What this record establishes
CMS published hip or knee replacement services under this surgeon's NPI.
What still needs verification: current AAHKS membership, years in practice and board certification. An unmet criterion is never a finding against a surgeon: CMS publishes only the Medicare half of a practice, and a credential nobody has documented is unknown, not absent.
How each fact was established
Joint-replacement fellowship verified
Adult reconstruction fellowship — Brigham and Women's Hospital / Harvard Medical School. Read on the cited page.
The Emerson Health provider page lists his training as medical school at the University of Massachusetts Medical School, internship and residency in orthopedic surgery at the University of Pennsylvania, and a fellowship at "Brigham and Women's Hospital, Harvard Medical School (Hip and Knee Replacement Surgery)". His practice's own page states the same fellowship in the same words. No completion year is given on either page.

Joint replacement volume
129 primary hip and knee replacements were published under this NPI in 2024 Original Medicare fee-for-service claims (74 hip, 55 knee). That is a lower bound: cash and commercially insured cases are published nowhere, for anyone. Above the 100 the criterion asks Medicare to show, the unpublished half is assumed to at least match it, which is how the 200-a-year criterion is credited: half counted, half assumed.
Medicare participation: accepts Medicare assignment
The CMS Doctors & Clinicians file reports that this clinician accepts the Medicare-approved amount as payment in full.
CMS Medicare-listed practice: Orthopedic Affiliates Inc · Concord, MA 01742.
AAHKS membership
Not linked to the authenticated AAHKS roster. This is not a finding that the surgeon is not a member.
Board certification
American Board of Orthopaedic Surgery certification is not covered by the retained dataset and has not been checked.
Is this your record?
A surgeon may correct their own page. Sign in as a physician, confirm the NPI on this record, and verify with a code texted to your cell phone. You can then correct the practice, fellowship and start-year fields, or ask for the page to come down. Corrections appear here as stated by you, beside what the public sources show.
Report an error in this record
Anyone may report an error: a patient, a practice, a colleague, or the surgeon. A person reads every report and checks it against a source before anything on the page changes. You can also write to privacy@sherlockhealth.ai.
This is a documented record, not a rating or a recommendation. It carries no stars, scores, ranks or badges. Every fact names its source and the date it was read; a fact nobody has documented reads “not yet documented,” which is a gap in the record and never a finding about the surgeon. Whether a surgeon is right for you is decided in an examination, by you and them.
