Section 509B.5 - Notice of termination of membership or modification of coverage1. Employers or group policyholders shall notify all employees or members of their continuation rights within ten days of termination of employment or membership. The notice shall be in writing and delivered in person or mailed to the person's last known address. However, continuation rights shall not be denied because of failure to provide proper notice. After receiving proper notice the employee or member may request and shall receive continuation coverage in accordance with this chapter within ten days of the request, notwithstanding any other time limitation provided by this chapter. Notification as provided in this section supersedes section 515.125 as that section relates to accident and health insurance.2. If an employer or group policyholder terminates or substantially modifies an agreement to provide accident or health insurance for employees or members or if accident or health insurance for employees or members is terminated for failure to pay premiums or for another reason, the employer or group policyholder shall notify the employees or members, including persons being continued under the policy's continuation provisions, of the termination or substantial modification of their coverage. The notice shall be in writing and delivered in person to the entitled persons or mailed to their last known addresses at least ten days prior to the termination or substantial modification of the accident or health insurance coverage. The employer or group policyholder is solely liable for benefits, including extended benefits, other than extended benefits for which the insurer is liable in accordance with the provisions of the group policy, which would have been payable had the accident or health insurance remained in force or not been terminated or substantially modified during the period of time following the termination or substantial modification until the person entitled to notice is given notice by the employer or group policyholder as required by this subsection.3. The employer or group policyholder is also solely liable for benefits, including extended benefits, which would have been payable had the accident or health insurance been in force and the employees or members been covered during the period of time the employer or group policyholder failed to implement the plan for accident or health insurance which the employer or group policyholder had agreed to provide, until the employer or group policyholder gives notice of its failure or inability to provide the agreed plan. The notice shall be in writing and delivered in person to the employees or members or mailed to their last known addresses.4. The employer or group policyholder is also solely liable for benefits, including extended benefits, which would have been payable had the accident or health insurance been in force and the employees or members been covered by the accident or health insurance during a period of time for which the employer or group policyholder has collected contributions through payroll, withholding, or otherwise, but has failed to enroll the employees or members, unless the employer or group policyholder has given actual notice that enrollment in the plan will not become effective until a later date or until the employee's or member's application for enrollment has been approved.
