The condition category variables are claims-based algorithms to indicate whether treatment for the condition appears to have taken place.
All of the variables listed on this page are currently available in the Master Beneficiary Summary File (MBSF), Medicare-Medicaid Linked Enrollee Analytic Data Source (MMLEADS) and Medicaid Enrollee Supplemental File (MESF).
Researchers may request data for a specific, predefined cohort based on any of the categories on this page.
