What Are FMLA Second and Third Medical Opinions?

Second and third medical opinions are employer-requested reviews used when there is a valid basis to question whether a medical certification supports FMLA leave.

Second Opinion

When the Employer Has Doubt

If the employer has reason to doubt the validity of a medical certification, the employer may require the employee to obtain a second opinion at the employer’s expense.

  • Reason to doubt validity
  • Employer pays for second opinion
  • Employer may select the provider
  • Employee remains provisionally entitled to FMLA benefits while pending
Third Opinion

When Opinions Conflict

If the employee’s provider and the employer’s second-opinion provider disagree, the employer may require a third opinion. The third opinion is final and binding.

  • Used when first and second opinions differ
  • Employer pays for third opinion
  • Provider must be jointly approved
  • Final and binding result

Employer Rules for Second Opinions

Employers should follow a careful process before requesting a second opinion.

Reason

Reason to Doubt Validity

The employer should document the specific reason it doubts the validity of the certification.

  • Certification conflicts with known facts
  • Medical support appears inconsistent
  • Pattern raises documented concerns
  • Issue is tied to certification validity
Provider

Provider Selection Limits

The employer may choose the second-opinion provider, but the provider generally cannot be employed by the employer on a regular basis or regularly used by the employer.

  • Independent provider
  • Appropriate specialty when possible
  • No regular employer relationship
  • Limited exception for areas with very limited access
Expense

Employer Pays Costs

The employer must pay for the second opinion and reimburse reasonable out-of-pocket travel expenses when required.

  • Second opinion cost
  • Reasonable travel costs
  • No unreasonable travel distance
  • Document reimbursement process

Second and Third Opinion Workflow

Employers should use a structured process before moving from initial certification to second or third opinions.

Step 1

Review Certification

Confirm the certification is complete and sufficient before considering a second opinion.

Step 2

Document Doubt

Document the specific reason the employer doubts the validity of the certification.

Step 3

Select Provider

Select an appropriate second-opinion provider who is not regularly employed or used by the employer.

Step 4

Notify Employee

Communicate the second-opinion requirement, scheduling process, and expense/reimbursement expectations.

Step 5

Compare Opinions

If the first and second opinions conflict, determine whether a third opinion is needed.

Step 6

Finalize Decision

Use the final opinion outcome to complete the FMLA designation or leave decision.

FLARE™ Insight

Second opinions are high-risk process moments. They should not be used as a shortcut when the real issue is an incomplete or insufficient certification. Before requesting a second opinion, employers should confirm whether the employee was given an opportunity to cure deficiencies and whether the concern is truly about certification validity.

Common Second and Third Opinion Mistakes

These are the mistakes employers should audit before requiring additional medical opinions.

Mistake 1

Using It for Deficient Certifications

Incomplete or insufficient certifications should usually be addressed through the deficiency cure process first.

Mistake 2

No Documented Reason for Doubt

Employers should document why they doubt the validity of the certification before requiring a second opinion.

Mistake 3

Using a Regular Employer Doctor

The second-opinion provider generally cannot be regularly employed or regularly used by the employer.

Mistake 4

Not Paying Required Costs

Employers must pay for second and third opinions and reimburse reasonable out-of-pocket travel expenses when required.

Mistake 5

Skipping Joint Approval for Third Opinion

The third-opinion provider must be jointly approved by the employer and employee.

Mistake 6

Forgetting Provisional FMLA Status

While the second or third opinion is pending, the employee is provisionally entitled to FMLA benefits.
