Study by Milliman shows that cost-shifting from Medicare and Medicaid underpayments added $1,788 to a family health insurance cost in 2006-2007. This amounted to about 15% of the amount paid for hospital and physician costs for privately insured people. Premiums paid through employer-provided insurance were estimated to be 10.6% higher due to the cost-shifting. With medical inflation, the cost shift would be more than $2,700 in today’s dollars, or more than $225 on the monthly premium. Study was commissioned by the AHA (American Hospital Association), AHIP and Blue Cross Blue Shield Assn/Premera Blue Cross, released December 2008. Old study.
