Yes. Based on CPF guidelines, Outpatient MediSave of up to $300 per patient per year (subjected to available MediSave balance), can be used for payment of your MRI scan. If you have previously authorised Medisave deductions via the Medical Claims Authorisation Form – Multiple or Single (MCAF(M) and/or MCAF(S)), up to $300 will be automatically deducted from your MediSave account as payment for your outpatient scan.
