Understanding Non-Obstructive Coronary Artery Disease NOCAD diagnosis documentation and medical coding is crucial for accurate healthcare reimbursement. This resource provides information on INOCA symptoms diagnosis treatment and management including angina microvascular dysfunction and coronary vasospasm. Learn about appropriate ICD-10 codes like I25.110 and CPT codes for cardiac catheterization nuclear stress testing and other diagnostic procedures related to NOCAD. Improve your clinical documentation for optimal reimbursement and patient care with comprehensive guidance on Non-Obstructive Coronary Artery Disease.
Also known as
Atherosclerotic heart disease
Coronary artery disease due to plaque buildup.
Angina pectoris
Chest pain due to reduced blood flow to the heart.
Other forms of chronic ischemic heart disease
Includes chronic stable angina and silent ischemia.

Coding I25.9 without further specification when documentation supports a more specific non-obstructive CAD subtype leads to inaccurate risk adjustment.
Incorrectly coding atherosclerosis (I25.1) as the primary diagnosis when non-obstructive CAD (I25.8x) is the principal finding impacts severity reflection.
Lack of clear clinical indicators for non-obstructive CAD in the documentation makes accurate code assignment (I25.8x) challenging, leading to potential audits.
Patient presents with symptoms suggestive of non-obstructive coronary artery disease (NOCAD). The patient reports experiencing angina, chest pain, or chest discomfort, particularly with exertion. Associated symptoms may include shortness of breath (dyspnea), fatigue, and palpitations. Physical examination may reveal normal cardiac auscultation. The patient's medical history includes risk factors for coronary artery disease such as hypertension, hyperlipidemia, diabetes mellitus, smoking, family history of CAD, or obesity. Diagnostic workup for NOCAD may include a coronary angiogram demonstrating no significant obstructive coronary artery disease (less than 50% stenosis), cardiac stress testing showing evidence of ischemia, or cardiac MRI revealing abnormalities in myocardial perfusion. The patient's current medications may include antianginal medications such as nitrates or beta-blockers, statins for cholesterol management, and antiplatelet therapy such as aspirin. The treatment plan includes optimizing medical therapy for risk factor modification, focusing on lifestyle changes including diet, exercise, and smoking cessation. Further evaluation may include assessment of microvascular angina or vasospastic angina as potential underlying mechanisms. Patient education regarding symptom management and medication adherence was provided. Follow-up appointment scheduled to monitor symptom control and treatment efficacy.
