I25.10
Atherosclerotic heart disease of native coronary artery without angina pectoris
I25.10 is a clinical classification for atherosclerotic heart disease (ASHD) involving the patient's original (native) coronary arteries in cases where the patient does not currently experience angina pectoris. This condition involves the narrowing or hardening of the arteries that supply blood to the heart muscle due to the buildup of plaque. In many clinical scenarios, this code represents stable coronary artery disease where symptoms are managed, subclinical, or absent despite documented arterial narrowing. It is the default code for coronary artery disease (CAD) or ASHD when no further specification of angina is provided in the documentation.
Clinical Symptoms
- Shortness of breath during exertion
- General fatigue
- Reduced exercise tolerance
- Palpitations
- Often asymptomatic (clinically silent)
Common Causes
- Hyperlipidemia and high LDL cholesterol
- Hypertension (High blood pressure)
- Chronic tobacco use or smoking history
- Diabetes mellitus
- Sedentary lifestyle and obesity
- Genetic predisposition and family history of early CAD
Documentation & Coding Tips
Use this code as the default for Coronary Artery Disease (CAD) or ASHD when the medical record does not mention angina pectoris.
Example: Documentation states 'Chronic CAD, stable on medical therapy' with no mention of chest pain.
Specify 'native' versus 'bypass graft' to ensure accurate coding; I25.10 is strictly for original vessels.
Example: Patient has CAD and a history of CABG; if the disease is in the graft, use a code from the I25.7- series instead.
If the patient has a history of a myocardial infarction, ensure the 'Old Myocardial Infarction' (I25.2) code is also considered if relevant to the encounter.
Example: Patient with stable CAD and an MI three years ago.
