Payment totals shown for the latest published program year (2024). Presence of disclosed payments is not, on its own, a conflict of interest. Physicians dispute records directly with CMS (dispute process). How we show this.
Open Payments figures as displayed on . Corrections flow from the manufacturer through CMS and are adopted on our next refresh.
What this page is: a republication of public federal NPI Registry records, filtered to the medical oncology taxonomy. It is not a directory we curate, and inclusion is automatic based on each provider's own NPI filing with CMS. Providers who believe their NPI record is inaccurate should update it directly with CMS at npiregistry.cms.hhs.gov; our next refresh adopts the corrected federal record.
Practice info disclaimer: Provider addresses and phone numbers come from the NPI Registry, which providers update at their discretion. Always call ahead to confirm the provider is currently accepting patients and is at the listed address.
