Transparency — industry payments
Based on CMS Open Payments, 2024; not all care is captured.
$8,461 across 14 records (Open Payments 2024)

This is a transparency signal, not a verdict — such payments are legal and common, and their presence is neither an endorsement nor a criticism. Source: CMS Open Payments, program year 2024.
