Before arranging a visit
Confirm current services, ages treated, insurance, location, hospital affiliations and appointment availability directly with the practice. An active NPI does not verify current licensure, certification or practice status.
A registry specialty label does not establish that a clinician currently provides the particular care you need.

How to interpret these counts
CMS suppresses provider/service rows involving fewer than 11 beneficiaries. Services may repeat for one person, and beneficiaries cannot be added across rows. Facility/non-facility describes billing and does not establish a current hospital affiliation. These counts do not report case complexity, clinical outcomes or whether a treatment is appropriate for you.
