Military Health Care: Cost Data Indicate That TRICARE Reserve Select Premiums Exceeded the Costs of Providing Program Benefits

摘要

In 2006, the premium for both individual and family coverage under TRS--which DOD based on Blue Cross and Blue Shield (BCBS) premiums--exceeded the reported average cost per plan of providing TRICARE benefits through the program. TRS currently serves less than 1 percent of the overall TRICARE population, and unlike most other TRICARE beneficiaries, TRS enrollees pay a premium to receive health care coverage. At the time of GAO's analysis, TRS consisted of three tiers, established by law, with reservists in each tier paying different portions of the total premium, based on the tier for which they qualified. Over 90 percent of reservists who purchased TRS coverage enrolled in tier 1. The premium for individual coverage under tier 1 was 72 percent higher than the average cost per plan of providing benefits through the program. Similarly, the premium for family coverage under tier 1 was 45 percent higher than the average cost per plan of providing benefits. DOD based TRS premiums on BCBS premiums because, at the time DOD was developing TRS, actual data on the costs of TRS did not exist; however, these data are now available. Had DOD been successful in establishing premiums that were equal to the cost of providing benefits in 2006, the portion of the premium paid by enrollees in tier 1--which is set by law to cover 28 percent of the full premium--would have been lower that year. Reasons that TRS premiums did not align with benefit costs included differences between the TRS and BCBS populations and differences in the way the two programs are designed, which DOD did not consider in its methodology. According to experts, the most successful methods for aligning premiums with actual program costs involve using program cost data when setting premiums. The regulation governing TRS premium adjustments allows DOD to use either BCBS premiums or other means as the basis for TRS premiums. However, DOD officials told GAO that they plan to continue, at least for the near future, to base TRS premiums on BCBS premiums because of limitations associated with using currently available data to predict future TRS costs.
