The most costly Medicare beneficiaries tend to include those who have multiple chronic conditions, those using inpatient hospital services, those who are dually eligible for Medicare and Medicaid, and those who are in the last year of life, says a recently released report by the Medicare Payment Advisory Commission (MedPAC). 

MedPAC's June 2011 Data Book contains information on national health care and Medicare spending as well as Medicare beneficiary demographics, dual-eligible beneficiaries, quality of care in the Medicare program, and Medicare beneficiary and other payer liability. The Data Book also examines provider settings and presents data on Medicare spending, beneficiaries’ access to care in the setting (measured by the number of beneficiaries using the service, number of providers, volume of services, or length of stay, or through direct surveys) and the sector’s Medicare profit margins, if applicable. In addition, it covers the Medicare Advantage program and prescription drug coverage for Medicare beneficiaries, including Part D.
