Best HIPAA-Compliant Fax for Therapists (2026), and What to Do With the Referrals
Therapy practices still need a fax number: referrals from pediatricians, schools, and hospitals arrive that way. The first decision is a fax service with a BAA. The second, which matters more, is what happens to each referral after it lands. We make one of the products on this list, so here is the disclosure up front: Stable is included.
Short answer
HIPAA-compliant online fax options for therapists include eFax (BAA on Business, Corporate, and Unite plans, not Personal), Fax.Plus (BAA on its Enterprise plan), iFax and mFax (BAA available), Spruce (e-fax with an automatic BAA for eligible organizations), and RingCentral (BAA program). Check that the plan you buy includes the BAA. Then decide who reads each referral and reaches the patient the same day.
What to check
- The BAA is on your plan. Several services offer a BAA only on business or enterprise tiers.
- Faxes are stored encrypted, with access limited to named users.
- Audit trail, for who opened what.
- Retention, and deletion.
- What happens next. A fax service receives referrals. It doesn't read them or call the patient.

What to do with the referrals
A referral fax is a patient waiting. The usual path, someone downloads the PDF, types it into a spreadsheet, and calls the patient between sessions, loses many of them. Write down your acceptance criteria, aim to reach the patient the same day, and track every referral to a first appointment.
Where Stable fits
Stable's fax referral intake works with eFax: it reads each fax, extracts the patient's details, checks your acceptance rules, texts the patient to confirm interest, collects both sides of the insurance card, and runs a benefits check. Unclear documents go to a person. See referral management software compared.
