TPM links to the new policy guidance here. Under this new rule, insurers must send one of two different letters to customers.

Included with this guidance are standard notices that are required to be used in order to satisfy the requirement outlined above. Attachment 1 is the notice that must be sent to policyholders that have already been sent a cancellation notice for the existing coverage. Attachment 2 is the notice that must be sent to policyholders that have not previously been sent a cancellation notice for the existing coverage. The appropriate notice must be delivered to the policyholder separately from any other plan materials or correspondence.
