What this record establishes

The authenticated AAHKS directory lists this surgeon as a member, and CMS published hip or knee replacement services under this surgeon's NPI.

What still needs verification: 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 volume

686 primary hip and knee replacements were published under this NPI in 2024 Original Medicare fee-for-service claims (301 hip, 385 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 Above the 100 the criterion asks Medicare to show, the unpublished half is assumed to at least match it, which is how the 200-a-year criterion is credited: half counted, half assumed.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.

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.
