Cms Blue Button Plans Pricing
Blue Button 2.0 is a free U.S. government API operated by the Centers for Medicare & Medicaid Services. There is no paid tier, no metered billing, and no commercial plan - access is gated by process rather than by price. The sandbox is fully self-serve with synthetic data for 10,000 Medicare enrollees. Production access requires CMS approval of the application - a public privacy policy and terms of service, an application form, and a one-hour demo to the CMS team - after which production credentials are issued at no cost. Refresh tokens (13-month and research application types) are granted as part of that approval.
