unstable angina icd 9

How do I find the ICD-9 code for this diagnosis?

I am taking a class, and I have run out of ideas regarding where to find the following description in the alphabetical index of a practice exercise.
Total occlusion of two bypass grafts with unstable angina
(and I am assuming that the “total occlusion” part is the first-listed diagnosis)

I have found occlusion, and as far as I can tell, there is nothing about grafts in that section. I cannot locate it elsewhere either. Obviously, I’m doing something wrong.
I don’t want the actual code; just directions on where to find it.

YOu go into diseases of the circulatory system, then into ischemic heart disease. Occlusion of the grafts are grafts in the heart after coronary bypass surgery, they now have a clot causing angina (unstable-which is the primary diagnosis). Code 414. which fits some of this, but that section has others as well.
