How FMLA Recertification Works: Frequency, Deadlines, and Costs

Under the Family and Medical Leave Act, recertification is the process your employer uses to confirm you still need FMLA leave for an ongoing serious health condition. The federal rule sets a clear ceiling: no more than once every 30 days, and only in connection with an actual absence.¹ You get at least 15 calendar days to return the paperwork, you pay for it, and missing the deadline can strip FMLA protection from the absences that follow.

How Often Your Employer Can Ask

The baseline is every 30 days, and the request has to be tied to an actual absence. An employer cannot send a recertification form to someone who has not taken recent leave.¹

If your original certification stated a minimum duration longer than 30 days, the employer has to wait out that period. A certification that covers 40 days of leave, for instance, blocks a recertification request on day 31. There is one hard ceiling on the other side: no matter what the certification says about how long your condition will last, the employer can always request recertification every six months in connection with an absence. That matters most for chronic or lifetime conditions where the initial paperwork projects years of intermittent leave.¹

When Employers Can Ask Sooner Than 30 Days

Three specific circumstances let an employer bypass the waiting period:

You request more FMLA leave than the original certification covered.
The circumstances described in the certification have changed significantly. If the certification predicted one- or two-day migraine absences but your last two episodes each ran four days, that increased duration counts. So does an absence pattern that consistently lands right before or after scheduled days off.
The employer receives information that casts doubt on your stated reason for the absence. The regulations offer the illustration of an employee on four weeks of leave for knee surgery who turns up playing in a company softball league in week three.¹

A vague hunch is not enough. The employer still needs an articulable reason falling within one of those three categories.

Your Deadline, Your Cost

Once the request is made, you have at least 15 calendar days to return a completed recertification unless it is genuinely not practicable despite your best efforts.¹ “Not practicable” covers real obstacles, like a medical emergency or a documented booking delay at your provider’s office when you have been diligent about scheduling. Ordinary inconvenience does not qualify.

The bill is yours. Any recertification the employer requests is at the employee’s expense unless the employer agrees otherwise.¹ Doctors’ offices commonly charge a paperwork fee for completing the forms, and that is yours to pay.

Unlike the initial certification, the recertification request itself does not have to be in writing. An oral request is sufficient, though most employers put it in writing anyway to fix the date the clock started. The employer still has to tell you what happens if you fail to provide adequate documentation.²

The Department of Labor’s optional forms are WH-380-E for your own serious health condition and WH-380-F for a family member’s. Employers can use those or their own version, as long as it asks only for information the FMLA allows. Your employer also has to accept a complete and sufficient certification even if it arrives on the provider’s letterhead or by fax rather than on the company template.³

What the Form Can Ask

Recertification can request the same categories of information as the initial certification under 29 CFR 825.306:¹

The healthcare provider’s identifying information and specialization.
The approximate start date of the serious health condition and its probable duration.
Medical facts supporting the continued need for leave, such as symptoms, diagnosis, prescribed medication, or ongoing treatment.
For your own condition, whether you remain unable to perform essential job functions.
For a family member’s condition, an estimate of the frequency and length of absences needed to provide care.
For intermittent leave, the medical necessity and the estimated frequency and duration of episodes.⁴

Recertification carries one extra tool the employer can use on intermittent leave. The employer may share a record of your actual absence pattern with the provider and ask whether the serious health condition and the need for leave are consistent with that pattern.¹ It forces the provider to line up the medical picture with how leave is actually being taken.

What the employer cannot do at recertification is send you for a second or third medical opinion.¹ That right exists for the initial certification but not for recertification. Your provider’s word stands.

If the Form Comes Back Incomplete

Suppose you send in the recertification but entries are blank or answers are ambiguous. The employer has to tell you in writing what is wrong and give you at least seven calendar days to fix it. Only after that cure period expires can the employer deny FMLA leave based on the deficiency.²

An incomplete recertification is not the same as no recertification at all. A form with gaps triggers the cure process. A total failure to return any paperwork does not; that is treated as failure to provide certification.

What Happens If You Miss the Deadline

If you fail to provide recertification within a reasonable time given the circumstances, the employer may deny continuation of FMLA protection until you produce a sufficient recertification. Absences that fall in the gap are not FMLA-protected and can be counted against you under the employer’s regular attendance policy.⁵

If you never produce it, the leave is not FMLA leave at all, and the employer can apply its standard discipline for unexcused absences up to and including termination.⁵ Submitting the paperwork later does not retroactively protect the absences that already happened.

The regulation does build in room for genuine hardship. The standard is whether you provided the recertification as soon as practicable under the particular facts and made diligent, good-faith efforts. A medical emergency that keeps you from a scheduled appointment is the kind of situation where the deadline flexes. Putting off the appointment is not.

When It’s a New Certification, Not a Recertification

When the same medical condition carries into a new 12-month FMLA leave year, the employer can require an entirely new medical certification rather than a recertification.⁶ That distinction has bite. A new certification is subject to the full initial-certification rules, including the employer’s right to require a second and, if needed, a binding third medical opinion at the employer’s expense. Those rights disappear during mid-year recertification.

If you have a chronic condition and take FMLA leave year after year, expect a fresh certification each time your leave year resets, not a simple recertification.

What Recertification Does Not Cover

The recertification rules apply only to leave for a serious health condition, yours or a family member’s. They do not apply to qualifying exigency leave tied to a family member’s military service, or to leave to care for a covered servicemember with a serious injury or illness. Those categories have their own certification procedures under different sections of the regulations.⁵

Also worth separating: an employer can require periodic status reports on your intent to return to work while you are on leave.⁷ That is a simple check-in, not a medical recertification, and it does not carry the 30-day rule or the 15-day response deadline. If you get a request that only asks about your return plans, that is a status report, not a recertification.
