher risk of kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. Chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include:

• Cancer
• Cysts
• Stones
• Infections

Your doctor can do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.
