Yes, you can fax protected health information (PHI) under HIPAA, but only with the right safeguards in place. The core focus of HIPAA standards is protecting PHI regardless of the technology used to transmit it. It could be fax or other document exchange methods.
Healthcare faxing remains common for sending and receiving patient referrals, intake forms, and other sensitive documents. This guide explains what HIPAA-compliant faxing involves, the key requirements, and how to choose a trusted healthcare fax service that makes compliance easier to maintain.

Key takeaways
- HIPAA permits faxing PHI for permitted purposes with reasonable safeguards. It does not specifically “approve” fax machines or software.
- Online fax can establish safeguards through encryption, access controls, audit logs, and a signed business associate agreement (BAA).
- No tool guarantees compliance on its own. Policies, training, and risk analysis still matter.
What Is HIPAA-Compliant Fax?
HIPAA-compliant faxing is the sending and receiving of PHI via fax, using the administrative, physical, and technical safeguards required by the HIPAA Privacy and Security Rules. In practice, this usually means faxing with access controls, encryption, and audit logs, using a provider that has signed a BAA, backed by written policies and staff training.
This process applies to covered entities and business associates, such as hospitals, clinics, labs, pharmacies, and the vendors that handle PHI for them. Also, it can use a fax machine or an online fax service.
With online fax, the safeguards are easier to apply and prove, because every activity is logged and access is controlled.

Is a Fax HIPAA Compliant?
Short answer: A fax isn’t compliant or non-compliant on its own. HIPAA permits faxing PHI when the sender has a lawful purpose and applies reasonable administrative, physical, and technical safeguards.
According to HHS, the Privacy Rule permits covered entities (e.g., hospitals) to share PHI for treatment without patient authorization, provided they use reasonable safeguards.
The HHS offers a practical example: when faxing to a number that isn’t regularly used, a reasonable safeguard is to confirm the number with the intended recipient first.
How you fax changes how easy those safeguards are to apply:
Traditional fax machine | Online (cloud) fax | |
Exposure | Printed pages can sit in shared trays | Faxes arrive in a secured, access-controlled account |
Misdirected faxes | Manual dialing; insufficient record beyond a confirmation sheet | Saved contacts reduce keying errors; delivery records are kept |
Audit trail | Usually none | Activity logs show who sent or viewed what, and when |
Vendor agreement | Usually not applicable | Providers are required to sign a BAA |
Note: There is no government certification for fax software. Compliance depends on how your organization and your vendor operate, so “HIPAA compliant fax” describes the process instead of a product.
How to Get a HIPAA-Compliant Fax
First, choose a provider that signs a BAA and offers advanced encryption, role-based access, and audit trails or transaction logs. Support it with written policies and staff training.
General steps to follow:
- Choose a fax provider that will sign a BAA. If a vendor won’t sign one, don’t use it for PHI. iFax offers free BAA signing.
- Check the technical safeguards. Look for encryption in transit and at rest, user authentication, and activity logs with fax delivery confirmations.
- Set up access by teams or role. Give each user only the fax access their job requires, and use a shared team inbox instead of a shared machine tray.
- Document your fax policy and train staff. Cover number verification, cover sheet use, and what to do when a fax is misdirected.
- Test, review, and keep records. Run a trial fax, include faxing in your regular risk analysis, and confirm retention rules with your compliance officer.
HIPAA Fax Requirements: What the Rules Say
Three HIPAA rules shape how organizations handle faxed PHI:
- Privacy Rule: Governs when PHI can be used and disclosed, including the minimum necessary standard. Disclosures for treatment between providers are exempt from that standard.
- Security Rule: Governs how electronic PHI is protected, which applies to online fax systems.
- Breach Notification Rule: Governs what to do when PHI is exposed.

A Note on HIPAA Fax Policy
While HIPAA doesn’t provide a standard fax policy, it does require covered entities and their business associates to maintain written policies and procedures. A HIPAA policy also applies those requirements to faxed PHI.
A strong policy generally covers:
- Permitted Uses: Which documents and purposes are allowed, following the minimum necessary standard where it applies.
- Sending Safeguards: Confirming recipient names and fax numbers, and using a HIPAA fax cover sheet with no PHI.
- Access and Vendor Controls: Set role-based permissions, secured inboxes, and a signed BAA with any online fax provider
- Incident Response: Set guidelines for reporting and assessing a misdirected fax.
- Retention and Review: Define how long fax records are kept and how they are securely disposed of. Schedule regular policy reviews and updates.
Have your compliance officer or legal counsel confirm that your fax policy meets your organization’s requirements before it is implemented.
Regulatory watch
HHS proposed a major Security Rule update in January 2025 that would turn encryption, currently an addressable specification, into a required safeguard. Final action has reportedly been pushed to at least July 2027, and the current rule remains in force in the meantime. Treat strong encryption as the baseline now.
Best Practices for HIPAA-Compliant Faxing
Always verify before you send
Confirm each recipient and fax number, especially numbers you rarely use. Send only the pages needed. Never leave documents unattended at a machine, and lock your computer or phone screen when you step away from an online fax session.
Use a HIPAA fax cover sheet
Include sender and recipient details, page count, and a confidentiality notice. Keep patient information off the cover sheet. HIPAA doesn’t mandate a specific disclaimer, but one helps a misdirected recipient know what to do. A cover sheet helps reduce risk in addition to other safeguards.
Our fax cover sheets for HIPAA-compliant faxing are a good starting point.
Require a signed BAA before using a fax service for PHI
A cloud fax provider that stores or processes PHI acts as a business associate, so you need a legally signed BAA that defines permitted uses, safeguards, and breach reporting. If a provider won’t sign one, don’t use it for PHI.
See our BAA template for what to expect.
Keep audit trails
Audit controls are part of the HIPAA Security Rule’s technical safeguards. They require mechanisms to log, monitor, and audit fax activity that contains or uses electronic protected health information. Fax logs that show who sent, received, accessed, or opened a fax, and when those events occurred, can support investigations, security reviews, and required activity reviews.
As part of HIPAA requirements, covered entities and business associates must retain required Security Rule documentation for at least six years. Whether a particular fax log is treated as required documentation depends on the organization’s policies, its use of the log for compliance evidence, and other applicable legal or contractual requirements. Confirm the retention period with your compliance officer.
Limit exposure to the minimum necessary
When faxing, share only what the recipient needs, grant staff access by role, and train them on what to do if a fax is misdirected. Keep PHI off portable devices unless they’re encrypted, and review your risk analysis regularly.
Common mistakes to avoid ❌:
- Dialing the wrong fax number
- Faxing without a cover sheet
- Leaving an inbox unsecured
- Using a fax service to fax PHI without a BAA
- Having no written policies and procedures
