Is a healthcard valid after ARC renewal but before new healthcard arrives?

What is likely to happen if you have a medical appointment scheduled for a week after your ARC renewal comes through? My understanding is that after an ARC renewal you need to apply for a new NHI card and that takes about 10days to process.

Is it possible to use your previous NHI card since the ARC is valid? Do you just get charged the uninsured rate and have to file for reimbursement after?

Any info would be appreciated!

You don’t need to renew your health insurance card…use away.

When that’s the case ever, yes you need to pay the full rate and get your money back later.
I’ve had it happen twice.
