Medicare: Cost Sharing Policies Problematic for Beneficiaries and Program

Testimony issued by the General Accounting Office with an abstract that begins "Medicare provides valuable and extensive health care coverage for beneficiaries. Nevertheless, significant gaps leave some beneficiaries vulnerable to sizeable financial burdens from out-of-pocket expenses. Medigap is a widely available source of supplemental coverage. This testimony discusses (1) beneficiaries' potential financial liability under Medicare's current benefit structure and cost-sharing requirements, (2) the cost of Medigap policies and the extent to which they provide additional coverage, and (3) concerns that Medigap's so-called "first dollar" coverage undermines the cost control incentives of Medicare's cost-sharing requirements. GAO found that Medicare's benefits package and cost-sharing requirements leave beneficiaries liable for high out-of-pocket costs. Medigap policies pay for some or all Medicare cost-sharing requirements but do not fully protect beneficiaries from potentially significant out-of-pocket costs such as prescription drug coverage. Medigap first-dollar coverage eliminates the ability of Medicare's cost-sharing requirements to promote prudent use of services.
