What this provider does (Medicare)
Based on Medicare fee-for-service claims, 2024; not all care is captured.

Typical Medicare-allowed amounts for these services range $6–$76 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, and not what you would be billed. Medicare Part B covers roughly an eighth of all NPIs (65+ skew); services with fewer than 11 beneficiaries are suppressed by CMS.

Transparency — industry payments
Based on CMS Open Payments, 2024; not all care is captured.
$639 across 18 records (Open Payments 2024)
Open Payments discloses payments and transfers of value (meals, travel, consulting, research, royalties) from drug and device makers to providers. 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.
