Today I claimed Carotid Artery Disease wherein my left Carotid Artery is 100% occlusion (Blocked) and it is listed in my VA records Problem Items and my recent Carotid Artery Disease Report recently in VA Notes of 27 July, 2017. It states in that report that I had Neck Radiotherapy due to Larynx Cancer. I have looked at the 38CFR4 and found Cardiovascular and the conditions underneath it, but can't find the disease in there. Does Anyone know what it falls under and what the code would be for rating it?
