If you have received a letter from the CAK
The letter you received from the CAK will say that you are ‘not insured’. This is because you do not have Dutch basic health insurance (basisverzekering) from a Dutch insurance provider.
If you are insured under the Dutch long-term care scheme (Wlz scheme), you are also insured under the Dutch basic health care scheme (Zvw scheme). Everyone who is insured under the Zvw scheme, is obliged to take out a basic insurance package (basisverzekering) with a Dutch health insurance provider.
