More than three months after ObamaCare's launch, the Centers for Medicare and Medicaid Services (CMS) is developing a system to track enrollees who have made premium payments. The CMS would be able to track premium payments through the "834 form" generated on the back end of the system and transmitted from HealthCare.gov to the insurers when someone selects a plan online. A CMS official told The Hill some issuers were already providing these "effectuated 834 transaction forms," which will eventually be "the mechanism for making payment and reporting enrollment data as part of our automated system."
