CMS Administrator Mark McClellan on Monday said that no more than 100,000 Medicare beneficiaries have outstanding problems regarding glitches in the payment of drug plan premiums through monthly Social Security checks, CQ HealthBeat reports. McClellan said, "When people were switching plans or initially enrolling, we probably did have hundreds of thousands with problems. At this point, we're down to probably about a hundred thousand that have issues that are not completely resolved, and we are working with Social Security to resolve the remaining cases" (Reichard, CQ HealthBeat, 9/25). A glitch last month caused the government to erroneously reimburse about 230,000 Medicare beneficiaries for their prescription drug benefit premiums. CMS administers the drug benefit and the Social Security Administration deducts some beneficiaries' premiums from Social Security checks. The New York Times on Monday reported that the erroneous payments were the latest of several mistakes in the "strained, often dysfunctional relationship" between CMS and SSA (Kaiser Daily Health Policy Report, 9/25). McClellan said, "Every week, we get a significant number of these remaining ones resolved, and I expect these to continue to stay on track for resolution in the weeks ahead" (CQ HealthBeat, 9/25).
