About the I70–I79 Code Range
These conditions affect arteries, arterioles and capillaries. Atherosclerosis means artery walls thicken and lose elasticity as plaques form inside them.
I70 separates atherosclerosis by artery or, for limb bypass grafts, by graft type. I71 covers aortic aneurysms and dissections, with aneurysms divided by site and rupture status. I72 sorts other aneurysms by artery. I73 groups other peripheral vascular diseases, including Raynaud's syndrome and Buerger's disease.
I74 sorts arterial embolism and thrombosis by affected artery. I75 separates atheroembolism by site; it involves cholesterol-rich deposits blocking a blood vessel. I76 identifies septic arterial embolism. I77 groups other artery and arteriole disorders, while I78 concerns capillaries. I79 identifies vessel disorders in diseases classified elsewhere, distinguishing aortic aneurysm, aortitis and other disorders.
