Why healthcare still runs on fax
Fax remained the default in US healthcare largely because it was explicitly carved out as acceptable under HIPAA while email was not, and because it works between organisations that share no systems at all. A clinic, a pharmacy, and an insurer with three incompatible record systems can all receive a fax.
For a patient, that means being told to fax a records release, a prior authorization, or an FMLA form — usually by an office that will not accept it any other way.
