Coronary Artery Disease ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Coronary Artery Disease?

Coronary Artery Disease (CAD) is a prevalent cardiovascular condition characterized by the narrowing or blockage of coronary arteries that supply blood to the heart muscle. Accurate coding of CAD is essential for effective medical documentation and billing purposes. Here are several commonly used ICD-10 codes for Coronary Artery Disease, along with their clinical descriptions:

I25.10 - Atherosclerotic heart disease of native coronary artery without angina pectoris

This code indicates the presence of atherosclerosis in the coronary arteries without associated angina pectoris.

I25.110 - Atherosclerotic heart disease of native coronary artery with unstable angina pectoris

This code signifies the presence of unstable angina, which is chest pain or discomfort caused by reduced blood flow to the heart due to atherosclerosis in the coronary arteries.

I25.2 - Old myocardial infarction

This code is used when a patient has previously experienced a myocardial infarction (heart attack) and is now stable.

I25.5 - Ischemic cardiomyopathy

Ischemic cardiomyopathy is a condition where the heart's ability to pump blood is weakened due to insufficient blood supply caused by coronary artery disease. This code indicates the presence of this condition.

I25.6 - Silent myocardial ischemia

Silent myocardial ischemia refers to the lack of noticeable symptoms of reduced blood flow to the heart. This code is assigned when there is evidence of such ischemia without apparent symptoms.

I25.700 - Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart without angina pectoris

This code indicates the presence of atherosclerosis in the bypass graft or transplanted coronary artery without associated angina pectoris.

I25.710 - Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with unstable angina pectoris

This code is used when there is atherosclerosis in the bypass graft, transplanted coronary artery, and unstable angina pectoris.

I25.810 - Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris

This code signifies the presence of atherosclerosis in the bypass graft or transplanted coronary artery along with angina pectoris.

I25.9 - Chronic ischemic heart disease, unspecified

This code is assigned when chronic ischemic heart disease (reduced blood flow to the heart) cannot be further specified or adequately described.

I25.89 - Other forms of chronic ischemic heart disease

This code is used for chronic ischemic heart disease that does not fit the abovementioned categories.

Accurate coding of Coronary Artery Disease is crucial for proper healthcare management, reimbursement, and statistical analysis. It is important to consult the current ICD-10-CM guidelines and documentation provided by the American Medical Association (AMA) for comprehensive and up-to-date information on coding practices.

Which Coronary Artery Disease ICD codes are Billable?

I25.10 - Atherosclerotic heart disease of native coronary artery without angina pectoris:

Yes, this code is billable as it represents the presence of atherosclerosis in the coronary arteries without associated angina pectoris, requiring medical attention and treatment.

I25.110 - Atherosclerotic heart disease of a native coronary artery with unstable angina pectoris:

Yes, this code is billable as it indicates unstable angina, a serious condition requiring immediate medical intervention.

I25.2 - Old myocardial infarction:

Yes, this code is billable as it signifies a previous heart attack that may necessitate ongoing management and follow-up care.

I25.5 - Ischemic cardiomyopathy:

Yes, this code is billable as it represents a specific form of heart muscle damage resulting from reduced blood supply due to coronary artery disease, requiring ongoing monitoring and treatment.

I25.6 - Silent myocardial ischemia:

Yes, this code is billable as it indicates myocardial ischemia (reduced blood flow to the heart) without noticeable symptoms, which requires medical attention and appropriate management.

I25.700 - Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart without angina pectoris:

Yes, this code is billable as it represents the presence of atherosclerosis in bypass grafts or transplanted coronary arteries without angina pectoris, requiring medical evaluation and potential intervention.

I25.710 - Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with unstable angina pectoris:

Yes, this code is billable as it signifies the presence of atherosclerosis in bypass grafts or transplanted coronary arteries with unstable angina, necessitating immediate medical attention, and potential intervention.

I25.810 - Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris:

Yes, this code is billable as it represents the presence of atherosclerosis in bypass grafts or transplanted coronary arteries with angina pectoris, requiring medical evaluation and potential treatment.

I25.9 - Chronic ischemic heart disease, unspecified:

Yes, this code is billable as it encompasses chronic ischemic heart disease that cannot be further specified, indicating the need for ongoing management and treatment.

I25.89 - Other forms of chronic ischemic heart disease:

Yes, this code is billable as it covers other specific forms of chronic ischemic heart disease not classified elsewhere, requiring appropriate medical attention and treatment.

Clinical Information

• Coronary Artery Disease (CAD) is a common cardiovascular condition characterized by the narrowing or blockage of coronary arteries, restricting blood flow to the heart muscle.
• The primary cause of CAD is atherosclerosis, a buildup of plaque consisting of cholesterol, fatty deposits, and other substances on the arterial walls.
• CAD often presents with symptoms such as chest pain or discomfort (angina), shortness of breath, fatigue, and in some cases, no symptoms at all (silent myocardial ischemia).
• CAD risk factors include age, family history, high blood pressure, high cholesterol levels, smoking, obesity, diabetes, and a sedentary lifestyle.
• Diagnosis of CAD involves a combination of patient history, physical examination, diagnostic tests (such as electrocardiogram, stress tests, cardiac catheterization), and imaging techniques (such as coronary angiography, CT scan, or MRI).
• Management of CAD focuses on lifestyle modifications (such as adopting a heart-healthy diet, regular exercise, and smoking cessation), medication therapies (including statins, antiplatelet agents, beta-blockers), and, in severe cases, invasive procedures like angioplasty or coronary artery bypass grafting (CABG).
• Complications of CAD may include heart attack (myocardial infarction), arrhythmias, heart failure, and even sudden cardiac death.
• Ongoing monitoring, regular check-ups, and adherence to prescribed medications and lifestyle changes are crucial in managing CAD and reducing the risk of complications.
• Patient education and awareness about CAD, its symptoms, and the importance of early detection and management play a significant role in preventing disease progression and improving outcomes.
• Collaborative care involving cardiologists, primary care physicians, dietitians, and other healthcare professionals ensures comprehensive management of CAD and supports patients in leading heart-healthy life.
