(a) A contract between an insurer and a group policyholder under a preferred provider benefit plan must provide that:
(1) in addition to any other premiums for which the group policyholder is liable, the group policyholder is liable for an individual insured’s premiums from the time the individual is no longer part of the group eligible for coverage under the policy until the end of the month in which the policyholder notifies the insurer that the individual is no longer part of the group eligible for coverage under the policy; and
(2) the individual remains covered under the policy until the end of that period.
(b) Each insurer that enters into a contract described by Subsection (a) shall notify the group policyholder periodically as provided by this section that the policyholder is liable for premiums on an individual who is no longer part of the group eligible for coverage until the insurer receives notification of termination of the individual’s eligibility for coverage.

(c) If the insurer charges the group policyholder on a monthly basis for the premiums, the insurer shall include the notice required by Subsection (b) in each monthly statement sent to the group policyholder. If the insurer charges the group policyholder on other than a monthly basis for the premiums, the insurer shall notify the group policyholder periodically in the manner prescribed by the commissioner by rule.
(d) The notice required by Subsection (b) must include a description of methods preferred by the insurer for notification by a group policyholder of an individual’s termination from coverage eligibility.
