IBM® Marketscan® Research Databases
The IBM® Marketscan® Research Databases contain individual-level, de-identified healthcare claims information from employers, healthplans, and Medicaid programs. CoDES has active licenses for the IBM® Marketscan® Commercial Database, IBM®Marketscan® Medicare Supplemental Database, and IBM® Marketscan® Health Risk Assessment Database.
The IBM® Marketscan® Commerical database includes 2005-2018 health insurance claims for inpatient, outpatient, and outpatient pharmacy encounters, as well as enrollment data from large employers and health plans across the United States who provide healthcare coverage for their employees, their spouses, and dependents. The current dataset includes >180 million lives.
The IBM® Marketscan® Medicare Supplemental Database includes 2005-2018 enrollment records along with inpatient, outpatient, ancillary, and drug claims for 12.5 million retirees in the United States with Medicare supplemental coverage through privately-insured fee-for-service, point-of-service, or capitated health plans.
The IBM® Marketscan® Health Risk Assessment (HRA) Database includes 2012-2018 self-reported biometric and health-related behavioral data obtained through surveys of employees of large US corporations and health plans. HRA is linked to medical, pharmacy, and enrollment data for these employees in the IBM® Marketscan® Commercial Database and used to examine the relationships between health behaviors/risk and health outcomes or medical expenditures. Linked data is available for about 5% of beneficiaries.
Medicaid Analytic eXtract (MAX) and T-MSIS Analytic Files (TAF)
MAX and TAF data contain claims for medical care and drug benefits received by beneficiaries with Medicaid insurance coverage, the state-run programs for low-income and categorically eligible individuals and families.

Medicare fee-for-service claims data
Medicare is a federal health insurance program that provides coverage to people aged 65 years or older and those with disabilities or end-stage renal disease. Annual Medicare enrollment has exceeded 50 million since 2012. Data include claims for inpatient, skilled care nursing facility, and hospice care (Part A) as well as outpatient care (Part B) and prescription drugs (Part D).
