Elevated Lipoprotein(a)

This code signifies an abnormally high level of Lipoprotein(a) [Lp(a)] in the blood. Elevated Lp(a) is an independent, genetically determined risk factor for atherosclerotic cardiovascular disease (ASCVD), including myocardial infarction and stroke, and calcific aortic valve disease.

Use this code when laboratory testing confirms an elevated Lp(a) level, typically above 30 mg/dL or 75 nmol/L, as documented by the ordering physician. This diagnosis is often made during cardiovascular risk assessment or investigation of premature ASCVD.

• Always ensure the medical record clearly documents the elevated Lp(a) level and the physician's interpretation of its significance.
• This code is often a secondary diagnosis, accompanying primary diagnoses related to ASCVD (e.g., I25.10, I63.9).
• Do not confuse with other dyslipidemias like hypercholesterolemia (E78.00, E78.01) unless those are also documented.
