You will not be able to be on both CareShield Life and ElderShield.
However, upgrading to CareShield Life will not affect your ElderShield Supplement plan if you already have one. If you are currently covered under ElderShield, you can upgrade to CareShield Life for higher and lifetime payouts. Your ElderShield coverage will be terminated upon joining CareShield Life. For more coverage, you can also purchase Supplement plans from private insurers.
