The Centers for Medicare and Medicaid Services withdrew an eagerly awaited report detailing how health insurance companies fared during the Medicare Advantage annual enrollment period after identifying faults in the data Wednesday.
The agency plans to issue a corrected report next week, according to a notice CMS published several hours after releasing the enrollment figures.

CMS did not specify what is wrong with the data and did not immediately respond to an interview request.
