MCDB Data Release

The Maryland Medical Care Data Base (MCDB) is Maryland’s All Payer Claims Database, and its maintenance and release are governed by COMAR 10.25.06. The process for applying for and acquiring MCDB data is provided below. Four separate files containing eligibility information, professional services claims, institutional claims, and pharmacy claims are available for each year. At this time, data for the years 2010-2014 are available for release in a standard extract defined by the data dictionary below. We expect 2015 data to be available mid-January of 2017.

The data dictionary for the standard extract for all years can be viewed/downloaded here.

* Re-Use fees apply for using existing released files for a different scope of work. A new application must be submitted for a different scope of work or project. See Step 9 below.

The steps below must be followed to apply for access to the data:

Step Description Timeline
1 Pre-Application
The Pre-Application provides MHCC staff with an overview of the research goals and includes an attestation that the applicant is aware of and able to comply with the data security standards. MHCC staff may ask for clarifications and will provide general feedback based on the pre-application information.  The staff will inform the requestor if their application is feasible enough to go forward with the main application.  
Response within 2 weeks of receipt
2 Main Application
The Main Application requires detailed project information, data management plans, and data specifications and there is a $200 main application fee.
Due by 3rd Thursday of Each Month
3 Data Release Review Committee
The Data Release Committee will review the main application for the qualifications of the applicant, appropriateness of the data for the research goals, whether data security and protections are adequate, and whether HIPAA regulations are thoroughly understood. The committee makes a recommendation to the Commission as to whether this application should be approved.
Meets on the 4th Thursday of Each Month
4 Institutional Review Board (IRB) Review and Approval is Required
MHCC has designated Chesapeake IRB, as the IRB for reviews of MHCC data.  Please submit applications on Chesapeake IRB’s website.  Any fees for the IRB must be paid directly to Chesapeake IRB and are independent of MHCC’s application and data fees. Other IRB’s may be used if they are currently registered by the U.S. Department of Health and Human Services and have current Federal wide Assurance approval.
Rolling Review
5 Commission Review
Once all materials have been reviewed by the Data Release Committee and they have recommended approval to the Commission, an IRB Approval must be received by the 2nd Thursday before the Commission meeting in order for the application to be reviewed by the Commissioners. The Commissioners have final authority to approve release of MCDB data. Unless agreed otherwise in the ensuing Data Use Agreement, terms of the Commissioner approval are valid for one year.
Meets on the 3rd Thursday of Each Month
6 Data Use Agreement (DUA)
Once the application has been approved by the Commissioners, the data recipient will be required to complete the MHCC DUA, which will incorporate the application and require sufficient data security protections. The sample template will be modified based on the individual application.
Rolling Review and Execution
7 Data Release
Data will be released upon execution of the DUA and payment of fees. Data will be made accessible for download via secure ftp.
Rolling Execution
8 Ongoing Reporting and Monitoring
All recipients of data will be required to report quarterly on data use and
active projects.  MHCC may review any project for compliance with the specified
DUA scope. 
Quarterly after release of data
9 Annual DUA Renewals
All DUA’s must be renewed and approved annually. For a different scope of work using previously released data, a new application with application fee and re-use fees are required, and this new application must be approved by MHCC prior to re-using the data. Re-use of previously released data costs $2000 per file per year for commercial use and $1000 per file per year for non-profit use. Application for a new year of data for a previously approved scope of work requires a new application and fees at the standard new application rates.
Annually after release of data
10  Data Destruction
Data recipients must submit a Certificate of Data Destruction at the expiration of the DUA or project, whichever occurs first, as specified in the DUA.
 Project or DUA end
