OPM proposes to amend the Federal Employees Health Benefits Acquisition Regulation (FEHBAR) to update reporting requirements for health insurance carriers providing benefits through the Federal Employees Health Benefits (FEHB) Program. In the course of business, FEHB carriers collect pharmacy, enrollment, provider, person-specific medical and pharmacy claims, or in the case of managed care plans, encounter data related to enrollees and family members in order to provide healthcare coverage to those individuals. Under this proposed regulation, FEHB carriers would be required to submit this information to OPM, related to all benefits and services provided under the Program, on no less than an annual basis. This rule clarifies the requirements for FEHB carriers to furnish such reasonable reports, pursuant to 5 U.S.C. 8910, to better enable OPM, as a health oversight agency, to obtain the information necessary for proper administration of the FEHB Program.
