Official Coding Guidelines

I13 combo codes; add I50 for type of heart failure

The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include hypertension, heart disease and chronic kidney disease. Assign codes from combination category I13, Hypertensive heart and chronic kidney disease, when there is hypertension with both heart and chronic kidney disease. If heart failure is present, assign an additional code from category I50 to identify the type of heart failure.

Use N18 with I13 to identify CKD stage

The appropriate code from category N18, Chronic kidney disease, should be used as a secondary code with a code from category I13 to identify the stage of chronic kidney disease.
