Medicare PDPs must pay back-claims, CMS says

Share this content:

Medicare Part D plans cannot refuse reimbursement for certain claims covering periods of retroactive enrollment, according to the Centers for Medicare & Medicaid Services.

Some plans have been wrongly denying claims for coverage in retroactive enrollment periods because the claims were not submitted before the March 31, 2007, deadline, according to a recent memo from Cynthia G. Tudor, director of CMS's Center for Beneficiary Choices Medicare Drug Benefit Group.

Beneficiaries who made payment during a retroactive eligible period are entitled to reimbursement, CMS said. A recent study from the Government Accountability Office found that dual-eligible beneficiaries did not pursue retroactive Medicare Part D payments last year because the government did not notify them of this right until March of this year. Many dual eligibles reside in nursing homes.
