Chronic ischemic heart disease.Additional codes may be necessary to specify contributing factors.
Medical necessity for the diagnosis and management of chronic ischemic heart disease is established by the presence of symptoms, risk factors, and objective evidence of myocardial ischemia.This may involve diagnostic testing to assess the severity and extent of coronary artery disease and guide treatment decisions.The treatment plan should be medically appropriate and tailored to the individual patient's needs.
Diagnosis and management of chronic ischemic heart disease, including assessment of symptoms, risk factors, and response to treatment.This may involve various diagnostic tests (e.g., electrocardiogram, echocardiogram, cardiac catheterization) and therapeutic interventions (e.g., medication, lifestyle changes, coronary artery bypass grafting, angioplasty).
In simple words: Chronic ischemic heart disease means the heart muscle doesn't get enough blood over a long period due to narrowed arteries. This often happens because of hardened arteries.Doctors might use extra codes to explain other problems related to this condition.
Chronic ischemic heart disease (I25) refers to a long-standing reduction in blood flow to the heart muscle, leading to myocardial ischemia.This condition is typically caused by atherosclerosis (hardening of the arteries) narrowing the coronary arteries.The diagnosis necessitates considering the presence of angina pectoris and other associated conditions like chronic total occlusion of a coronary artery, tobacco use or exposure to environmental tobacco smoke.Additional codes should be used to specify other associated conditions such as hypertension, heart failure, or other contributing factors.
Example 1: A 65-year-old male patient presents with chest pain on exertion, shortness of breath, and history of smoking.Cardiac catheterization reveals significant coronary artery disease with stenosis.I25.10 (Chronic ischemic heart disease of native coronary artery without angina pectoris) is coded., A 72-year-old female patient with a history of hypertension and diabetes mellitus experiences recurrent episodes of angina.Coronary angiography shows multivessel disease with significant stenosis. I25.11 (Chronic ischemic heart disease of native coronary artery with angina pectoris) and I10 (Essential (primary) hypertension) are coded., An 80-year-old male patient with a history of myocardial infarction is admitted with worsening heart failure symptoms.Echocardiography reveals reduced ejection fraction and evidence of chronic ischemic cardiomyopathy.I25.5 (Chronic ischemic heart disease with heart failure) and I50.9 (Heart failure, unspecified) are coded.
Detailed patient history including symptoms (chest pain, shortness of breath, fatigue), risk factors (hypertension, diabetes, smoking, family history), results of physical examination, electrocardiogram, echocardiogram, coronary angiography, cardiac catheterization, and other relevant diagnostic tests.Treatment plan and response to treatment should also be documented.
** Chronic ischemic heart disease is a complex condition that can present with various symptoms and severity. Accurate coding requires detailed clinical documentation and careful consideration of all associated conditions and contributing factors.
