About this feed

The Medicaid Managed Care dataset uses CMS' state Transformed Medicaid Statistical Information System (T-MSIS) data for Arizona, Michigan, Nevada, and New Mexico to identify various metrics for managed care plans within each state. These metrics are designed to allow users to compare plans in each state across different specialty areas (currently Pediatric Dental, Behavioral Health, and Prenatal OB/GYN). This dataset does not include all available data in T-MSIS but utilized a subset to calculate the individual metrics identified.

Trace any row back to its source file and reporting period:

SELECT d.__STATE, d.COUNTY, d.MCO_NAME,
       ff.TEMPORAL_START, ff.TEMPORAL_END, ff.CMS_FEED_MODIFIED
FROM DWV.MEDICAID_MANAGED_CARE d
