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 administers the federal marketplace; some states run their own. Plans are categorized as Bronze, Silver, Gold, Platinum, plus catastrophic.
How it shows up in your practice
Verify ACA plan eligibility carefully — many plans have narrow networks. Cost-sharing reductions (CSRs) only apply to Silver-plan enrollees at certain incomes.
