On January 19, 2016, the Office of Management and Budget once again released the Medicaid Covered Outpatient Drugs Final Rule (commonly referred to as the Final AMP Rule) back to the Centers for Medicare & Medicaid Services (CMS). The precise time of the public release by CMS is anyone guess but it is expected to be imminent. As we previously noted in another blog, it has been almost 4 years since publication of the 2012 Proposed AMP Rule aimed at implementing changes to the AMP calculation as set forth in the Affordable Care Act.
