Healthcare & HIPAA Faxing

Do you have a solution that’s compliant with applicable security and privacy standards such as HIPAA?

Yes, eFax Secure™, part of eFax Corporate’s business cloud fax solutions is our HIPAA compliant fax solution, which uses strong encryption for the protection of ePHI through a secure portal and in-transit to Business Associates you work with – who receive an email with a secure link to the ePHI. This is one of the reasons that eFax Corporate is the fax service of choice for businesses in the most heavily regulated industries — such as healthcare, financial services, legal and real estate.

Does the HIPAA Security Rule allow for sending electronic PHI (e-PHI) in an email or over the Internet? If so, what protections must be applied?

The HIPAA Security Rule does not expressly prohibit the use of email for sending e-PHI. However, the standards for access control (45 CFR § 164.312(a)), integrity (45 CFR § 164.312(c)(1)), and transmission security (45 CFR § 164.312(e)(1)) require covered entities to implement policies and procedures to restrict access to, protect the integrity of, and guard against unauthorized access to e-PHI. The standard for transmission security (§ 164.312(e)) also includes addressable specifications for integrity controls and encryption. This means that the covered entity must assess its use of open networks, identify the available and appropriate means to protect e-PHI as it is transmitted, select a solution, and document the decision.

Does your solution provide send and receive encryption? If yes, please describe the encryption process.

Yes, eFax Corporate’s cloud fax solutions can enable the highest levels of encryption for both your inbound and outbound faxes. For sending and receiving secure faxes over eFax Corporate’s secure network, our solution can enable on the most sophisticated encryption standard, TLS 1.2 (Transport Layer Security). eFax Secure™ is available to customers who want secure storage of all inbound faxes on the cloud – accessible 24/7/365 via a secure portal.

Do you have an API solution that can enable a secure fax from our EHR System?

Yes, eFax Corporate’s offers custom fax API integration through our eFax Developer API. This allows businesses to connect cloud faxing directly to their existing workflow platforms and productivity tools — including CRM or ERP systems such as Salesforce, Sage, Netsuite; or in the case of healthcare firms, Electronic Healthcare Records systems such as NextGen, MediTouch, or Cerner via a simple to plug-in XML API. TLS can be enabled for the highest levels of encryption. All of these API options let businesses more easily and efficiently manage their electronic faxing, by allowing them to generate and send their faxes directly from the productivity platforms and applications they use every day.

Does eFax Corporate have in-bound/out-bound fax capabilities?

Yes, the eFax Corporate online fax service allows businesses to both send and receive faxes digitally, either by email or through a simple, secure web interface. Enterprises can also easily and securely send and receive faxes directly from mobile devices, including smart phones and tablets.

Technical Questions

Does your business fax service offer an auto re-send option?

Yes, and this is one of the many productivity increasing benefits of the eFax Corporate business fax services— no more having to stand at a fax machine to redial a busy fax number.
With eFax Corporate, your staff can send a digital fax, either by email or through their secure eFax Corporate web interface, and if the recipient’s fax number is busy, the system will automatically re-send the fax.
Our standard system will set up your internet faxing solution to retry a busy fax number five times, spaced over increasing delays among each re-dial attempt. In the case of a “human-answered” error — meaning an instance where the fax number was actually also a phone line and answered by a person or voicemail — we will attempt just a single re-send.
eFax Corporate can also tailor any of these specifications from our standard setup, to meet any enterprise’s needs.

Is international faxing available?

Yes. eFax Corporate customers can send digital faxes through the cloud to dozens of countries all over the world.
Please contact sales for send rates for international faxes sent through eFax Corporate.

Admins can log in to My Account anytime to add new virtual fax numbers as needed, assign new users, and review reports of inbound and outbound fax traffic — by individual employee or fax number, by department, or company wide.

From their My Account online portal, admins can also access a wealth of information to learn about how best to use their eFax Corporate service — such as learning how to set up business fax numbers, download APIs, and gain a better understanding of HIPAA fax compliance.
