Hello Everybody

Due to a steep increase in prices for health insurance, I'm considering to change my current insurance provider (where I have had basic health insurance "traditionelle"). I would like to change to another provider and to the model of GP (as it seems to be much cheaper).

Now my question is the following: at this moment I am in a treatment which will last for another 6-7 months and even if I change to GP, I don't want to change my current specialist doctor who helps me with this treatment (I only want this GP to apply for next possible situations). Do you know if it is possible that the new provider won't cover my bills from that doctor, unless I change it (he's not a family doctor, he's a specialist doctor in a hospital)??

Thank you a lot for any advise.
