Faxing medical forms
Doctors' offices, clinics and insurers still run on fax. These guides cover the whole trip, from a readable scan to proof that the right pages arrived.

Why medical offices still ask for a fax
A fax goes from one machine to another number the office controls, and the receiving machine confirms each page. That is why referrals, records requests, prior authorizations and insurance forms are still faxed every day. You don't need a fax machine to send one - your iPhone camera and an app are enough. Start with sending medical forms to a doctor's office by fax.
Three things that decide whether it works
- A readable scan. Small print, signatures and checkboxes are what gets lost. Flat page, good light, high contrast - see how to scan documents for a fax.
- A clear cover sheet. The patient's name, a callback number, who the fax is for and the page count. The cover sheet guide shows what to include and what to leave off.
- Proof it arrived. Keep the delivered record with the time and page count, and call if you don't hear back - how to confirm a fax was received.
If the office needs to fax something back to you, you need a fax number of your own for a while: how to receive a fax on iPhone.
