Justice in Aging submitted extensive comments to the draft 2016 Call Letter for Medicare Part C and Part D plans to the Centers for Medicare and Medicaid Services (CMS). CMS issues the Call Letter annually to highlight areas where it is changing requirements on plans for the coming year, to request input on program elements where the agency is considering future changes and to identify areas where it is looking for improvements in plan performance. The Justice in Aging comments applauded CMS for much of the content of the draft. We noted specific areas where increasing complexity in plan design is making it increasingly difficult for beneficiaries to navigate the Part D benefit and urged CMS to continue rigorous review of formulary structure changes that create consumer confusion. We also argued for more translation of key beneficiary communications in the program. In addition to its own comments, Justice in Aging also joined twenty other advocacy organizations in a letter, spearheaded by the Medicare Rights Center, expressing strong support for CMS guidance requiring better adherence by plans to notice requirements for coverage denials in Part C and D and encouragement for CMS to explore ways to strengthen the appeals process and make it more accessible to beneficiaries.
