E78

E78 is an alphanumeric designation that appears in multiple, unrelated systems. In medical coding, E78 is the ICD-10-CM code category for disorders of lipoprotein metabolism and other lipids. This broad category encompasses a range of lipid disorders, with subcategories E78.0 through E78.9 providing more specific diagnoses. The code is used by clinicians and administrative staff to document, study, and bill for conditions such as hyperlipidemias and other dyslipidemias.

In the context of road transport, E78 is a European route in the international E-road network. The E-road network is a system of major cross-border highways designated by the United Nations Economic Commission for Europe (UNECE) to facilitate international travel and freight. The exact trajectory of route E78 spans multiple countries and is defined by national authorities in accordance with the E-road numbering scheme.

Because E78 can refer to different domains, its meaning depends on the surrounding field—healthcare administration versus transportation infrastructure. Related topics include ICD-10-CM coding and the European E-road network.
