Navigating Stage 4 Kidney Disease: A Guide to Treatment and Medicare Coverage

When your kidney function drops to a glomerular filtration rate (GFR) between 15 and 29 mL/min, you have entered Stage 4 Chronic Kidney Disease (CKD). This is a serious stage where the kidneys are severely damaged, and waste products can begin to build up in your body, leading to noticeable symptoms and complications.

At this point, proactive management is everything. You'll work closely with a nephrologist to slow the disease's progression and make critical decisions about your future care, such as preparing for dialysis or a kidney transplant. Getting timely access to specialists is key, and an advocate can help you get an earlier nephrologist appointment to start this process sooner.

Symptoms and Complications of Stage 4 CKD

As your kidneys lose their ability to filter waste and fluids, symptoms often become more apparent.

• Fatigue and weakness, often caused by anemia.
• Swelling (edema) in the legs, ankles, or hands due to fluid retention.
• Shortness of breath, from fluid in the lungs or anemia.
• Nausea, poor appetite, and unintended weight loss.
• Itchy skin (pruritus) from the buildup of waste products.
• Muscle cramps, especially at night.
• Difficulty sleeping and concentrating ("brain fog").

According to the CDC, more than one in seven U.S. adults are estimated to have CKD, yet a staggering nine out of ten are unaware they have it. Because the early stages are often silent, many people don't receive a diagnosis until the damage is severe. This is why regular screening and early detection are so important for slowing disease progression.

Treatment and Management Options

The goal of treatment in Stage 4 is to preserve your remaining kidney function, manage symptoms, and prepare for the future.

Medications and Medical Care

Your nephrologist will likely prescribe several medications to manage complications:

• ACE inhibitors or ARBs to control high blood pressure.
• SGLT2 inhibitors to help slow the progression of kidney damage.
• Phosphate binders to protect your bones.
• Erythropoiesis-stimulating agents (ESAs) to treat anemia.
• Diuretics to manage fluid retention and swelling.

Preparing for Dialysis

While not always immediately necessary in Stage 4, planning for dialysis early can lead to better outcomes and prevent emergencies. Your care team will educate you on the types of dialysis:

• Hemodialysis: Uses a machine to filter your blood, typically at a center.
• Peritoneal dialysis: Uses the lining of your abdomen as a filter, often done at home. An advocate can be crucial in this phase, especially when facing insurance hurdles like getting a dialysis prior authorization appeal approved.

Evaluating for a Kidney Transplant

You can be referred to a transplant center and begin the evaluation process even before you need dialysis. Overcoming transplant referral barriers early is key. Options include a living donor transplant or a deceased donor transplant.

Lifestyle and Dietary Changes

Working with a renal dietitian is essential. A kidney-friendly diet typically involves:

• Limiting sodium, potassium, and phosphorus.
• Controlling your protein intake.
• Monitoring fluid intake.
• Strictly managing blood pressure and blood sugar.
• Avoiding NSAIDs (like ibuprofen), which can harm the kidneys.
