.png)
Hyperlipidemia is a lipid metabolism disorder characterized by abnormally elevated levels of cholesterol, triglycerides, or both in the bloodstream. Clinically, it represents a major risk factor for cardiovascular diseases such as coronary artery disease, myocardial infarction, stroke, and atherosclerosis. Because hyperlipidemia is frequently asymptomatic, accurate diagnosis and documentation depend primarily on laboratory findings rather than clinical presentation alone. In medical coding, hyperlipidemia is classified under ICD-10-CM category E78 (Disorders of lipoprotein metabolism and other lipidemias) . This category includes multiple diagnosis codes that reflect specific lipid abnormalities, including E78.0 (pure hypercholesterolemia), E78.1 (pure hypertriglyceridemia), E78.2 (mixed hyperlipidemia), and E78.01 (familial hypercholesterolemia) . When clinical documentation lacks specificity, E78.5 (hyperlipidemia, unspecified) is commonly assigned, although it...
