MediSave and insurance for colorectal surgery in Singapore
By Dr Wong Nan-Yaw, MBBS (NUS), FRCS (Edinburgh). Published . 3 min read.
Dr Wong Nan-Yaw is an Alliance Medinet panel doctor. He can request pre-authorisation from insurers including Prudential and AIA before treatment, so you know the insurer's decision in advance, although it is not a guarantee of payment. Prudential patients can claim when he operates at Aptus Surgery (Paragon), a day surgery centre listed on Prudential's PRUPanel Connect. Integrated Shield Plans already include MediShield Life. Eligible remaining charges may be paid from MediSave within the limits for your procedure, and any uncovered balance is paid in cash (MOH, CPF).
What is pre-authorisation?
Pre-authorisation is a request sent to your insurer before treatment, asking it to confirm that the procedure is covered and how much it will pay. Dr Wong's clinic writes the request for you, and the insurer's decision is known before you go ahead.
What if my surgeon is not on my insurer's panel?
Not being on a panel does not stop you from claiming. If your plan has an extended panel, you can see doctors outside your insurer's panel. Dr Wong can request pre-authorisation from your insurer, including Prudential and AIA, and the clinic writes in to other insurers in the same way. The insurer decides, and the approved amount depends on your own policy.
How do MediSave and MediShield Life help?
MediSave can be used for approved surgical procedures and day surgery, up to the limit set for each procedure. MediShield Life covers claims for hospital and approved day surgery bills, subject to its terms. The clinic checks the limits for your procedure before treatment.
- MediSave withdrawal limits depend on the procedure code
- Insurance pays the amount your insurer approves under your policy
- Any remaining balance is settled from MediSave, MediShield Life claims or cash
