MediSave cannot be used to pay for the cost of any disability assessments. 

However, all severe disability schemes (i.e. CareShield Life, MediSave Care, ElderShield, ElderFund and IDAPE) share the same disability assessment. If you are a CareShield Life policyholder and are undergoing a severe disability assessment for the first time, the cost of your first severe disability assessment by an MOH-accredited severe disability assessor will be waived. Otherwise severe disability assessments will be fully reimbursed if you are assessed to have developed severe disability. AIC will send you a letter to inform you about details of the reimbursement and the account to which the reimbursement will be made.
