A country of residence package is a package of healthcare facilities and services your family members are entitled to in their country of residence. By healthcare services, we mean, for example, costs of the general practicioner, medicines and hospitalisations. Each country has a different country of residence package.
The coverage of the country of residence package is the same as the statutory healthcare package in that country. In the Netherlands, for example, this is the basic health insurance. Your family members are therefore entitled to reimbursement of the same healthcare as other residents of that country. They also have the same duties: if your country of residence has an own risk or contribution, the same applies to them.
