The Medicaid claims data files contain claims from FY’08 to present. The database is comprised of five different files:
Medical claims (date of claim, diagnoses, Current Procedure Terminology Codes)
Prescription claims (date of claim, National Drug Codes)
Client demographics (gender, race, birthdate)
Client Supplemental (eligibility, aid category, Primary Care Physician, Family ID, address)
Provider data (address, Provider identification number)
The Medicaid claims database contains a Master Client Index (MCI) variable which allows the files to be linked together. All individuals in programs within the Delaware Department of Health and Social Services (DHSS) use the same identifier which allows linkage of data across divisions.
