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.
Credentials: Doctor of Medicine (MD)
An MD degree indicates completion of a medical doctorate program focused on allopathic medicine. MDs complete four years of medical school followed by residency training in their chosen specialty.
