The savings in your CPF accounts are for specific uses. Savings in your Ordinary Account and Special Account are primarily for housing and retirement, while savings in your MediSave are for the payment of selected healthcare insurance premiums (such as MediShield Life and CareShield Life premiums) and hospitalisation expenses.

Thus, you are unable to use the savings in your Ordinary Account and Special Account to pay for your CareShield Life premiums.
