Thanks but that is not what I am looking for. I have a picture of the heart with the 5 major arteries and the branches coming off the arteries but someone colored over the chart with the branch names so when a doctor states is talking about RPL 1, 2 or 3 I can not see where that is located on my key. I am just trying to get a clean picture That I can read which artery a particular branch is connecting to.Have you tried looking at the illustrations in the back of your ICD-10-CM book? I find the cardiac ones very helpful.
