HCC Category Mapping

What This Code Means

High blood pressure that has damaged both the heart and kidneys, with the heart failing to pump effectively and kidney disease in stages 1-4.

Coding Tips

• •I13.0 requires documentation of hypertension, heart failure, AND chronic kidney disease stages 1-4; all three conditions must be present
• •Do not use I13.0 if stage 5 CKD is present; use I13.11 or I13.2 depending on heart failure status

Clinical Significance

This combination code captures the triad of hypertension, heart failure, and chronic kidney disease (stages 1-4 or unspecified), representing a complex clinical scenario with significant morbidity. Per ICD-10-CM guidelines, when hypertension coexists with both heart failure and CKD, a causal relationship is assumed. This code requires additional codes for both the heart failure type and CKD stage.
