Requesting Maryland Medical Assistance Data - Frequently-Asked Questions

Step 1: Beginning your Data Request

Who do I contact at Maryland Medicaid for assistance with Data Requests?
John Parrish, Regulatory Economist III, is the point person at MDH for starting the Data Request process. Mr. Parrish can be contacted via email at  or via phone at (410) 767-5808. We encourage the principal investigator or study coordinator to schedule a teleconference with Mr. Parrish early in the process, as an opportunity for her/him to pose questions, comments and concerns (e.g., tight timelines for deliverables) at the very front end of the process. During such a teleconference, Mr. Parrish will provide an overview of Medicaid’s processes and procedures.

Pooja Regmi, Lead Analyst, is the point person for any and all Data Use Agreement (DUA) concerns after the beginning of the generation of the DUA. Ms. Regmi can be contacted via email at or via phone at (410) 767-5943.
What happens after I submit a Maryland Medicaid data request form to the Maryland Medicaid Planning Administration team? 
The form is reviewed for completeness and clarity. A teleconference is scheduled, during which the purpose, scope and specifications of the proposed data pull are discussed and further defined. Once the specifications are refined, the request is forwarded to the team at the Hilltop Institute at UMBC responsible for providing the requested data. This team independently reviews the specified data request for feasibility and cost as well as clarity, and schedules a teleconference with the principal investigator to discuss perspectives and recommendations for optimization of the pending data pull.
What happens after the parameters of the data request and relevant data mining criteria, such as diagnostic codes, revenue codes, etc., are fully defined?
A statement (i.e., narrative description) of the agreed upon parameters, referred to as the Scope of Work statement, is drafted and reviewed by all involved parties. Relevant data mining criteria (such as codes and other identifiers) are appended to this statement. Upon request, the Hilltop team can provide a sample statement of the Scope of Work to serve as guidance when the research team takes next steps to draft such a narrative. To the extent necessary, the Hilltop team provides technical assistance to the research team during the drafting of this statement. After undergoing a rigorous review, this statement is finalized.
Is there a cost associated with the fulfillment of my data request?
Yes. This cost is estimated based upon the finalized statement of the Scope of Work. 
What must I submit along with my data request?
As soon as feasible, the principal investigator submits the following to the Maryland Medicaid Planning administration team (John Parrish, Regulatory Economist III is the point person at MDH for starting the Data Request process. Mr. Parrish can be contacted via email at or via phone at (410) 767-5808):  (1) finalized statement of the scope of work; (2) that information needed from the principal investigator to customize templates for the Inter-Agency Agreement (IA) and the Data Use Agreement (DUA); and (3) a drafted MDH IRB application.
