What is Blue Button?
Blue Button 2.0 from CMS is an API that contains four years of Medicare Part A, B and D data for 53 million Medicare beneficiaries.
This data reveals a variety of information about a beneficiary’s health, including type of Medicare coverage, drug prescriptions, primary care treatment and cost. Beneficiaries also have full control over how their data can be used and by whom, with identity and authorization controlled by MyMedicare.gov.
Blue Button 2.0 uses the HL7 FHIR standard for beneficiary data and the OAuth 2.0 standard for beneficiary authorization.
What is the Sandbox?
Our developer sandbox is a place where you build and test applications using our synthetic sample beneficiary data and get up and running with our API. We've created a number of helpful resources to get you started.
