COLUMBIA, S.C. — People shopping for insurance on the federal marketplace may be informed they’re eligible for Medicaid and that their information is being sent to state officials to sign them up. However, states say they aren’t able to enroll them because they’re receiving incomplete data from the Obama administration.

The Center for Medicare and Medicaid Services wrote a memo to the 36 states using the federal website last week acknowledging the information wasn’t being transferred automatically and saying another system was being developed to send it. More complete files could be sent as soon as next week.
