CKD (Chronic Kidney Disease) ICD-10-CM Codes

What ICD-10 Codes Are Used for CKD?

Recognizing the correct CKD ICD codes is fundamental for accurate diagnosis and treatment. Here are some frequently used codes:

• N18.1: Chronic kidney disease (CKD) Stage 1: This code represents patients with slight kidney damage with normal or relatively high GFR.
• N18.2: Chronic kidney disease (CKD) Stage 2: Used for patients having a mildly reduced GFR with kidney damage.
• N18.3: Chronic kidney disease (CKD) Stage 3: This code applies to patients with a moderately reduced GFR.
• N18.4: Chronic kidney disease (CKD) Stage 4: This code is used for patients with severely reduced GFR.
• N18.5: Chronic kidney disease (CKD) Stage 5: Code for patients with very severe or end-stage renal disease.

Which CKD ICD Codes Are Billable?

Understanding which CKD ICD codes are billable can play a significant role in effective medical billing:

• N18.1: Yes, billable. Represents patients diagnosed with CKD Stage 1.
• N18.2: Yes, billable. Used when CKD Stage 2 is diagnosed.
• N18.3: Yes, billable. Applicable for patients with CKD Stage 3.
• N18.4: Yes, billable. Used when the patient is in CKD Stage 4.
• N18.5: Yes, billable. This code applies when the patient is CKD Stage 5 or end-stage renal disease.

Clinical Information

Chronic Kidney Disease (CKD) is a long-term condition where the kidneys do not work effectively:

• CKD is characterized by a gradual loss of kidney function over time.
• The disease is usually silent in the early stages and is often discovered accidentally during routine health checkups.
• Diabetes and high blood pressure are two primary causes of CKD.
• Typical symptoms (usually in advanced stages) include fatigue, swollen feet or hands, shortness of breath, and frequent urination.
• The primary goal of treatment is to prevent or slow down the progression of the disease and reduce complications.

Synonyms Include:

• Chronic renal disease
• Renal Insufficiency, chronic
• Chronic renal failure
• Kidney failure, chronic
