Center for the Study of Services

CSS develops and implements the first nationwide survey of health plan members for public reporting, surveying 150,000 members of 265 health plans participating in the Federal Employees Health Benefits (FEHB) program. CSS designed the survey, drew the sample, fielded the survey, and analyzed the data. Since 2000, CSS has been responsible for analyzing all of the HEDIS/CAHPS data for the FEHB program for the U.S. Office of Personnel Management (OPM).
