Signal Tiers and Evidence Bases — Minnesota Medicaid Transparency Project
Author: Minnesota Medicaid Transparency Project | Last updated: September 26, 2026
How this project tiers its fraud signals and what each kind of evidence can support. Covers the three referral tiers, the five evidence bases, why adjudicated actions are reported in the past tense with an as-of date, why a missing licence record is not a finding that a provider is unlicensed, and how identity is proved per record.
Part of the Minnesota Medicaid Transparency Project — an independent, data-driven investigation of $23 billion in annual Medicaid spending across 87 counties.
