Coronary atherosclerosis due to lipid rich plaque

This code describes coronary artery disease specifically attributed to the presence of lipid-rich plaque within the coronary arteries. This type of plaque is characterized by a high lipid content, often associated with a higher risk of rupture and subsequent acute coronary events. It represents a specific pathological characteristic of atherosclerosis affecting the heart's blood supply.

Use this code when documentation explicitly states coronary atherosclerosis due to lipid-rich plaque, or when imaging studies (e.g., intravascular ultrasound, optical coherence tomography) confirm the presence of lipid-rich plaque in the coronary arteries. This diagnosis is typically made in patients undergoing cardiac catheterization or other advanced imaging for suspected or known coronary artery disease.

• Ensure documentation clearly specifies "lipid-rich plaque" as the cause of the coronary atherosclerosis, not just general atherosclerosis.
• Do not use this code for general coronary atherosclerosis without specific mention of lipid-rich plaque.
• Consider sequencing this code as a secondary diagnosis if an acute coronary syndrome is also present, as the lipid-rich plaque may be the underlying cause.
