64 FR 36271SUPPLEMENTARY INFORMATION: The purpose of this regulation is to implement the portion of the Defense Authorization Act for 1999, Public Law 105-261, that amended chapter 55 of title 10, United States Code, and chapter 89 of title 5, United States Code, to establish a demonstration project under which certain Medicare and other eligible DoD beneficiaries can enroll in health benefit plans under the FEHB Program. The legislation was signed into law on October 17, 1998. The demonstration project will run for a period of three years from January 1, 2000, through December 31, 2002. DoD, with OPM concurrence, has selected eight geographic areas to serve as demonstration project areas. The legislation requires that between 6 and 10 geographic areas be selected. No more than 66,000 individuals can participate in the demonstration project at any one time. Beneficiaries who are provided coverage under the demonstration project will not be eligible to receive care at a military medical treatment facility or to enroll in a health care plan under DoD's TRICARE program. Individuals who disenroll or cancel enrollment from the demonstration project are not eligible to reenroll in the demonstration project. OPM will establish separate risk pools for developing demonstration project enrollee premium rates. The Government contribution for demonstration enrollees will be paid by DoD and cannot exceed the percentage that the Government would have contributed had the enrollee been enrolled as a regular FEHB enrollee in the same health benefits plan and level of benefits. The legislation requires OPM and DoD to jointly produce and submit two reports to Congress designed to assess the viability of expanding access to the FEHB Program to certain Medicare and other eligible DoD beneficiaries permanently. The first report is due by April 1, 2001; the second is due by December 31, 2002. The reports will focus on enrollee participation levels, impact on Medicare Part B enrollment, impact on premium rates and costs as compared to regular FEHB enrollees, impact on accessibility of care in military treatment facilities, impact on medical readiness and training in military treatment facilities, impact on the cost, accessibility, and availability of prescription drugs for DoD beneficiaries, and recommendations on eligibility and enrollment. OPM has determined it necessary to specify certain differences from existing FEHB Program regulations because of the unique features of the demonstration project. This regulation amends chapter 16 of title 48, Code of Federal Regulations (CFR) to enumerate these differences. When developing premium rates for demonstration project community- rated carriers, OPM will not use similarly sized subscriber group (SSSG) rating methodologies to determine the reasonableness of the carrier's demonstration project premium rates. We are not using SSSG's because we have learned from our consultations with community-rated carriers that
