Molecular and Genomic Testing Program

Horizon collaborates with eviCore healthcare (eviCore) to conduct pre- and post-service Medical Necessity Determination (MND) reviews of certain molecular and genomic diagnostic testing services that are rendered in a physician’s office or clinical laboratory setting.

This program applies to Horizon members in fully-insured products and Administrative Services Only (ASO) accounts that participate in the Molecular and Genomic Testing Program.
