About this data

It lets the organization bill Medicare for the clinician's services and receive the payment. This page lists the clinicians whose reassignment to Aspirus Wittenberg Clinic appears in the CMS Revalidation Reassignment List.
Who is included. Clinicians who bill Medicare under their own NPI through this organization. A clinician can reassign to more than one organization, so the same name may also appear under other groups.
