Federal regulators have blocked two private sector enrollment websites from accessing consumer information through the federal Obamacare marketplace, citing "anomalous activity."

The unusual step comes as the Centers for Medicare & Medicaid Services is under the gun to curb unauthorized enrollment and switching of Affordable Care Act plans by rogue agents. The agency received more than 200,000 complaints in the first six months of the year about such actions.

CMS said in a written statement that it had suspended the two sites — Benefitalign and Inshura — "while the anomalous activity is researched to ensure the EDE partners are in compliance with CMS data standards." EDE stands for "enhanced direct enrollment" and refers to websites approved to integrate with healthcare.gov.
