What this record establishes

The authenticated AAHKS directory lists this surgeon as a member, and CMS holds a provider record for this surgeon.

What still needs verification: board certification and current all-payer annual volume. 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 — source not yet found

Adult reconstruction fellowship — OrthoCarolina. The cited page was read and does not state this fellowship. The claim came from a search result, and a source that states it has not been found yet.

Kaiser Walnut Creek surgeon completed a Hip & Knee Reconstructive Surgery fellowship at OrthoCarolina (2012-2013).

Years in practice

About 13 years, estimated from training dates. The estimate allows six years for residency and fellowship, which is the shortest path there is, so the real figure may be lower.

Joint replacement volume

CMS published no 2024 Original Medicare hip or knee replacement services under this NPI. That is not a finding of low volume: the file cannot answer the question for this surgeon.

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: Permanente Medical Group Inc · Walnut Creek, CA 94596.

AAHKS membership

Listed in the authenticated AAHKS member directory as Fellow 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.
