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.
Industry relationships: CMS Open Payments, as reported by manufacturers. Shown only above a threshold that excludes meals, travel and gifts, so most providers do not have this section.
Registry details: NPPES. Subspecialties are self-reported at registration, not a board certification.
Credentials: Doctor of Osteopathic Medicine (DO)
A DO degree indicates completion of an osteopathic medical program, which includes the same medical training as an MD with additional emphasis on the musculoskeletal system and osteopathic manipulative treatment.
