What Is an FMLA Certification Deficiency Notice?

A certification deficiency notice is the employer’s written communication telling the employee that the FMLA certification is incomplete, insufficient, or otherwise needs correction before the employer can make a final designation decision.

Incomplete

When Information Is Missing

An incomplete certification usually means one or more applicable entries on the form were not completed.

  • Blank required fields
  • Missing provider signature
  • Missing expected duration
  • Missing treatment schedule

Insufficient

When Information Is Unclear

  • Unclear frequency
  • Unclear duration
  • Vague medical necessity
  • Nonresponsive answers

What Should a Deficiency Notice Include?

A strong deficiency notice gives the employee clear, practical instructions for correcting the certification.

Issue

Identify the Problem

State whether the certification is incomplete, insufficient, or both. Avoid vague language that does not explain the problem.

  • Missing information
  • Unclear information
  • Nonresponsive answer
  • Specific form section or question
Instruction

Explain What Is Needed

Tell the employee exactly what additional information is necessary to make the certification complete and sufficient.

  • What must be completed
  • What must be clarified
  • Where to submit the correction
  • Who to contact with questions
Deadline

Provide a Cure Deadline

In most circumstances, the employee should be given 7 calendar days to provide the additional information.

  • Date deficiency notice was sent
  • 7-calendar-day cure deadline
  • Delivery method
  • Follow-up reminder

Certification Deficiency Workflow

Employers should follow a consistent process before denying or delaying FMLA protection based on certification problems.

Step 1

Receive Certification

Record the date the employee returned the certification and store it in the confidential leave file.

Step 2

Review for Completeness

Determine whether required entries are missing, blank, or not completed.

Step 3

Review for Sufficiency

Determine whether the completed information is clear, responsive, and supports the leave request.

Step 4

Send Written Notice

Explain the deficiency and what information must be corrected or clarified.

Step 5

Track Cure Period

Track the 7-calendar-day response window and document any employee follow-up.

Step 6

Make Designation Decision

After enough information is available, issue the appropriate Designation Notice.

FLARE™ Insight

A deficiency notice is not just a warning letter. It is a process control. It gives the employee a fair opportunity to correct the certification, gives HR a documented deadline, and gives the employer a cleaner path to the final Designation Notice. Without this step, employers often end up with inconsistent decisions, unclear leave status, and weak documentation.

Common Certification Deficiency Notice Mistakes

These are the mistakes employers should audit when reviewing FMLA certification follow-up.

Mistake 1

Using Generic Language

Telling an employee “your certification is deficient” is not enough. The notice should explain what is missing or unclear.

Mistake 2

No Cure Deadline

Employers should provide a clear deadline and track the 7-calendar-day cure period in most circumstances.

Mistake 3

Denying Too Quickly

Employers should generally provide written notice and an opportunity to cure before denying FMLA protection based on a deficiency.

Mistake 4

Requesting Unrelated Information

Employers should not ask for unrelated medical history or information outside the FMLA leave reason.

Mistake 5

No Proof of Delivery

Keep documentation showing when the deficiency notice was sent, how it was delivered, and what it said.

Mistake 6

Skipping the Designation Notice

After the certification issue is resolved or the cure period expires, employers still need a designation decision.
