The IBM® MarketScan® Commercial Claims and Encounters Database from IBM Watson Health® contains de-identified, patient-specific health data of reimbursed healthcare claims for employees, retirees, and their dependents of over 250 medium and large employers and health plans. Hence, individuals included in the database are covered under private insurance plans; no Medicaid or Medicare data are included. These data cover approximately 30 million covered employees and family members per year.
The MarketScan Commercial Claims and Encounters Database is divided into subsections including:
- Inpatient Claims file
- Outpatient Claims file
- Outpatient Prescription Drug Claims file
- Enrollment Information file
- RED BOOK™ Supplement (includes variables related to drug prescription)
