Closing AE and carte carte vitale

Hi, hoping someone can help please. My OH needs to close his AE business (chambres d’hotes) so what will happen now with his carte vitale?
Does he have to make an application to Amelie?

He doesn’t have to do anything immediately because you are entitled to a certain period of residual cover under the existing arrangements after you close an ME - I think it’s 12 months although it could be 6, but google will be your friend if you desperately need to know.
Normally he will then receive a letter around a months before this period of grace expires, telling him the date on which his rights will end. At that point he will need to apply for healthcare via a different route.

When my OH closed her AE business, nothing changed with healthcare.

Thanks. That’s a huge relief!
