I13.10

HCC Category Mapping

What This Code Means

High blood pressure that has damaged both the heart and kidneys, with kidney disease in stages 1-4, but without heart failure.

Coding Tips

• •I13.10 requires documentation of hypertension and CKD stages 1-4 without heart failure; verify absence of heart failure documentation
• •This code represents hypertensive heart and kidney disease without the complication of heart failure

Clinical Significance

This combination code captures hypertensive heart disease and chronic kidney disease (stages 1-4 or unspecified) WITHOUT heart failure. It represents a common clinical scenario where hypertension has caused or coexists with both cardiac structural changes and kidney disease, but heart failure has not yet developed. Monitoring for progression to heart failure is clinically important.

Documentation Requirements

• ✓Documented diagnosis of hypertension
• ✓Documented heart disease (e.g., left ventricular hypertrophy, cardiomegaly) without heart failure
• ✓Documented chronic kidney disease with stage specified (1-4 or unspecified)
• ✓Additional code from N18.1-N18.4 or N18.9 required for CKD stage
• ✓Explicit confirmation that heart failure is NOT present
• ✓Current eGFR for CKD staging
• ✓Current treatment regimen for both conditions
• ✓Cardiac imaging results when available (echocardiogram showing structural changes)
