Red Flags Explained
▼
Each flag represents a statistical test that identified unusual billing patterns. Here's what each flag on this provider means in plain English:
Cost Outlier
Cost Outlier means this provider charges significantly more per claim than other providers billing the same procedure codes. This could indicate upcoding, inflated charges, or specialized services that justify higher costs.
Rate Outlier
Rate Outlier means this provider charges above the 90th percentile for multiple different procedure codes simultaneously. While one high-cost code could reflect specialization, consistently high rates across many codes may indicate systematic overbilling.
These flags are statistical indicators only. Many flagged providers have legitimate explanations for their billing patterns. Learn more about our methodology.
