Federal law requires that patients can not be denied emergency treatment due to an inability to pay. The hospitals write off the uncompensated care as bad debt. These costs cut into the revenues of healthcare corporations. Take for example Tenet Healthcare: From 2007-2009 the company reported net operating revenues of $26B but only $145M in profits. A profit of one-half of a penny for every dollar in revenue is not a good business model. Their annual report said: "...unless our business mix shifts toward a greater number of insured patients or the trend of higher co-payments and deductibles reverses, we anticipate this high level of uncollectible accounts to continue." Tenet and many others will continue to pass those costs on to the insured. Either insurance premiums will rise, co-payments will rise, basic coverage will be reduced, or any combination of the three. I wonder how many John and Jane Doe's have been admitted to the hospital this year.
