eviCore: Is There a Fax Number for Prior Authorization?

Is there a fax number for eviCore prior authorization?

eviCore's own FAQ and getting-started content routes providers through health-plan-specific instructions on its Provider's Hub and web portal for starting a new request. Fax is mentioned mainly as a channel eviCore uses to send back determination letters, auto-populated from the requestor's own fax number, not as the way to submit a new request. Some fax numbers surfacing in search results trace to PDF resource forms tied to specific health plans or service lines (for example, home health authorization), not a general current eviCore-wide fax line, so this page does not present a single canonical number.

Where fax fits

• New prior authorization request (provider): not by a general fax, use the Provider's Hub or your health plan's specific eviCore instructions. Source: eviCore's own Getting Started page.
• Determination letter, returned by eviCore (eviCore to provider): sent to the fax number on file for the original request. Source: eviCore's own Common Questions page.
• Service-specific authorization, for example home health (provider): fax number printed on that specific plan/service form. Source: the plan-specific form, varies.

What replaced fax at eviCore?

eviCore's Provider's Hub portal and each health plan's own routing instructions are the actual entry point. There was never one universal eviCore fax number to retire, the structure has always been plan-by-plan.

Which route should I use?

1. Start at eviCore's Provider's Hub or check the specific health plan's instructions for routing to eviCore, don't search for one general fax number.
2. If a plan-specific form provides a fax number for a particular service line, use that number, not a number found elsewhere.
3. If eviCore already has an open case and is sending back a determination letter, that goes to the fax number already on file for the original request, not a new number you choose.
