About this data
Medicare reassignment. A clinician who works for a hospital, clinic or medical group usually signs a Medicare reassignment (form CMS-855R). It lets the organization bill Medicare for the clinician's services and receive the payment. This page lists the clinicians whose reassignment to Allen Hospital 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.
Nearest 250. The totals and specialty counts cover all 324 clinicians. The list shows the 250 whose practice address is closest to this NPI's location, so each Allen Hospital location shows its own nearest clinicians.
Addresses and phone numbers come from each clinician's own NPPES record, so they may point to another office or to the clinician's own practice.
