Janice S. was also charged $157.61 for a CBC — the complete blood count that those of us who are ER aficionados remember George Clooney ordering several times a night. Medicare pays $11.02 for a CBC in Connecticut. Hospital finance people argue vehemently that Medicare doesn’t pay enough and that they lose as much as 10% on an average Medicare patient. But even if the Medicare price should be, say, 10% higher, it’s a long way from $11.02 plus 10% to $157.61. Yes, every hospital administrator grouses about Medicare’s payment rates — rates that are supervised by a Congress that is heavily lobbied by the American Hospital Association, which spent $1,859,041 on lobbyists in 2012. But an annual expense report that Stamford Hospital is required to file with the federal Department of Health and Human Services offers evidence that Medicare’s rates for the services Janice S. received are on the mark. According to the hospital’s latest filing (covering 2010), its total expenses for laboratory work (like Janice S.’s blood tests) in the 12 months covered by the report were $27.5 million. Its total charges were $293.2 million. That means it charged about 11 times its costs. As we examine other bills, we’ll see that like Medicare patients, the large portion of hospital patients who have private health insurance also get discounts off the listed chargemaster figures, assuming the hospital and insurance company have negotiated to include the hospital in the insurer’s network of providers that its customers can use. The insurance discounts are not nearly as steep as the Medicare markdowns, which means that even the discounted insurance-company rates fuel profits at these officially nonprofit hospitals. Those profits are further boosted by payments from the tens of millions of patients who, like the unemployed Janice S., have no insurance or whose insurance does not apply because the patient has exceeded the coverage limits.
