Hypertensive heart disease code I11.0 is not a combination code, but it has an instructional note to indicate the type of heart failure. To use I11.0, the patient would have hypertensive heart disease with heart failure. (The instructional note is indicated below, which is in the tabular under I11.0 in the ICD-10 manual)
| Use additional code to identify type of heart failure (I50.-) (I50-I50.9) |
If the patient has hypertensive heart disease without heart failure or hypertensive heart disease NOS, , you would use I11.9.
Coronary artery disease (CAD) is I25.1xx which is a not the same as as hypertensive heart disease.
I hope this helps.
