Starting from this year, Medisave withdrawal limits has been increased to $700 (per patient per year) for patients with:
1. at least 2 chronic conditions, or
2. 1 chronic condition with complications.

Patients with 1 chronic condition can use up to $500 per person per year, $200 lower than the abovementioned group.

To illustrate, if you have only 1 chronic condition and has already deducted $400 from your medisave account, you can only use $100 ($500 – $400) of your family members’ medisave accounts to pay for your future chronic medications. Nevertheless if you are a Singaporean aged 60 years and above, you can use your flexi medisave (cap $200 per year) to pay for the remaining bill.
