BillableAtherosclerotic heart disease of native coronary artery without angina pectoris
HCC Category Mapping
RxHCCHCC 188 — Coronary Artery Disease and Angina
0.000What This Code Means
Hardening and narrowing of the heart's blood vessels due to plaque buildup, without chest pain symptoms.
Coding Tips
- •This code indicates coronary artery disease without angina; confirm absence of anginal symptoms
- •Document the extent of atherosclerosis (native coronary artery involvement) in the medical record
Clinical Significance
Atherosclerotic heart disease of native coronary artery without angina is one of the most commonly coded cardiac diagnoses, representing coronary artery disease in patients who do not have anginal symptoms. While extremely prevalent, this code does NOT map to any HCC in V24 or V28 models, meaning it has no risk adjustment impact. It is important for clinical documentation but does not contribute to the patient's risk score.
Documentation Requirements
- ✓Provider documentation of coronary artery disease or atherosclerotic heart disease
- ✓Specification that native (non-grafted) coronary arteries are involved
- ✓Confirmation that the patient does not currently have angina pectoris
- ✓Supporting diagnostic evidence (cardiac catheterization, coronary computed tomography angiography, or stress test)
- ✓Current management plan (medications, lifestyle modifications)
