Pre natal expenses

I’m a Singapore Citizen and was told will be reimbursed back through Medisave. However, mine was given back to me via cash cheque as my hospital insurance covered ALL the expenses. I also had post-delivery complications so I had to be hospitalised for a week. My pre-natal expenses amounted up to $1177 and my total daily hospital stay was $900, all given cash cheque to me. Usually will be reimbursed to Medisave.
