Chronic Kidney Disease ICD-10-CM Codes

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
