Health care debt is a widespread problem in the United States. Medicare offers coverage for a range of health care services, including hospitalizations, physician visits, prescription drugs, and post-acute care, but Medicare beneficiaries generally pay out-of-pocket for their monthly premiums and deductibles, cost-sharing for Medicare-covered services, and the cost of services not covered by Medicare.
