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 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. DOs are fully licensed physicians who can prescribe medication, perform surgery, and specialize in any medical field including orthopedic surgery.
