E78

E78 — Disorders of lipoprotein metabolism and other lipidemias

Non-billable headerICD-10-CM

E78 is a non-billable header ICD-10-CM code for disorders of lipoprotein metabolism and other lipidemias. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

sphingolipidosis (E75.0-E75.3)

Other codes that can never be billed with E78

These codes carry an Excludes1 note pointing at E78. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E78 alone.

L98.6Other infiltrative disorders of the skin and subcutaneous tissue
M14Arthropathies in other diseases classified elsewhere
M67Other disorders of synovium and tendon
Q87.1Congenital malformation syndromes predominantly associated with short stature
E78.2Mixed hyperlipidemia

Risk adjustment

E78 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead E78

10 child codes. Green means billable.
