Pure hypercholesterolemia, unspecified

This code signifies an elevated level of total cholesterol and/or LDL cholesterol in the blood, without further specification of the type of hyperlipidemia. It indicates a primary dyslipidemia where other lipid fractions (triglycerides, HDL) are not explicitly abnormal or are not the primary focus of the diagnosis. This condition increases the risk of cardiovascular disease.

Use this code when documentation clearly states "pure hypercholesterolemia" or "hypercholesterolemia, unspecified," and there is no further information regarding specific lipoprotein abnormalities (e.g., hypertriglyceridemia, mixed hyperlipidemia). This code is appropriate when a provider identifies elevated cholesterol but does not specify the underlying genetic or acquired cause, or the specific lipoprotein fraction involved beyond general cholesterol elevation.

• Avoid using this code if documentation specifies other lipid abnormalities, such as hypertriglyceridemia (E78.1) or mixed hyperlipidemia (E78.2).
• Always seek clarification from the provider if the documentation is vague regarding the specific type of hyperlipidemia.
• This code is often used when initial lab results show elevated cholesterol, and further diagnostic workup is pending or not yet performed.
