Psycology:
If you have received a maximum of 2 treatments/interviews, we can send the payment guarantee to another therapist.
If you have received +2 treatments, contact your insurance company and talk to them about setting up a new payment guarantee for another therapist.
Physical treatment:
If you have received a maximum of 1 treatments/interviews, we can send the payment guarantee to another therapist.
If you have received +1 treatments, contact your insurance company and talk to them about setting up a new payment guarantee for another therapist.
In principle, it is always the therapist himself who requests more treatments, and thus not you.
However, there are exceptions depending on your policy, i.a. Health Care Guarantee or Chronic Disease. With these it is you who must contact your insurance company to get a new payment guarantee.
The terms for who should request are stated in the email you received when creating the case.
