How to Fax FMLA Form WH-380-E — Medical Certification for Leave
Form WH-380-E is the U.S. Department of Labor's certification for a serious health condition of an employee, completed by the treating health care provider to support a request for leave under the Family and Medical Leave Act. Employers and their leave administrators typically ask that the completed certification be returned by fax so the provider's section reaches the right office by the deadline. A faxed certification arrives as one document tied to the employee's leave request.
Why this form is faxed
FMLA gives an employee a limited window to return a complete certification, and faxing puts the provider-completed form in front of the employer's leave administrator without the delay of mail. Because the form describes a medical condition, sending it through a channel that records the transmission is a controlled way to meet the certification deadline and document that it was submitted.
Where it goes
The completed certification goes to the office the employer designates to receive FMLA paperwork — often a human-resources or third-party leave administrator, not a supervisor — and the correct fax number is the one that office provides with the leave request. Confirm the destination with HR or the leave administrator rather than sending it to a general company number, since medical certifications are meant to reach a limited, designated recipient.

Handling sensitive information
Form WH-380-E contains details of an employee's serious health condition, and the FMLA regulations require employers to keep medical certifications confidential and separate from the personnel file. Send it only to the designated leave-administration number you have confirmed; routing it to a supervisor or a general line can expose protected medical information the rules are meant to restrict.

Recent updates
Federal interoperability rules keep pushing healthcare past the fax machine
CMS has advanced a series of interoperability rules that press hospitals, payers, and providers toward electronic data exchange and standardized claims attachments. The direction of travel is clear: paper and analog fax workflows are being replaced by digital transmission that carries an auditable record — which is exactly what a cloud fax with delivery confirmation provides for offices not yet on a full EHR pipeline.
CMS →Federal agencies still write fax into new rules and notices
The Federal Register — the daily journal of U.S. federal rulemaking — regularly publishes rules and notices that reference fax as an accepted or required submission channel for filings with agencies like the IRS, SSA, and CMS. That is why fax remains a live requirement for many official forms even as electronic portals expand.
Federal Register →Healthcare breach reporting keeps document handling under scrutiny
Ongoing reporting on HIPAA breaches and OCR settlements underscores how much scrutiny falls on how medical documents are stored, sent, and received. Sending records through a controlled, access-logged channel rather than an unmanaged machine reduces the mishandling risks that show up repeatedly in breach analyses.

Faxing FMLA Medical Certification (Form WH-380-E) — FAQ
The employee's treating health care provider completes the sections describing the serious health condition and the expected duration or schedule of leave, since the certification rests on their clinical judgment. The employee provides their own identifying information, but the medical sections must come from the provider for the employer to accept the form.
FMLA regulations require that medical certifications be kept confidential and handled by a designated office, typically HR or a leave administrator, and stored separately from the regular personnel file. Confirm the number your employer designates for FMLA paperwork so the certification reaches the right recipient rather than a supervisor.
Under the FMLA rules an employer must give the employee a chance to cure a certification that is incomplete or insufficient, usually a set number of days, before leave can be denied. Confirming the provider filled in every required medical section before you fax it avoids losing days to a correction request against a deadline.
Send FAX Mail returns a confirmation showing the date and time the certification reached the destination line. Keeping that record lets you show your employer or leave administrator that the completed form was submitted within the certification window if the timing is ever questioned.
