Govexec.com reported yesterday that over 400,000 federal employees and annuitants enrolled in the new supplemental dental program and over 300,000 enrolled in the new supplemental vision program. “Of the dental insurance, MetLife was by far the most popular, with more than 250,000 enrollees. BCBS took the lead for vision insurance with more than 198,000, according to OPM data.” Rep. Tom Davis (R Va.) wrote a letter to OPM Director Linda Springer encouraging her to “identify ways that the federal government can leverage this large pool to ensure that participants are receiving the best dental and vision products and services at the lowest cost to the participants.”
