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 Mesa Counseling Services 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.
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.
