272.4
ICD-9-CMThis code signifies elevated levels of lipids (fats) in the blood that do not fit into more specific categories of hyperlipidemia, such as pure hypercholesterolemia or pure hypertriglyceridemia. It often indicates a mixed dyslipidemia where multiple lipid fractions are abnormal, or when the specific type of lipid abnormality is not fully documented.
Use this code when documentation indicates hyperlipidemia without further specification of the primary elevated lipid component (e.g., "hyperlipidemia NOS," "mixed hyperlipidemia," or "elevated lipids"). It is appropriate when laboratory results show abnormal cholesterol and triglyceride levels, but a more precise diagnosis like familial hypercholesterolemia or hypertriglyceridemia is not provided.
