What type of health insurance plan enables you to see any healthcare provider and reimburse you according to the pre-approved amount?

Many health cares allow you to do that. Or so they say, when you see commercials on T.V about how you can see any doctor or pharmacist, but when you apply for them you can't do that. There is no specific answer for this, just be careful on what you see on the internet or on the TV

Think it's rice because in many countries rice is the main food so it can be traditionally served all at once.
