If your redeemed premium discounts have already been used for your MediShield Life (MSHL) premiums before you switched Integrated Shield Plan (IP), no further action would be required. Any unused premium discounts or premium discounts redeemed after you switched IP, will be carried forward and used for your MSHL premiums at your next policy renewal, so long as they remain valid (premium discounts are valid for one year from the date of redemption).
