Question: Will CMS validate the Exchange-assigned Subscriber ID against the policy start and end dates?

Answer: CMS will validate the Exchange-assigned Subscriber ID against FEPS enrollment data for policies offered through the Federally-facilitated Marketplace (FFM) only. The validation will be performed to ensure the Subscriber ID is valid for that plan variation. Start and end dates will not be validated.
