Reimbursement of Ambulance Costs: The Most Economical Route Applies

Imagine: you are a property owner in Cholet, and after a functional rehabilitation course in Angers, you return home by ambulance, accompanied by your wife. The bill amounts to €500, but your health insurance fund refuses to reimburse you in full, considering that the tariff applied is too high. What can you do?

This very real situation was decided by the French Supreme Court in 1973. The judges established a simple but often overlooked principle: even in the absence of a legal tariff, funds must reimburse transport costs according to the most economical route. In other words, if an ambulance based in Angers costs less than an ambulance from your residence, the fund may limit its reimbursement to the lower tariff.

But what exactly does this change for you, whether you are a property owner, tenant, or real estate professional? On the surface, this decision concerns health transport. In reality, it illustrates a general principle of social security law: the obligation to minimise costs. And it can have consequences in other areas, such as reimbursement of medical or paramedical expenses.

The Facts: A Story Like Many Others

Mr X, a social security insured person residing in Granville (Manche), undergoes a functional rehabilitation course in Paris. At the end of this course, he is taken home by ambulance. Notably, the ambulance comes from Granville, his town of residence, and his wife accompanies him. The transporter charges for the journey based on the approved tariff in Manche, which is higher than that of Paris.

The primary health insurance fund refuses to cover the full cost. It considers that the ambulance should have been chosen from the place of the course (Paris), where the tariff is cheaper. Mr X contests: according to him, no text imposes a specific tariff, and the fund must reimburse the tariff in force in his residence, since that is the place where the transport was carried out.

The case is brought before the first instance commission, then before the Court of Cassation. The debate focuses on the interpretation of Articles L. 321-1 and R. 322-10 of the Social Security Code (the texts governing reimbursement of transport costs). The fund argues that transport must be reimbursed according to the most economical route, even if this involves taking an ambulance from another locality. Mr X replies that the fund was never consulted on the choice of ambulance or on the medical necessity of his wife's presence.

The Reasoning of the Court — Analysed

The Court of Cassation rules in favour of the fund. Its reasoning has two points.

First, it recalls that no legal or regulatory provision imposes a specific tariff for reimbursing ambulance transport costs on the funds. In other words, the legislature did not set a national scale. The funds therefore have a certain margin of discretion.

Second, and this is the core of the decision, the funds are nevertheless required to settle these costs only according to the most economical route. This principle stems from the obligation of sound management of public funds. In clear terms, the fund must choose the least costly mode of transport, provided that the medical needs of the insured person are satisfied.

Applied to the facts, this means that the fund was not required to reimburse on the basis of the Granville tariff, which was higher than the Paris tariff. Especially since Mr X had not sought the fund's prior agreement on two key elements: the medical necessity of being accompanied by his wife, and the use of an ambulance from his residence rather than from the place of the course.

What few people know is that this decision is part of a consistent body of case law: funds must control the appropriateness of costs incurred. If the insured person chooses a more expensive transport without medical justification, the fund may reduce its reimbursement. This is an application of the principle of proportionality.

What This Changes for You — Concretely

For social security insured persons (property owners, tenants, etc.): if you need to be transported by ambulance, first check whether the transporter is approved and whether its tariff complies with that of the place where you are picked up. If you opt for an ambulance from your residence, which is more expensive, request prior agreement from your fund, especially if an accompanying person is present. Otherwise, you risk not being fully reimbursed.

For real estate professionals: this decision may seem far removed from your activity, but it illustrates a principle that applies to other reimbursements (e.g., medicalised removal costs). If a tenant or property owner needs to be transported for medical reasons, advise them to inquire about local tariffs.

Concrete example: in Beaupréau-en-Mauges, the tariff for an ambulance may be €150 for a local journey, whereas an ambulance from Angers would cost €200. If you are hospitalised in Angers and return home to Beaupréau, the fund will reimburse based on the Angers tariff, unless you medically justify the need for a local ambulance (e.g., follow-up by your local GP).

Be careful, however: this decision dates from 1973, but it is still cited. The texts have evolved, notably with the setting of reference tariffs by decree. However, the principle of the most economical route remains a safeguard for funds.

Four Tips to Avoid This Type of Dispute

• Request a prior quote: before any transport, obtain a quote from the ambulance company and submit it to your fund. This will allow you to know the reimbursable amount.
• Medically justify accompaniment: if you need to be accompanied by a relative, obtain a medical prescription specifying this necessity. The fund may then accept it.
• Choose the most economical transport: if your state of health allows, choose the cheapest ambulance, even if it is not from your locality. You will avoid a shortfall.
• Keep all supporting documents: transport voucher, prescription, fund agreement. In case of dispute, these documents are essential.

This decision is part of a line of Court of Cassation rulings from the 1970s-1980s that consolidate the principle of the most economical route. For example, in a judgment of 7 February 1974 (No. 72-14.567), the Court held that the fund could refuse to reimburse air transport if a train was sufficient and cheaper.

Since then, the texts have evolved: Article R. 322-10 of the Social Security Code now provides that transport costs are reimbursed on the basis of the most economical tariff, except in medical emergencies. The 1973 case law has thus been codified. However, disputes persist over the notion of "most economical route": is it the cheapest tariff or the total cost including ancillary expenses? Courts decide on a case-by-case basis.

For the future, the trend is towards strengthening fund control. With digitalisation, reimbursements are automated, but insured persons must be vigilant: non-compliant transport may be rejected.

Checklist Before Acting

1. Is the transport medically necessary? Obtain a detailed medical prescription (place, reason, possible accompaniment).
2. What is the local tariff? Check with your fund for the reference tariff of the place of pick-up.
3. Do I have prior agreement? For any non-urgent transport, request written agreement from the fund before the journey.
4. What documents to keep? Keep the prescription, quote, invoice and fund agreement.
5. In case of refusal of reimbursement: Refer the matter to the amicable appeal commission within two months of the refusal, then possibly to the judicial court.
