Dataset Details
Data Summary
The CHOICE Institute hosts a variety of healthcare datasets which are available to the UW community under varying permission structures. A description of available datasets and access details are described below.
The Merative MarketScan® Atlas Package Databases contain longitudinal inpatient, outpatient, pharmacy claims, and insurance coverage data for patients across the U.S. who are covered by commercial, Medicare, and Medicaid plans. The inpatient and outpatient claims databases include procedure and visit level details from medical claims such as ICD-9-CM diagnosis and procedure codes, Current Procedural Terminology (CPT) medical procedure codes, dates of service, and variables describing financial expenditures. The pharmacy claims database provides details including National Drug Codes (NDC) of the drugs dispensed, dates dispensed, quantity and days’ supply, and payments made for each claim. A separate eligibility and demographics file includes additional information about each subject such as age, gender, insurance plan type, employment status and classification, geographic location, and enrollment status by month.
