What may an employer do if it questions the adequacy of a medical certificate for leave taken because of an employee’s own serious health condition or the serious health condition of a family member?

(See 29 CFR § 825.307) (a) If an employee submits a complete certification signed by the health care provider, the employer may not request additional information from the employee's health care provider. However, a health care provider representing the employer may contact the employee's health care provider, with the employee's permission, for purposes of clarification and authenticity of the medical certification. (1) If an employee is on FMLA leave running concurrently with a workers' compensation absence, and the provisions of the workers' compensation statute permit the employer or the employer's representative to have direct contact with the employee's workers' compensation health care provider, the employer may follow the workers' compensation provisions. (2) An employer who has reason to doubt the validity of a medical certification may require the employee to obtain a second opinion at the employer's expense. Pending receipt of the second (or third) medical opinion, the employee is provisionally entitled to the benefits of the Act. If the certifications do not ultimately establish the employee's entitlement to FMLA leave, the leave shall not be designated as FMLA leave and may be treated as paid or unpaid leave under the employer's established leave policies. The employer is permitted to designate the health care provider to furnish the second opinion, but the selected health care provider may not be employed on a regular basis by the employer. See also subsections (e) and (f) of this section. (b) The employer may not regularly contract with or otherwise regularly utilize the services of the health care provider furnishing the second opinion unless the employer is located in an area where access to health care is extremely limited (e.g., a rural area where no more than one or two doctors practice in the relevant specialty in the vicinity). (c) If the opinions of the employee's and the employer's designated health care providers differ, the employer may require the employee to obtain certification from a third health care provider, again at the employer's expense. This third opinion shall be final and binding. The third health care provider shall be designated or approved jointly by the employer and the employee. The employer and the employee shall each act in good faith to attempt to reach agreement on whom to select for the third opinion provider. If the employer does not attempt in good faith to reach agreement, the employer shall be bound by the first certification. If the employee does not attempt in good faith to reach agreement, the employee shall be bound by the second certification. For example, an employee who refuses to agree to see a doctor in the specialty in question may be failing to act in good faith. On the other hand, an employer that refuses to agree to any doctor on a list of specialists in the appropriate field provided by the employee and whom the employee has not previously consulted may be failing to act in good faith. (d) The employer shall provide the employee with a copy of the second and third medical opinions, where applicable, upon request by the employee. Requested copies are to be provided within two business days unless extenuating circumstances prevent such action. (e) If the employer requires the employee to obtain either a second or third opinion the employer shall reimburse an employee or family member for any reasonable "out of pocket" travel expenses incurred to obtain the second and third medical opinions. The employer may not require the employee or family member to travel outside normal commuting distance for purposes of obtaining the second or third medical opinions except in very unusual circumstances. (f) In circumstances when the employee or a family member is visiting in another country, or a family member resides in another country, and a serious health condition develops, the employer shall accept a medical certification as well as second and third opinions from a health care provider who practices in that country.
