Frequently Asked Questions

1. Are Claim and Claim Line Feed (CCLF) files going away?

No, CCLF files are not going away. BCDA is meant to supplement the data that ACOs already receive for the Shared Savings Program or other eligible model participation, which may include CCLF files. Please contact SharedSavingsProgram@cms.hhs.gov or your respective model with questions about CCLF files.

2. Can my ACO use BCDA?

  • Currently, all Medicare Shared Savings Program ACOs are able to use BCDA. Please generate BCDA credentials using the ACO Management System (ACO-MS).
  • BCDA is evaluating support for models developed by the Center for Medicare and Medicaid Innovation. If your ACO is interested in using BCDA, please contact your respective model. As additional ACO models are able to use the API, we will share information on this website and in BCDA's Google Group.
  • You don't need credentials to use the sandbox environment. All ACOs and their vendor partners are encouraged to try the API in the sandbox environment with synthetic data.

3. How can I share my feedback?

BCDA is built in accordance with feedback from ACOs and their vendor partners. You are invited and encouraged to share feedback with CMS when using BCDA in sandbox or production to ensure we are creating an API that meets your organization’s needs. Join BCDA’s Google Group to connect with other participating organizations and BCDA’s research and development team.

The Latest & Greatest from BCDA!

Changes to BCDA for new year attribution are over. The 'runout' filter is still available.
January 25 2020
As promised, BCDA has retrieved the January attribution file and the temporary changes implemented during the end of year have been reset. Requests to /Patient and /Group using `all` have returned to their normal state of operation. In addition, you can continue to use /Group with `runout` to retrieve claims runout data for beneficiaries who were attributed to your ACO in 2020 but not in 2021. These claims will have a service date no later than December 31, 2020. Please consult the Building Your Application page for guidance on using the `runout` attribute.
