NOTE: This analysis by hospital group is limited to data for hospitals that submitted all required data elements. Most revenue (and corresponding costs) from Medicaid health maintenance organizations and Medicare risk plans are included in the private payer category.

^a Gains or losses as a percentage of total costs for each of the six sources of revenue shown sum to total gains as a percentage of total costs. The values shown would be slightly lower if expressed as total margins, where total gains are calculated as a percentage of total revenue rather than total costs.

^b Medicare and Medicaid costs equal all costs, both inpatient and outpatient, attributed by hospitals to these programs' patients regardless of whether the costs are reimbursable by the programs.

^c Operating subsidies from state and local governments were considered as payments for uncompensated care, up to the level of each hospital's uncompensated care costs. Additional subsidies above this level were counted as separate revenue.
