The insured person is considered a cross-border worker if they work (and are insured) in a different EU country than the one they reside in and under the condition that they return to the country of residence every day or at least once a week. In this case, the country competent in social security matters is the country where they work.

The BL1 form is a document of legal entitlement to healthcare benefits delivered by the competent country (country where contributions are payed) and allows registration in the country of residence. In this case, healthcare is delivered in the country of residence as if the concerned person was insured there. The BL1 form delivered by the competent healthcare fund must be presented to the health fund in the country of residence. The healthcare fund from the country of residence confirms the registration of the form to the competent healthcare fund.

The cross-border worker insured in Luxembourg must register with the health insurance fund of their place of residence in order to benefit from healthcare reimbursements. The CNS issues a document of entitlement for this purpose: the BL1 form, as provided for in the Belgium-Luxembourg agreement of 24th March 1994.

Following registration as a cross-border worker from Belgium, the BL1 form is normally sent automatically to to the private address of the insured person, who should present the form to a Belgian health insurance fund of their choice.

If the insured person does not receive the BL1 within fifteen days following the submission of the declaration of entry to the CCSS (Joint Centre for Social Security) they are advised to order the BL1.

As per article 5 of the Belgium-Luxembourg agreement of 24th March 1994, the cross-border worker and members of their family who are entitled to benefits in kind on Belgian territory enjoy the right, where applicable, to full reimbursement under Luxembourg law.

For full information concerning complementary reimbursements, the insured person can contact their Belgian health insurance fund (mutuelle) or the CNS, as the case may be.

The cross-border insured and the members of their family are entitled to the same benefits under the same terms and conditions as those to which the residents of the Grand Duchy of Luxembourg are entitled.

The law of the insured's country of residence applies concerning the determination of who qualifies for benefits in their capacity as a member of the insured's family.

For this purpose, the Belgian insurance fund (mutuelle) transmits a document of entitlement to the CNS attesting to the fact that members of the family are co-insured in the name of the person insured in Luxembourg.

With regard to reimbursement of healthcare, treatment provided in the country of residence can only be reimbursed by the country of residence according to its own rates, tariffs and terms.

Only Belgian cross-border workers and former Belgian cross-border workers benefit from a specific regime based on the provisions of the Belgium-Luxembourg agreement of 24 March 1994.

This agreement specifies that the CNS will provide an additional reimbursement for treatment provided in Belgium at the level of the average reimbursement rate in Luxembourg (currently 93.9% ).

The Belgian healthcare fund transmits the necessary information for the complementary reimbursement.

You can order the form by contacting the CNS.

The cross-border worker insured in Luxembourg must register with the health insurance fund of their place of residence in order to benefit from health care reimbursements. The CNS issues a document of entitlement for this purpose: the S1 form

Following registration as a cross-border worker from Germany, the S1 form is normally sent automatically to to the private address of the insured person, who should present the form to a German statutory health insurance fund (gesetzliche Krankenkasse) of his choice.

If the insured person does not receive the S1 within the fifteen days following the submission of the declaration of entry to the CCSS (Joint Centre for Social Security) they are advised to order the S1.

The cross-border insured and the members of their family are entitled to the same benefits under the same terms and conditions as those to which the residents of the Grand Duchy of Luxembourg are entitled.

The law of the insured's country of residence applies concerning the determination of who qualifies for benefits in their capacity as a member of the insured's family.

For this purpose, the health insurance fund of the country of residence contacts the CNS electronically via EESSI (electronic exchange of social security information) using form S071 to request the S072 equivalent to the digital version of the S1. The health insurance fund in the country of residence will confirm registration by returning form S073.
