Civil Law And Cross-Border Healthcare Claims In Europe

1. Introduction

Cross-border healthcare claims in Europe arise when a patient receives, seeks, or is denied healthcare in a country different from the country in which the patient is insured or ordinarily resident, and then brings a claim concerning:

reimbursement of medical expenses;

refusal of prior authorisation;

hospital or non-hospital treatment abroad;

emergency treatment;

medical negligence;

delayed treatment;

defective healthcare services;

patient rights;

discrimination or unequal access;

compensation for injury;

recognition of medical decisions;

cross-border health insurance.

The European legal framework is unusual because healthcare disputes sit at the intersection of civil liability, social security, EU free-movement law, private international law and national medical law.

A patient may therefore have several different legal questions:

Which country must pay?
Which country may hear the claim?
Which country's healthcare law applies?
Was prior authorisation required?
Was the refusal lawful?
Was the medical treatment negligent?
What compensation is available?

The CJEU has developed a substantial body of case law concerning cross-border healthcare reimbursement, particularly under the freedom to provide services and EU social-security coordination rules. Directive 2011/24/EU subsequently codified and developed important aspects of that case law. (curia)

2. Meaning of Cross-Border Healthcare

Cross-border healthcare exists where healthcare is provided in a Member State other than the patient's relevant State of affiliation/residence.

Example

A patient is insured in France but travels to Belgium for surgery.

Possible dispute:

France refuses to reimburse the Belgian treatment because the patient did not obtain prior authorisation.

Another example:

A patient from Romania receives cardiac surgery in Germany because treatment could not be provided adequately or within a medically justifiable period in Romania.

A third example:

A patient from Hungary receives emergency eye surgery in Germany and later seeks reimbursement from the Hungarian health system.

These situations generate different legal questions depending upon whether the treatment was:

planned;

emergency;

hospital;

non-hospital;

medically necessary;

authorised;

unauthorised.

3. Main European Legal Framework

A. Article 56 TFEU — Freedom to Provide Services

Healthcare services can constitute services for EU free-movement purposes.

The CJEU established this principle in the early cross-border healthcare cases.

A national measure that discourages patients from obtaining medical services in another Member State can constitute a restriction on the freedom to provide services.

This was fundamental to Kohll and later cases. (curia)

4. Regulation 883/2004

EU social-security coordination is principally governed by Regulation (EC) No 883/2004 and its implementing rules.

Article 20 is particularly important for planned healthcare in another Member State.

Generally, prior authorisation can be required for certain cross-border treatment, particularly hospital and highly specialised treatment.

But authorisation must be granted where the applicable conditions are satisfied, including where necessary treatment cannot be provided within a medically justifiable period in the patient's State of residence/affiliation.

5. Directive 2011/24/EU

The Cross-Border Healthcare Directive created a more systematic framework for patients receiving healthcare in another Member State.

It addresses:

patient rights;

reimbursement;

prior authorisation;

information;

prescriptions;

quality and safety;

continuity of care;

cooperation between Member States.

Importantly, the Directive operates without prejudice to Regulation 883/2004. The CJEU has expressly recognised that the Directive codified and developed aspects of its earlier case law. (InfoCuria)

6. Civil Liability vs Reimbursement

A crucial distinction must be made.

Reimbursement claim

Patient says:

"My home country's health system should pay for treatment I received abroad."

This is principally a social-security/free-movement question.

Medical-negligence claim

Patient says:

"The foreign hospital or doctor negligently injured me."

This is primarily a civil-liability/private-international-law question.

Contractual claim

Patient says:

"The private healthcare provider breached its treatment agreement."

This can involve contract law and private international law.

Therefore:

Not every cross-border healthcare claim is a reimbursement claim.

7. Case Law 1 — Kohll

Raymond Kohll v Union des Caisses de Maladie

CJEU, Case C-158/96, judgment of 28 April 1998

Facts

Mr Kohll was insured in Luxembourg.

His daughter required orthodontic treatment in Germany.

The Luxembourg authorities refused prior authorisation because:

the treatment was not considered urgent; and

it could be provided in Luxembourg.

Decision

The CJEU held that medical treatment provided by an orthodontist outside a hospital constitutes a service.

A national requirement for prior authorisation could constitute an obstacle to the freedom to provide services.

The Luxembourg restriction was not justified on the facts because the treatment did not create a serious threat to the financial balance of the social-security system. (curia)

Principle

Patients may rely on EU free-movement principles when obtaining non-hospital medical treatment in another Member State.

