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 Stars drives MA plan quality bonus payments. Plans with 4+ stars receive quality bonus payments; 5-star plans get a year-round enrollment window.
How it shows up in your practice
Many MA contracts include shared incentives tied to Stars measures. Pay attention to HEDIS-derived measures and patient experience scores.
