In a memorandum to Medicare Advantage Organizations, the Centers for Medicare & Medicaid Services today announced new flexibility related to the use of step therapy in coverage of Part B services. The agency will allow MA plans to impose step therapy requirements for covered Part B drugs beginning in the 2019 plan year. In addition, the agency will permit those plans that also provide Part D coverage to require that a beneficiary try a Part D drug therapy prior to covering a Part B drug therapy. Federal law allows plans to use some utilization management tools, such as prior authorization; however, the agency has previously not allowed the use of step therapy, nor plans to manage coverage across the Part B and D benefits. The agency will require any plans that take advantage of this new flexibility to provide notice to beneficiaries, as well as additional care coordination services to support access to care.
