  • Why should I register with the Data Access Hub?

    Registering for the Data Access Hub offers users more granular information about the Commercial Claims dataset. It is also a requirement for anyone looking to apply for a license to access the data. HCCI uses your contact information solely for communication purposes, and to offer support to our data users along the way. The non-disclosure agreement included in the registration process is a mutual agreement that protects the confidentiality of HCCI’s data details while also protecting the confidentiality of your application contents, (e.g. research questions, proposed methods, etc.) Should you have any concerns, please contact us at This email address is being protected from spambots.

  • What do I need to do to apply?

    The HCCI team will review and approve your registration for the Data Access Hub, then you can submit an application to license access to the commercial claims dataset electronically. Once an application has been subject to the internal review process, it is submitted to the Data Integrity Committee for external review. After approval, researchers will complete compliance paperwork right before access to the secure data enclave environment is provisioned. Now teams can begin their research. We encourage you to review our HCCI 2.0 Overview Deck for more insight.

  • Do I need IRB approval?

    The data is de-identified, therefore HCCI does not have any IRB requirements. We do advise you to consult with your organization’s IRB regarding your need for approval.

  • What is the cost to access the data?

    HCCI offers access on a per project basis. Team access is $45,000 for a one-year term. Student access includes 1 seat in the data for $15,000 for a one-year term. Renewal options and additional seats for team access are available. If your institution is interested in broader access, we can discuss details, which include the opportunity for volume discounts if you initiate multiple projects. We encourage you to review ‘Pricing Details for Access’.

  • Do you offer institutional memberships or discounts for multiple projects?

    Yes. HCCI offers a volume discount on additional projects that are initiated within the first year of data access. If you (or other researchers in your institution/organization) apply and are approved for 1 additional project within the year, it will be discounted by 5%. For 2 additional projects within the year, both projects will be discounted by 10%, and 3 additional projects will be discounted by 15%. HCCI caps the discount at 15% for 4 or more projects, as our fixed costs associated with acquiring and maintaining the dataset will not allow for deeper discounting.

  • Does my year of access allow me to do unlimited projects?

    No. One-year access is limited to the research proposed within your application. However, you are welcome to write your research proposal to allow for multiple research questions (while maintaining a cohesive focus), and to publish results in multiple papers. Additionally, per HCCI’s volume discount program, you can apply for additional projects during your year of access and receive a discount that increases with the number of additional projects.

  • Do I need certain storage requirements to access the data?

    Approved research teams get access to our entire dataset within the secure enclave — this includes all years, all billion+ claims. We do not send physical data.

  • How long will it take for me to get access to the data?

    Once your application has been submitted, it goes under review for up to eight weeks. For a more in-depth look into the approval process, please see our HCCI 2.0 Overview Deck.

  • I’m not going to finish my project in the year-long access window. What are my extension options?

    HCCI offers 90-day extensions, one-year extensions or multi-year extensions, (annual cost at the time of agreement applies).
