Provides for the determination of such amounts. Directs the Secretary of Defense to: (1) maintain the DOD health care efforts for Medicare-eligible covered military beneficiaries; (2) estimate the amount expended by DOD for FY 1997 for providing health care items and services to such beneficiaries; and (3) establish monthly targets for the number of such beneficiaries enrolled in the project necessary to meet DOD maintenance of health care efforts for such individuals. Limits to $65 million the annual payments to DOD for the project. Requires the Comptroller General, for each project year, to submit to the Secretaries and the Congress a report on the extent to which costs under the TRICARE program and the Medicare program have increased as a result of the project. Directs the Secretaries to modify the project at the end of each year to correct for any discrepancy between cost targets and actual spending under the project.
