List of ICD-10 Codes for Coronary Artery Disease
The primary code for coronary artery disease is I25. It is associated with chronic ischemic heart disease as a non-billable code. It cannot be converted to the ICD-9-CM version. There are nine categories of the I25 code ranging from I25.1 to I25.9. Let’s look at those categories in detail:
ICD 10 Code I25.1
This code is associated with atherosclerotic heart disease of a native coronary artery. It is also non-billable as it has subtypes with more details about the disease. Here is a closer look at those subtypes:
| ICD-10 Code | Disease-Associated | ICD-9-CM Code | Billable/Non-Billable |
|---|---|---|---|
| I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | 414.01 | Billable |
| I25.11 | Atherosclerotic heart disease of native coronary artery with angina pectoris | N/A | Non-Billable |
| I25.110 | Atherosclerotic heart disease of native coronary artery with unstable angina pectoris | 411.1 | Billable |
| I25.111 | Atherosclerotic heart disease of native coronary artery with documented spasm | 413.9 | Billable |
| I25.112 | Atherosclerotic heart disease of native coronary artery with refractory angina pectoris | N/A | Billable |
| I25.118 | Atherosclerotic heart disease of native coronary artery with other forms of angina pectoris | 413.9 | Billable |
| I25.119 | Atherosclerotic heart disease of native coronary artery with unspecified angina pectoris | 413.9 | Billable |
ICD 10 Code I25.2
This code is associated with old myocardial infarction. It is a billable code and the ICD-9-CM code for old myocardial infarction is 412.
ICD 10 Code I25.3
This code is associated with an aneurysm of the heart. It is also billable and the ICD-9-CM code for aneurysm of the heart is 414.10.
ICD 10 Code I25.4
This code is associated with a coronary artery aneurysm and dissection. Due to its two categories, you can neither bill it nor convert it to the ICD-9-CM version. We have explained those categories below:
| ICD-10 Code | Disease-Associated | Billable/Non-Billable | ICD-9-CM Code |
|---|---|---|---|
| I25.41 | Coronary artery aneurysm | Billable | 414.11 |
| I25.42 | Coronary artery dissection | Billable | 414.12 |
ICD 10 Code I25.5
This code is associated with ischemic cardiomyopathy. It is a billable code and the ICD-9-CM code for ischemic cardiomyopathy is 414.8.

You can apply this code to silent myocardial ischemia. This code is billable and the ICD-9-CM code for silent myocardial ischemia is 414.8.
