Angina Pectoris
November 3, 2020We are focusing on ICD-10 Category I20 – Angina Pectoris.
The codes in this category are:
|
ICD-10 Code |
Description |
|
120.0 |
Unstable angina |
|
120.1 |
Angina pectoris with documented spasm |
|
120.8 |
Other forms of angina pectoris |
|
120.9 |
Angina pectoris, unspecified |
When selecting a code from this category, the documentation should indicate:
- Type of angina
- Associated spasm (if applicable)
- Associated symptoms (if applicable)
According to the instructional notes, when coding angina equivalent, additional codes for associated symptoms should be added.
ICD-10 has combination codes that bundle atherosclerotic heart disease and angina. If the patient has both atherosclerotic coronary artery disease and angina, this should be reflected in the documentation and should be coded in one of these:
- Angina pectoris with atherosclerotic heart disease of native coronary arteries (I25.1-)
- Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris (I25.7-)
Category I20 also includes an instructional note to use an additional code to identify:
- Tobacco dependence (F17.-)
- Occupational exposure to environmental tobacco smoke (Z57.31)
- Tobacco use (Z72.0)
- Exposure to environmental tobacco smoke (Z77.22)
- History of tobacco dependence (Z87.891)
If the angina is following an acute MI/post-infarction, code I23.7 – post-infarction angina.
