Imagine: you live in Biscarrosse, in the Landes. Your doctor prescribes mud baths for stubborn arthritis. Problem: the nearest physiotherapist, in Parentis-en-Born, does not offer this type of treatment. You must travel an extra 30 kilometres to a specialised practice. Upon your return, the Caisse primaire d'assurance maladie (CPAM) refuses to fully reimburse your transport costs, claiming you should have made do with the nearest practitioner. Unfair, isn't it?
Yet, a decision of the Court of Cassation of 21 July 1986 (No. 84-11.454) rules in favour of insured persons in this situation. It states that when the prescribed treatment cannot be provided by the nearest healthcare professional, transport to another practitioner is imposed by the necessities of the treatment and must be covered at 100%. But what exactly does this mean for you, whether you are a homeowner or tenant in the Landes or elsewhere?
This article analyses this little-known case law, explains how to assert your rights, and gives practical tips to avoid reimbursement refusals. In short, if your physio does not do mud baths, the CPAM cannot penalise you.
The Facts: A Story Like Many Others
Ms X, a social security beneficiary living in a rural municipality (say, around Parentis-en-Born), suffered from joint pain. Her GP prescribed "specific treatments consisting of mud baths" – a thermal therapy often indicated for rheumatism. However, the nearest physiotherapist to her home did not practise this type of treatment. Ms X therefore had to go to another, more distant physiotherapist who could provide mud baths.
At the time, the Social Security Code (Article L. 283) provided that an insured person's transport costs were covered only if the transport was "imposed by the necessities of the treatment". The CPAM considered that Ms X should have made do with the nearest physio, even if he did not practise mud baths. It therefore refused to fully reimburse the transport costs, covering only the distance to the nearest practice. Ms X challenged this refusal before the first instance commission for social security disputes.
The commission ruled in her favour, but the CPAM appealed. The case went up to the Court of Cassation, which upheld the commission's decision in 1986. The high court held that, since the CPAM did not dispute either the medical necessity of the mud baths, their regular prescription, or the impossibility of receiving them from the nearest practitioner, the transport to another practitioner was indeed imposed by the necessities of the treatment. In short, the insured person had no choice: without this transport, she could not have received the prescribed treatment. The costs therefore had to be covered in full.
The Court's Reasoning — Analysed
The decision is based on a strict interpretation of Article L. 283 of the Social Security Code (now codified in Article L. 321-1 of the same code), which provides that transport costs are covered when they are "imposed by the necessities of the treatment". The Court of Cassation clarifies that this condition is met as soon as two elements are present: 1) the medical prescription is regular and the fund does not dispute the necessity of the treatment; 2) the nearest practitioner is unable to provide the prescribed treatment.
In other words, the judges consider that the insured person should not suffer a loss of opportunity to access appropriate treatment simply because they live far from a specialised practitioner. The reasoning is pragmatic: if the local physio does not do mud baths, it is not the patient's fault. The CPAM cannot refuse coverage on the grounds that transport should have been limited to the journey to the nearest practitioner.
Note, however: the Court specifies that the first instance commission can decide this dispute without resorting to a medical expert opinion, because it is not a medical dispute (about the nature of the treatment), but simply a question of organising care. What few people know is that this decision saves insured persons from the cumbersome technical expert procedure, which could have delayed reimbursement by several months.
undefined, I have come across cases where the CPAM tried to challenge the very principle of the prescription (for example, by considering that mud baths were not medically necessary). Here, the Court rules out this possibility: if the fund does not dispute the prescription, it cannot indirectly go back on it by refusing transport. In summary, the decision enshrines the right to effective access to care, without geographical discrimination.
What This Means for You — Practically
For social security beneficiaries, this case law is a valuable weapon. If you live in a rural area like Parentis-en-Born or Biscarrosse, and your doctor prescribes specific treatments (balneotherapy, respiratory physiotherapy, etc.) that the nearest professional does not practise, you are entitled to full reimbursement of your transport costs to a more distant practice.
Let's take a concrete example: you live in Parentis-en-Born and your doctor prescribes sessions of physiotherapy with manual lymphatic drainage. The nearest physio, in Sanguinet, does not practise this technique. You have to go to Mont-de-Marsan, 40 km away. The CPAM cannot reimburse you only for the 15 km to Sanguinet. It must cover the entire journey (80 km round trip), i.e., about €40 in transport costs (based on the mileage rate of €0.50/km). Over a course of 20 sessions, that's €800, a significant sum.
If you are a landlord or tenant, this decision concerns you indirectly: it shows that the right to health takes precedence over considerations of geographical proximity. But more directly, if you are in a dispute with the CPAM over a refusal of transport, you can rely on this ruling. Be careful, however: the CPAM may challenge the medical necessity of the treatment. Make sure your prescription is precise and justified.
For healthcare professionals (physios, doctors), this decision encourages them to write detailed prescriptions, mentioning the exact nature of the treatment and the absence of a competent practitioner nearby. This secures reimbursement for their patients.
Four Tips to Avoid This Type of Dispute
- Get a precise medical prescription: Ask your doctor to write a prescription detailing the exact nature of the treatment (e.g., "mud baths", "lymphatic drainage", etc.) and to mention that the nearest practitioner does not practise these treatments. This avoids any dispute over the necessity of transport.
- Check with your CPAM before travelling: Before incurring costs, contact your fund to find out whether the transport will be covered. You can obtain prior agreement (form S3125). Keep a written record of this agreement.
- Keep all supporting documents: Keep the prescriptions, transport invoices (taxi, ambulance, or certificate for your vehicle), and any document proving that the nearest practitioner could not provide the treatment (e.g., a certificate from the physio).
- If refused, challenge promptly: You have two months to refer the matter to the CPAM's amicable appeals commission, then to the judicial court (social division). Rely on the 1986 Court of Cassation decision to support your claim.

This 1986 decision is part of a consistent line of Court of Cassation rulings favourable to insured persons. For example, a ruling of 14 November 1996 (No. 94-20.183) extended this reasoning to transport for treatment provided by a lawyer, when the local GP could not provide it. More recently, the Court confirmed that the condition "imposed by the necessities of the treatment" must be interpreted broadly, taking into account the actual healthcare provision (Cass. 2e civ., 14 September 2017, No. 16-20.124).
The trend is therefore towards protecting insured persons, especially in medical deserts. However, the CPAM can still challenge the medical prescription itself (e.g., by considering that the treatment is not necessary). In that case, a medical expert will be appointed. But if the fund does not raise this point, it cannot refuse transport.
For the future, the Social Security Financing Act for 2023 introduced a prior authorisation procedure for certain long-distance transport. This could complicate matters, but the 1986 case law remains applicable: if the transport is medically justified and the nearest practitioner cannot provide the treatment, coverage must be full.
Checklist Before Acting
- 1. Check your prescription: Has your doctor specified the nature of the treatment? Has he mentioned the absence of a competent practitioner nearby? If not, ask him to complete the prescription.
- 2. Contact the CPAM: Before any travel, call your fund to find out whether the transport is covered. Ask for written agreement (email or letter).
- 3. Gather evidence: Obtain a certificate from the nearest physio stating that he does not practise the prescribed treatment. Keep transport receipts (invoice, mileage record).
- 4. If refused, act quickly: You have 2 months to challenge. Refer the matter to the CPAM's amicable appeals commission (CRA) by registered letter with acknowledgement of receipt, attaching the documents and citing the 1986 ruling.
- 5. If the CRA rejects your appeal: Refer the matter to the judicial court (social division) within 2 months of notification. You can be assisted by a specialised lawyer.
