UPMC physicians and nurse practitioners on the CMS clinician file
3,714 physicians and nurse practitioners bill Medicare under a UPMC facility name, 0.4% of the 1,011,505 on the CMS Doctors and Clinicians file.
3,166 of them are physicians and 548 are nurse practitioners.
That is rank 6 of the 7 health systems whose facility names match cleanly enough to count.
This is a count of Medicare-enrolled clinicians carrying the system's facility name, not the system's headcount.
