MedImpact: Fax Number for Prior Authorization

Is fax still accepted at MedImpact?

MedImpact's official prior authorization forms page confirms a current fax number, (858) 790-7100, for submitting prior authorization forms. Nothing on MedImpact's site frames fax as being phased out, electronic alternatives, direct EMR/EHR ePA, CoverMyMeds, and the Surescripts Prior Authorization Portal, are presented as options rather than a stated replacement.

Which route should I use?
