Elevated Lipoprotein(a)

Code E78.41, Elevated lipoprotein(a), was created for elevated Lipoprotein(a) (also represented as Lp(a), a common genetic lipid disorder that increases the risk for early cardiovascular disease including myocardial infarction, stroke, peripheral artery disease and calcific aortic valve stenosis. Lipoprotein(a) is a plasma lipoprotein that is similar to LDL (low-density lipoprotein) in containing one molecule of apolipoprotein B (apoB), but differs in that it contains the additional protein, apolipoprotein(a) (apo(a)).
