Automatically upon purchase
When you pay for your medication over the counter, the pharmacy sees in your file that you are insured and automatically calculates the amount paid by the insurer, and the balance you must pay.
After the purchase without procedure
You pay for your medication out of pocket at the counter and receive a reimbursement from your insurer without having to do anything. Everything is done automatically.
After purchase with procedure
You pay for your medication in out of pocket at the counter. You must notify your insurer and provide proof of purchase. Reimbursement will then be initiated by the insurer.
