Sav-Rx, an independent PBM, still accepts fax for prior authorization and prescriptions, with two separate numbers.
Who This Page Is For
Providers and pharmacies submitting a prior authorization request or prescription documentation to Sav-Rx, an independent pharmacy benefit manager.
Sav-Rx confirms two separate, current fax numbers on its own site: (888) 810-1394 for Prior Authorization requests, and (402) 753-2890 for general prescription fax. Nothing on savrx.com frames either as being phased out. Email (PriorAuth@SavRx.com) and a portal through Sav-Rx's processor, MedImpact (pharmacy.medimpact.com), exist as alternatives, not stated replacements.
Fax number(s) verified 2026-09-17.
Nothing has replaced fax. Email and a MedImpact-hosted portal coexist as alternatives, useful when a provider's system already integrates with MedImpact, but Sav-Rx's own materials don't frame fax as legacy.
Several other pharmacy prior authorization intermediaries follow a similar pattern. Our directory also covers eviCore's fax number, is fax still accepted at CVS Caremark, the OptumRx fax page, and Prime Therapeutics's prior authorization fax, each with its own fax status and routing notes.
Fax.Plus stores Sav-Rx prior authorization and prescription faxes with 256-bit AES encryption at rest, unique key per user.
Yes, Prior Auth requests fax to (888) 810-1394, while general prescription faxes go to a different number, (402) 753-2890.
Sav-Rx directs providers to email (PriorAuth@SavRx.com) and a portal through its processor MedImpact (pharmacy.medimpact.com) as alternatives, not as stated replacements for the fax option.
