Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Diseases of arteries, arterioles and capillaries
      (I70-I79)
      • Atherosclerosis
        (I70)

I70 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of atherosclerosis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Atherosclerosis

Clinical Information

  • Atherosclerosis

    a thickening and loss of elasticity of the walls of arteries that occurs with formation of atherosclerotic plaques within the arterial intima.

  • Coronary Artery Disease

    pathological processes of coronary arteries that may derive from a congenital abnormality, atherosclerotic, or non-atherosclerotic cause.

  • Intracranial Arteriosclerosis

    vascular diseases characterized by thickening and hardening of the walls of arteries inside the skull. there are three subtypes: (1) atherosclerosis with fatty deposits in the arterial intima; (2) monckeberg's sclerosis with calcium deposits in the media and (3) arteriolosclerosis involving the small caliber arteries. clinical signs include headache; confusion; transient blindness (amaurosis fugax); speech impairment; and hemiparesis.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • arteriolosclerosis
  • arterial degeneration
  • arteriosclerosis
  • arteriosclerotic vascular disease
  • arteriovascular degeneration
  • atheroma
  • endarteritis deformans or obliterans
  • senile arteritis
  • senile endarteritis

Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
  • code to identify:
  • exposure to environmental tobacco smoke Z77.22
  • history of tobacco dependence Z87.891
  • occupational exposure to environmental tobacco smoke Z57.31
  • tobacco dependence F17
  • tobacco use Z72.0

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • arteriosclerotic cardiovascular disease I25.1
  • arteriosclerotic heart disease I25.1
  • atheroembolism I75
  • cerebral atherosclerosis I67.2
  • coronary atherosclerosis I25.1
  • mesenteric atherosclerosis K55.1
  • precerebral atherosclerosis I67.2
  • primary pulmonary atherosclerosis I27.0

Patient Education


Atherosclerosis

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.

Atherosclerosis 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 it until they have a medical emergency.

A physical exam, imaging, and other diagnostic tests can tell if you have it. Medicines can slow the progress of plaque buildup. Your doctor may also recommend procedures such as angioplasty to open the arteries, or surgery on the coronary or carotid arteries. Lifestyle changes can also help. These include following a healthy diet, getting regular exercise, maintaining a healthy weight, quitting smoking, and managing stress.
