 | Coding 

We have a couple of questions regarding the coding of hyperlipidemia with hypercholesterolemia.



If a provider has documented mixed hyperlipidemia and hypercholesterolemia in the record, do you code both conditions?


Only assign code E78.2 for mixed hyperlipidemia.  Pure hypercholesterolemia, unspecified (E78.00) is included with code E78.2 so it is not coded separately. 

Effective date:  June 9, 2023



How do you code unspecified hyperlipidemia and hypercholesterolemia?


In this case, only the code for pure hypercholesterolemia, unspecified (E78.00) is assigned.  Hyperlipidemia, unspecified (E78.5) is not coded separately since hypercholesterolemia identifies the specific blood lipid elevated.

Effective date:  June 3, 2022


Hypercholesterolemia is defined as a high blood cholesterol level.

Hyperlipidemia is defined as high lipid or fat levels in the blood.
