Where this comes up
Front-office and billing both hit this term — eligibility before the visit, prior auth before the procedure, contract terms during fee-schedule negotiation, and credentialing whenever a new provider joins or a payer roster lapses. Misses here become denials downstream.
Full definition
What it is in practice
CMS PPDR gives patients a federal complaint pathway. Providers may face a downward adjustment if the disputed charge significantly exceeds the GFE.
How it shows up in your practice
Ensure GFE accuracy. Major variances are the primary risk; build review when actual charges trend above estimate.
