The March 2018 edition of our 5 Slide Series tracks the national Medicaid market share and pre-rebate cost per prescription progression of curative Hepatitis C drugs from CY2014 through CY2017.

Additionally, we have quantified the considerable market share differences between MCO-paid and FFS-paid Medicaid prescriptions.
