Border workers

Making your sample when you are a frontier worker


What is a cross-border worker?

"Under Community rules, the term "frontier worker" means any worker who is employed in the territory of a Member State and resides in the territory of another Member State (political criterion), to which he returns in principle every day or at least once a week (temporary criterion).
European Parliament definition.

In 2022, 46.8% of workers in Luxembourg are frontier workers. To make life easier for frontier workers, Luxembourg offers many advantages, particularly in the field of health.

What are the rights of cross-border workers?

Cross-border workers enjoy the same health care benefits as Luxembourg residents. However, in order to benefit from these advantages, a prescription issued by a foreign or Luxembourg doctor is required. Medical tests that are covered by the CNS do not require an advance payment. If you have supplementary health insurance, certain tests not covered by the CNS may also be reimbursed without advance payment. If you do not have supplementary health insurance, it is important to note that the rate of reimbursement for most tests is generally higher in Luxembourg than in France, ranging from 80% to 100% depending on the services.

And for the family?

The frontier worker is obliged to report any family changes to the CNS, just as he or she would do in his or her country of residence. This means that family members can also benefit from health insurance in Luxembourg as co-insured. The designation of family members eligible for such co-insurance is determined by the legislation of the country of residence with regard to the affiliation of family members to the principal insured.

Going to a laboratory

Most of our nurses are fluent in French, English and German, and are able to answer all your questions about taking samples and the administrative details involved. In addition, our centres are evenly distributed throughout the Grand Duchy, allowing you to make a stopover on your morning commute. Most of our laboratories are open from 6 a.m. to offer you greater flexibility. To facilitate your access to our centres, you can consult the map which will enable you to easily locate those located near the motorways most frequently used by border workers.

How does a blood test or medical analysis work in Luxembourg?

If you are a cross-border commuter, you do not need to apply for a blood test or sample in the Grand Duchy of Luxembourg. To be entitled to the same benefits as a resident, all you have to do is

  • To be affiliated to the Caisse Nationale de Santé (National Health Fund) 
  • Have a medical prescription from a Luxembourg or foreign doctor (Belgian, French or German)

Your results will be sent to your doctor regardless of the country in which he or she practices.

You will also have access to your results in real time thanks to our secure platform MYLAB accessible from the web or via the smartphone application (iOS or Android).

Is my foreign prescription valid in Luxembourg?

A medical prescription issued by a European doctor is valid in Luxembourg. You can therefore go to one of our centres without an appointment with a Belgian, German or French prescription and be covered by the CNS without advance payment under the third-party payment scheme.

My doctor does not practice in Luxembourg, will he receive my test results?

Your doctor will receive your results in real time thanks to the results consultation tools available to doctors. A paper copy can also be sent by post. There is no difference between a doctor practising in Luxembourg or in a border country.

Do I have to pay in advance?

In Luxembourg, the cross-border commuter will receive the same benefits as a Luxembourg resident. You do not have to pay anything in advance as part of the third-party payment procedure. The laboratory is reimbursed directly by the CNS for the tests carried out.

Some tests, known as "hors-nomenclature", may not be covered by the CNS but if you have a complementary health insurance, it is possible that your contract covers the possible costs related to these "hors-nomenclature" tests.

We invite you to ask our nurse for details on the coverage of the analyses prescribed during the sampling.
