Frequently Asked Questions
What is a HIPAA-compliant phone and fax service?
A HIPAA-compliant phone and fax service is any communication platform that signs a Business Associate Agreement (BAA), encrypts PHI in transit and at rest (AES-256 / TLS 1.2+), maintains audit logs, and enforces role-based access controls — satisfying the HIPAA Security Rule for covered entities and business associates.
Do I need a BAA for my fax service?
Yes. Any third-party vendor that transmits, stores, or accesses Protected Health Information (PHI) on your behalf is a Business Associate under HIPAA. You must sign a BAA before sending the first patient fax. Using a fax service without a BAA is a federal violation and can trigger fines starting at $141 per incident.
Can I use a regular phone line for HIPAA-compliant faxing?
Traditional analog fax over PSTN phone lines is technically outside the HIPAA Security Rule's electronic safeguard requirements, but you still need physical controls (secure placement, access restrictions) and administrative safeguards (cover sheets, misdirected fax procedures). For full compliance and a BAA, online fax services are the modern standard.
What is the cheapest HIPAA-compliant fax option?
mFax Business starts at $20.99/month and includes HIPAA-ready encryption, virtual fax numbers, and the ability to sign a BAA. It is one of the most affordable options for small healthcare practices. See our [full comparison of HIPAA-compliant fax services](/blog/best-hipaa-compliant-fax-services/).
What happens if I send a fax with PHI without HIPAA safeguards?
A misdirected fax containing PHI is a potential HIPAA breach. You must report it to your privacy officer, document the incident, and follow your breach notification procedures. Penalties range from $141 per violation for unknowing infractions up to $2.1 million per violation category for willful neglect.
