Profile of Insurance Coverage in a National Inpatient Sample

Medicare was expected to cover nearly half of all inpatient admissions; however, hospitals showed a wide range of percentages for all payers, and some facilities reported up to 61.5% of visits from uninsured patients.

Results suggest that reimbursement policy changes may disproportionally impact certain hospitals based on their characteristics and/or patient distribution and may be particularly informative in the current era of potential system-wide reform.
