ICD-10-CM Code I25.81

Atherosclerosis of other coronary vessels without angina pectoris

Version 2021 Non-Billable Code

Not Valid for Submission

I25.81 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of atherosclerosis of other coronary vessels without angina pectoris. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

ICD-10:I25.81
Short Description:Atherosclerosis of oth coronary vessels w/o angina pectoris
Long Description:Atherosclerosis of other coronary vessels without angina pectoris

Consider the following ICD-10 codes with a higher level of specificity:

  • I25.810 - Atherosclerosis of coronary artery bypass graft(s) without angina pectoris
  • I25.811 - Atherosclerosis of native coronary artery of transplanted heart without angina pectoris
  • I25.812 - Atherosclerosis of bypass graft of coronary artery of transplanted heart without angina pectoris

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I25.81:

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, if applicable, to identify:
  • coronary atherosclerosis due to calcified coronary lesion I25.84
  • coronary atherosclerosis due to lipid rich plaque I25.83

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.
  • atherosclerotic heart disease of native coronary artery without angina pectoris I25.10

Code Classification

  • Diseases of the circulatory system (I00–I99)
    • Ischemic heart diseases (I20-I25)
      • Chronic ischemic heart disease (I25)

Code History

  • FY 2016 - New Code, effective from 10/1/2015 through 9/30/2016
    (First year ICD-10-CM implemented into the HIPAA code set)

Information for Patients


Atherosclerosis

Also called: Arteriosclerosis

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.

Coronary Artery Disease

Also called: CAD, Coronary arteriosclerosis, Coronary atherosclerosis

Coronary artery disease (CAD) is the most common type of heart disease. It is the leading cause of death in the United States in both men and women.

CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls. This buildup is called atherosclerosis. As it grows, less blood can flow through the arteries. As a result, the heart muscle can't get the blood or oxygen it needs. This can lead to chest pain (angina) or a heart attack. Most heart attacks happen when a blood clot suddenly cuts off the hearts' blood supply, causing permanent heart damage.

Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias. Heart failure means the heart can't pump blood well to the rest of the body. Arrhythmias are changes in the normal beating rhythm of the heart.
