Assessment of New Jersey’s Medicaid Prescription Drug Management Performance and Policy Options
The New Jersey Association of Health Plans enlisted the Menges Group to evaluate New Jersey’s Medicaid prescription drug costs and assess the potential impacts of a pharmacy carve-out approach, whereby the prescription drug benefit would be removed from the MCOs’ responsibility and paid for in the fee-for-service (FFS) setting. We also assess the impacts of two potential policy changes, including maintaining MCO responsibility for the prescription drug benefit but requiring the use of the same preferred drug list (PDL) and MCOs’ mandatory use of a single Pharmacy Benefits Manager (PBM) subcontractor.
We estimate that carving pharmacy benefits out of the MCO benefit package will cost the State of New Jersey $51 million in the first year, with cumulative state costs across the first five years of the carve-out totaling $454 million. Additionally, we find that due to a weakened ability to manage drug mix at the “front end,” moving to a uniform DHS-driven PDL will cost the State of New Jersey $3 million in the first year, with cumulative state costs across the first five years totaling $26 million. Finally, our analyses show that a policy approach of requiring all MCOs to use the same PBM is also unlikely to yield savings.
