29 CFR § 825.212 - Employee failure to pay health plan premium payments.
(1) In the absence of an established employer policy providing a longer grace period, an employer's obligations to maintain health insurance coverage cease under FMLA if an employee's premium payment is more than 30 days late. In order to drop the coverage for an employee whose premium payment is late, the employer must provide written notice to the employee that the payment has not been received. Such notice must be mailed to the employee at least 15 days before coverage is to cease, advising that coverage will be dropped on a specified date at least 15 days after the date of the letter unless the payment has been received by that date. If the employer has established policies regarding other forms of unpaid leave that provide for the employer to cease coverage retroactively to the date the unpaid premium payment was due, the employer may drop the employee from coverage retroactively in accordance with that policy, provided the 15-day notice was given. In the absence of such a policy, coverage for the employee may be terminated at the end of the 30-day grace period, where the required 15-day notice has been provided.
(b) The employer may recover the employee's share of any premium payments missed by the employee for any FMLA leave period during which the employer maintains health coverage by paying the employee's share after the premium payment is missed.
(c) If coverage lapses because an employee has not made required premium payments, upon the employee's return from FMLA leave the employer must still restore the employee to coverage/benefits equivalent to those the employee would have had if leave had not been taken and the premium payment(s) had not been missed, including family or dependent coverage. See § 825.215(d)(1)-(5). In such case, an employee may not be required to meet any qualification requirements imposed by the plan, including any new preexisting condition waiting period, to wait for an open season, or to pass a medical examination to obtain reinstatement of coverage. If an employer terminates an employee's insurance in accordance with this section and fails to restore the employee's health insurance as required by this section upon the employee's return, the employer may be liable for benefits lost by reason of the violation, for other actual monetary losses sustained as a direct result of the violation, and for appropriate equitable relief tailored to the harm suffered.
