(b) A carrier that participated in the market on or after a date set by the commissioner by regulation may not withdraw from the market until all insureds of such carrier have had the opportunity to join a policy for medicare supplement insurance or medicare select insurance or a policy issued pursuant to a risk or cost contract offered by another carrier during the next annual open enrollment period or other enrollment period required in section three.
