ICD-10 Code I25.83 – Coronary atherosclerosis due to lipid rich plaque (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.83 – Coronary atherosclerosis due to lipid rich plaque
What it is
This code identifies coronary artery disease caused by a lipid-rich plaque in the coronary vessels. Use it when the record specifies this plaque type as the reason for atherosclerotic coronary disease.
Clinical signs
Clinical features vary; refer to documentation. Patients may have evidence of coronary atherosclerosis on imaging, angiography, or pathology, with documentation of a lipid-rich plaque contributing to the lesion.
When to use this code
Use I25.83 when the provider documents coronary atherosclerosis due to lipid rich plaque, or an equivalent statement clearly linking the plaque type to the coronary disease. It may also apply when the diagnosis is confirmed in a report and stated as the cause of the coronary narrowing. Check documentation if the relationship is unclear.
Do not use for
Do not use this code for general coronary artery disease without documentation of a lipid-rich plaque. Do not assign it when the record only mentions atherosclerosis elsewhere or plaque type is unspecified.
Coding tip
Code the condition only when the lipid-rich plaque is explicitly documented as part of the coronary diagnosis.
