Where this comes from
Procedure volumes:CMS Medicare Physician & Other Practitioners, 2024. Fee-for-service claims only, so they exclude privately insured, Medicare Advantage and pediatric patients - volume is not comparable across practices with different patient mixes. These are billing records, not outcomes.
Training and practice: CMS Doctors and Clinicians list. A graduation year is when training finished, not years of orthopedic experience or a board certification. Affiliations come from Medicare enrollment and may be incomplete.
Registry details: NPPES. Subspecialties are self-reported at registration, not a board certification.
