Submit your usual enrollment changes timely, or you'll be sorry. "The Medicare provider enrollment revalidation effort does not change other aspects of the enrollment process," CMS says in an e-mail message to providers. "Providers should continue to submit routine changes -- address updates, reassignments, additions to practices, changes in authorized officials, information updates, etc. -- as they always have." Even if you receive a revalidation request, you need to submit your changes separately from your revalidation information, CMS stresses.
