Check the dates on CMS’s website for your turn at revalidation. If you miss your deadline, you will be deactivated and have to start the enrollment procedure from the beginning and miss out on any reimbursements in the interim. And CMS will not retroactive any payments once your billing privileges’ are reinstated. You are responsible to revalidate by your due date even if you do not receive any notice from your MAC.
Also for home care providers, keep track of your referring physician’s enrollment status. You’ll need to confirm that the ordering physician’s enrollment is active, too. Claims will be denied for an inactive physician and again, no retroactive billing claims will be paid.
