Federal Employees Health Benefits program carriers have been told that next year they will be expected to reduce the number of medical errors and to finish carrying out improvements in mental health and substance abuse benefits that have been phasing in during recent years. The directives came in the Office of Personnel Management’s annual “call letter” to federal health insurance carriers that kicks off the annual discussions between the carriers and OPM over benefit levels and rates for the upcoming calendar year. Rates and specific coverage levels will be announced in the fall in preparation for the “open season” to be held in mid-November to mid-December in which eligible federal and postal employees and retirees may join the program or change plans or levels of coverage.
