What the columns mean

Experience — years since the clinician’s medical-school graduation (when known).
Telehealth — the clinician reported providing telehealth (video/phone) visits.
Medicare patients — distinct Original-Medicare beneficiaries in the latest year; a volume signal, not a quality rating.
Assignment — “Accepts” means they accept the Medicare-approved amount as full payment (lower out-of-pocket for Medicare patients).
