The ICD-10 code for chronic kidney disease (CKD) is assigned based on the specific stage of the disease and any associated complications. The main category for CKD is “N18,” and it has subcategories to indicate the stage of CKD. Here are the ICD-10 codes for different stages of CKD:
- N18.1 – Chronic kidney disease, stage 1:
- Kidney damage with normal or increased glomerular filtration rate (GFR) ≥ 90 mL/min/1.73 m².
- N18.2 – Chronic kidney disease, stage 2:
- Kidney damage with mild decrease in GFR (60-89 mL/min/1.73 m²).
- N18.3 – Chronic kidney disease, stage 3:
- Moderate decrease in GFR (30-59 mL/min/1.73 m²).
- N18.4 – Chronic kidney disease, stage 4:
- Severe decrease in GFR (15-29 mL/min/1.73 m²).
- N18.5 – Chronic kidney disease, stage 5:
- Kidney failure (GFR < 15 mL/min/1.73 m²) or requiring dialysis.
- N18.6 – End-stage renal disease:
- This code is used when the patient requires dialysis or has received a kidney transplant.
These codes are used to classify the stage of chronic kidney disease based on the glomerular filtration rate (GFR) and the level of kidney function. Additionally, there are codes for complications associated with CKD, such as hypertension, anemia, and electrolyte imbalances.
It’s important to accurately code the patient’s condition to ensure proper medical record-keeping, billing, and data analysis. The specific code used will depend on the patient’s clinical situation and medical history. Healthcare providers and medical coders are trained to select the appropriate ICD-10 code based on the patient’s individual circumstances.
Assignment of Chronic kidney disease (CKD)
The assignment of the ICD-10 code for chronic kidney disease (CKD) is based on several factors, including the stage of the disease, the presence of any associated complications or manifestations, and the healthcare provider’s clinical assessment and documentation. The coding process involves accurately translating the patient’s medical condition and information into a standardized code that represents their diagnosis. Here’s how the ICD-10 code for CKD is determined:
- Clinical Evaluation: The healthcare provider evaluates the patient’s medical history, physical examination findings, laboratory results (including glomerular filtration rate or GFR), imaging studies, and other relevant information.
- Disease Stage: CKD is categorized into stages based on the severity of kidney damage and the level of kidney function. The specific ICD-10 code is selected to correspond with the appropriate stage of CKD:
- N18.1: CKD Stage 1
- N18.2: CKD Stage 2
- N18.3: CKD Stage 3
- N18.4: CKD Stage 4
- N18.5: CKD Stage 5
- N18.6: End-stage renal disease
- Complications and Manifestations: If the patient has any associated complications or manifestations of CKD, additional codes may be added to reflect those conditions. These could include codes for hypertension, anemia, electrolyte imbalances, or other related conditions.
- Documentation: Accurate and thorough documentation by the healthcare provider is crucial. Clear and specific documentation ensures that the correct ICD-10 code is assigned. The documentation should include details about the CKD stage, any complications, and other relevant clinical information.
- Coding Expertise: Medical coders or healthcare professionals responsible for coding are trained to translate the clinical information into the appropriate ICD-10 code. They use their knowledge of the ICD-10 coding guidelines and conventions to ensure accuracy.
- Regulatory and Billing Compliance: The assigned ICD-10 code plays a significant role in medical record-keeping, billing, insurance claims, and data analysis. Proper coding ensures that healthcare institutions comply with regulatory requirements and accurately represent the patient’s condition.
It’s important to note that accurate coding requires collaboration between healthcare providers, medical coders, and billing personnel. The ICD-10 code serves as a standardized way to communicate the patient’s diagnosis, ensuring continuity of care and accurate reporting across the healthcare system.
