The correct lipid panel and cholesterol screening codes depend on the patient’s status. For asymptomatic patients with no known lipid disorder, use Z13.220 (screening for lipoid disorders). For patients with established hyperlipidemia, use diagnosis codes like E78.0 (pure hypercholesterolemia), E78.1 (pure hypertriglyceridemia), E78.2 (mixed hyperlipidemia), or E78.5 (unspecified). Abnormal lipids without a formal diagnosis, use R79.89 as a bridge code. Do not use Z13.220 for patients with known hyperlipidemia. […]
