Single-test outliers in Washington Medicaid data. These are individual statistical flags β most are informational.
Important context: These findings identify statistically unusual billing patterns, not determinations of wrongdoing. Cost-per-claim comparisons may flag hospital outpatient departments whose reimbursements include facility fees, bundled services, or all-inclusive rates. High claims-per-beneficiary ratios may reflect legitimate care patterns at behavioral health facilities, pediatric specialty centers, or residential care programs. Additional investigation and clinical context are required before drawing any conclusions.
For provider level analytics using multiple independent tests, see the Watchlist β which flags providers only when 2+ different detection methods agree. These single-test outliers below are primarily informational; only Cost Outliers and Overutilization are flagged as critical/warning.
