FMLA Incomplete Medical Certification for Employers
A practical employer guide to incomplete FMLA medical certifications, including what incomplete means, how it differs from insufficient certification, what employers should tell employees, and how to track the 7-day cure period.
Incomplete Certification Quick Facts
Use this section as a quick employer reference before reviewing the full incomplete certification process.
What Is an Incomplete FMLA Certification?
An FMLA certification is incomplete when one or more applicable entries on the certification form have not been completed.
What Incomplete Means
Incomplete certification usually means a required part of the form was left blank or the employee did not provide information needed to evaluate the FMLA request.
- Missing provider information
- Missing treatment dates
- Missing expected duration
- Missing intermittent leave frequency or duration
How It Differs From Insufficient
Insufficient certification usually means the form was completed, but the information provided is vague, unclear, or nonresponsive.
- Vague responses
- Unclear frequency or duration
- Nonresponsive answers
- Information that does not support the leave request
What Should Employers Do When Certification Is Incomplete?
Employers should use a consistent process that gives the employee clear written instructions and a trackable deadline.
Review the Certification
Identify whether the issue is missing information, unclear information, or information outside the FMLA request.
Identify What Is Missing
List the specific entries or fields that must be completed so the employee knows what needs to be corrected.
Send Written Notice
Provide written notice explaining that the certification is incomplete and what additional information is needed.
Give Time to Cure
In most circumstances, give the employee 7 calendar days to provide the missing or corrected information.
Review the Response
Review the corrected certification to determine whether it is now complete and sufficient.
Send Designation Notice
Once enough information is available, send the FMLA Designation Notice approving, denying, or pending the request.
What Should the Incomplete Certification Notice Include?
The notice should be specific enough for the employee to understand exactly what must be corrected.
Specific Missing Information
Do not simply say the form is incomplete. Identify the specific fields, dates, or entries that were not completed.
- Missing provider signature
- Missing treatment schedule
- Missing expected leave duration
- Missing frequency or duration of intermittent leave
Clear Cure Deadline
The employee should receive a clear deadline to return the corrected certification.
- Date notice was sent
- 7-calendar-day cure deadline
- Where to return information
- Who to contact with questions
Consequence of Not Curing
The notice should explain that failure to provide complete and sufficient certification may affect FMLA protection.
- Leave may remain pending
- FMLA protection may be delayed or denied
- Attendance rules may apply
- Additional leave review may be needed
FLARE™ Insight
Incomplete certifications are not just paperwork problems. They are workflow problems. Employers need a consistent process for identifying missing information, sending written deficiency notices, tracking the 7-day cure period, documenting follow-up, and connecting the final certification review to the Designation Notice.
Common Incomplete Certification Mistakes
These are the mistakes employers should audit when reviewing incomplete FMLA certifications.
Denying Too Quickly
Employers should generally provide written notice and an opportunity to cure before denying FMLA protection based on incomplete certification.
Using Vague Follow-Up
A notice that says “your certification is incomplete” is not enough. The employee needs to know what specific information is missing.
Missing the Cure Deadline
Employers should track when the follow-up notice was sent and when the 7-calendar-day cure period expires.
Asking for Unrelated Information
Employers should only ask for information needed to support the FMLA reason, not unrelated medical details.
No Proof of Delivery
Employers should keep documentation showing when the incomplete certification notice was sent and how it was delivered.
No Final Designation
After the cure period and certification review, employers still need to send the appropriate Designation Notice.
