Methodology. The Actuarial Research Corporation under
contract with the Department of Health and Human Services conducted most of the
analysis. The basis for the estimates is the Medicare Current Beneficiary
Survey (MCBS) for 1995. These data were aged to CY 2000, converted to a
point-in-time estimate, and adjusted for the increase in managed care
enrollment. This enrollment increase was estimated by moving beneficiaries from
retiree health coverage, Medigap and the uninsured to managed care in
proportion to their enrollment in those plans.
