  • I70 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2023 edition of ICD-10-CM I70 became effective on October 1, 2022.
  • This is the American ICD-10-CM version of I70 - other international versions of ICD-10 I70 may differ.

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

Clinical Information
  • A thickening and loss of elasticity of the walls of arteries that occurs with formation of atherosclerotic plaques within the arterial intima.
  • A vascular disorder characterized by thickening and hardening of the walls of the arteries.
  • Age, lifestyle, diet, and gene related degeneration of arteries due to deposition of lipoid plaques (atheromas) on inner arterial walls; main cause of coronary artery disease, a leading cause of death.
  • Atherosclerosis is a disease in which plaque builds up inside your arteries. Plaque is a sticky substance made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries. That limits the flow of oxygen-rich blood to your body and can lead to serious problems, including
    • coronary artery disease. These arteries supply blood to your heart. When they are blocked, you can suffer angina or a heart attack.
    • carotid artery disease. These arteries supply blood to your brain. When they are blocked you can suffer a stroke.
    • peripheral arterial disease. These arteries are in your arms, legs and pelvis. When they are blocked, you can suffer from numbness, pain and sometimes infections.
    atherosclerosis usually doesn't cause symptoms until it severely narrows or totally blocks an artery. Many people don't know they have the disease until they have a medical emergency.a physical examination, imaging and other diagnostic tests can tell if you have it. Treatments include medicines, and medical procedures or surgery. Lifestyle changes can also help. These include following a healthy diet, getting regular exercise, maintaining a healthy weight, quitting smoking, and managing stress.
  • Build-up of fatty material and calcium deposition in the arterial wall resulting in partial or complete occlusion of the arterial lumen.
  • Deposition of cholesterol and lipid in the inner layer of the blood vessel
  • The thickening of the wall of the small arteries and arterioles. It is caused by deposition of hyaline material in the wall or concentric smooth muscle wall hypertrophy. It results in lumen narrowing and tissue ischemia.
  • Thickening and loss of elasticity of arterial walls; atherosclerosis is the most common form of arteriosclerosis and involves lipid deposition and thickening of the intimal cell layers within arteries; additional forms of arteriosclerosis involve calcification of the media of muscular arteries (monkeberg medial calcific sclerosis) and thickening of the walls of small arteries or arterioles due to cell proliferation or hyaline deposition (arteriolosclerosis).
  • Thickening and loss of elasticity of the walls of arteries of all sizes. There are many forms classified by the types of lesions and arteries involved, such as atherosclerosis with fatty lesions in the arterial intima of medium and large muscular arteries.
  • Thickening of the walls of small arteries or arterioles due to cell proliferation or hyaline deposition.
