October 30 marked a turning point in the Luxembourg healthcare system: the Association of Doctors and Dentists (AMMD) sent the National Health Fund (CNS) the official letter terminating their agreements. This decision, approved by a large majority at the extraordinary general meeting on 8 October, puts an end to a framework that has been in force for decades, governing the remuneration, conditions of practice and obligations of self-employed practitioners.

Behind this break, doctors are denouncing a system that they feel has become unsuited to the reality of their practice. The AMMD refers to a "legal and regulatory straitjacket", not to say "unconstitutional", that limits professional freedom and prevents patients from being treated quickly. In other words, the automatic agreement between doctors and the CNS - which sets tariffs and regulates reimbursements - has become too rigid. Practitioners now want a "selective and regulated" agreement, where the profession would have a say in the quality and organisation of care.

One of the most sensitive points concerns pricing. At present, the "key letter" - the basis on which medical fees are calculated - is only increased by a maximum of 2.68% every two years. This time, the government was proposing 1.34%, at an estimated cost to the budget of €12 million, compared with the full increase of €24 million. This moderation, presented as necessary for the stability of the system, was seen as a provocation by the AMMD, which denounces a structural imbalance to the detriment of liberal medicine.

Faced by this breakdown, the Minister for Health and Social Security, Martine Deprez, is trying to calm things down. She pointed out that the agreement would remain in force for twelve months, to allow time for "responsible and constructive" dialogue. The minister said that she wanted to put "the patient, his needs and his interests back at the centre of the system". At the same time, the government is preparing a quadripartite meeting bringing together the CNS, the AMMD and the social partners to rethink the funding and governance model.

This crisis comes against a tense budgetary backdrop. The CNS has a growing deficit and depends on increasingly large public transfers. The draft budget for 2026 provides for a state contribution of 59 million euros, compared with the 20 million initially announced. For Martine Deprez, the sustainability of the system must be preserved without compromising the quality of care. For doctors, this financial prudence above all reflects a lack of vision and structural reforms.

Politically, the issue is putting the government under pressure. The governing coalition has to find a balance between budgetary discipline and recognition of the malaise of the healthcare professions. The liberal opposition is calling for a partial liberalisation of contractual arrangements, while the left is warning against a two-tier system in which only the most affluent would be able to obtain rapid treatment. In this tense climate, healthcare becomes a highly symbolic terrain: that of the relationship between individual freedom and collective solidarity.

For patients, nothing changes immediately. Consultations will remain covered by the agreement during the twelve-month transitional period. However, if no agreement is reached by autumn 2026, medical procedures could no longer be automatically reimbursed. In practical terms, this would mean free fees, advanced by the patient, then partially reimbursed by the CNS according to its scales. A scenario that everyone wants to avoid, but that no one is ruling out.

The AMMD says it is ready to negotiate a "new agreement tailored to the real needs of liberal medicine and the expectations of the population". The government, for its part, is promising to reform the legal framework by making the law on medical practice more flexible, modernising the hospital law, creating a statute for medical societies and speeding up the digitisation of the healthcare system. These are all initiatives that, if they succeed, could profoundly transform the relationship between doctors, the state and the insured.

In the meantime, this rupture is acting as an eye-opener. It lays bare the tensions in a model that has long been considered stable: that of a small, rich country capable of guaranteeing rapid access to quality care for all. But this balance is costly. Between professional demands and financial imperatives, Luxembourg is rediscovering that healthcare, before being a public service, remains a fragile political compromise.
