What ICD-10 Codes Are Used for Chronic Kidney Disease?
The correct Chronic Kidney Disease ICD codes is essential for accurate diagnosis and treatment. Here are the most commonly used codes:
- N18.1: Chronic kidney disease (CKD), Stage 1: This code is used for the early stages of CKD, where damage is minimal, and the kidneys are still capable of functioning normally.
- N18.2: Chronic kidney disease, Stage 2 (mild): This code denotes CKD in its second stage, characterized by mild kidney damage and slightly lowered kidney function.
- N18.3: Chronic kidney disease, Stage 3 (moderate): This code signifies moderate kidney damage and reduced kidney function, marking the third stage of CKD.
- N18.4: Chronic kidney disease, Stage 4 (severe): This code applies to severe kidney damage with significantly decreased kidney function, a sign of advanced CKD.
- N18.5: Chronic kidney disease, Stage 5: This code is used for the final stage of CKD, where the kidneys have almost or entirely lost their ability to function.
Which Chronic Kidney Disease ICD Codes Are Billable?
Determining which codes are billable is crucial for correct medical billing:
- N18.1: Yes, billable. This code signifies early-stage CKD, where kidney function remains essentially normal.
- N18.2: Yes, billable. It applies to CKD stage 2, characterized by slight kidney damage and mildly lowered function.
- N18.3: Yes, billable. It denotes CKD stage 3, characterized by moderate kidney damage and reduced function.
- N18.4: Yes, billable. This code is for CKD stage 4, indicating severe kidney damage with significantly decreased function.
- N18.5: Yes, billable. It's used for CKD stage 5, representing a severe or total loss of kidney function.
Clinical Information
Chronic kidney disease (CKD) is a long-term condition where the kidneys do not function as well as they should. This condition has several stages, progressing from minor damage to complete kidney failure:
- Chronic kidney disease is a progressive disorder characterized by gradually losing kidney function.
- It is often diagnosed through blood and urine tests that detect early signs of kidney damage.
- High blood pressure and diabetes are the most common causes of CKD.
- Common symptoms of CKD include fatigue, trouble sleeping, and frequent urination.
- CKD may lead to complications like heart disease, weakened bones, anemia, and nerve damage.
- CKD is not curable, but its progression can be slowed with appropriate treatment, which often includes medication, diet changes, and, in the later stages, dialysis or a kidney transplant.
Synonyms Include:
- Chronic renal disease
- CKD
- Chronic renal failure
- Chronic renal insufficiency

Commonly asked questions
Chronic kidney disease is often caused by high blood pressure and diabetes, which damage the kidneys over time.
CKD is not curable, but its progression can be slowed with appropriate treatment, including medication, diet changes, and in later stages, dialysis or a kidney transplant.
Symptoms can include fatigue, trouble sleeping, and frequent urination. However, early stages of CKD may not present noticeable symptoms.