Importance

Kohll is one of the foundational cases in European cross-border healthcare law.

8. Case Law 2 — Decker

Nicolas Decker v Caisse de Maladie des Employés Privés

CJEU, Case C-120/95, judgment of 28 April 1998

Facts

Mr Decker, insured in Luxembourg, purchased spectacles from an optician in Belgium.

The Luxembourg social-security system refused reimbursement because he had not obtained prior authorisation.

Decision

The CJEU found that the national rule restricted the relevant EU free-movement principle concerning goods.

The Court held that reimbursement could not simply be denied because the medical product was purchased in another Member State without prior authorisation. (curia)

Importance

Although Decker concerned spectacles rather than treatment itself, it helped establish the broader principle that national healthcare reimbursement systems cannot unnecessarily discourage cross-border acquisition of healthcare-related goods.

Principle

Cross-border healthcare-related expenditure can fall within EU free-movement rules even where the dispute concerns reimbursement rather than the medical treatment itself.

9. Case Law 3 — Geraets-Smits and Peerbooms

Geraets-Smits v Stichting Ziekenfonds VGZ and Peerbooms v Stichting CZ Groep Zorgverzekeringen

CJEU, Case C-157/99, judgment of 12 July 2001

Facts

Two Dutch patients received treatment abroad.

Ms Geraets-Smits received treatment in Germany for Parkinson's disease.

Mr Peerbooms received specialised treatment in Austria after falling into a coma.

Their Dutch insurers refused reimbursement under the national healthcare system.

Decision

The CJEU confirmed that medical treatment constitutes a service even when provided through a national social-security system.

However, the Court accepted that prior authorisation for hospital treatment can, in principle, be justified.

The reasons include:

maintaining a balanced medical and hospital service;

planning healthcare capacity;

controlling costs;

preventing waste of financial, technical and human resources.

But the conditions for refusing authorisation must be objective, non-discriminatory and proportionate. (InfoCuria)

Principle

Prior authorisation for cross-border hospital treatment can be lawful, but the authorisation system must satisfy proportionality and objective medical criteria.

10. Case Law 4 — Müller-Fauré and van Riet

Müller-Fauré v Onderlinge Waarborgmaatschappij OZ Zorgverzekeringen and van Riet v Onderlinge Waarborgmaatschappij ZAO Zorgverzekeringen

CJEU, Case C-385/99, judgment of 13 May 2003

Facts

Ms Müller-Fauré obtained dental treatment in Germany during a holiday without prior authorisation.

Ms van Riet sought treatment in Belgium because it could be provided sooner than in the Netherlands.

The Dutch system refused reimbursement.

Decision

The CJEU distinguished between:

Hospital care

Prior authorisation could be justified by the need for planning and maintaining healthcare capacity.

Non-hospital care

A general prior-authorisation requirement was much more difficult to justify.

The Court therefore strengthened the distinction between hospital and non-hospital treatment. (curia)

Principle

The justification for prior authorisation depends significantly on the nature of the healthcare involved.

Importance

This case became an important foundation for the later Cross-Border Healthcare Directive.

11. Case Law 5 — Watts

Yvonne Watts v Bedford Primary Care Trust and Secretary of State for Health

CJEU, Case C-372/04, judgment of 16 May 2006

Facts

Ms Watts was resident in England and required hip replacement surgery.

She travelled to France to receive treatment.

She sought reimbursement from the English health system.

Decision

The CJEU confirmed that hospital treatment can fall within the freedom to provide services.

A prior-authorisation system can be justified for hospital treatment, but refusal must comply with EU law.

In particular, authorisation cannot be refused where treatment cannot be provided in the patient's home system within a medically justifiable period, taking account of the patient's condition and medical history.

The Court also addressed reimbursement and found that EU law could require reimbursement at the level that would have been assumed for equivalent treatment under the home system. (curia)

Principle

A healthcare authority cannot use waiting-list arrangements to justify refusal where the patient cannot obtain necessary treatment within a medically justifiable period.

12. Case Law 6 — Elchinov

Elchinov v Natsionalna zdravnoosiguritelna kasa

CJEU, Case C-173/09, judgment of 5 October 2010

Facts

Mr Elchinov was insured in Bulgaria.

He required hospital treatment abroad.

The Bulgarian authorities refused reimbursement.

The case concerned both prior authorisation and the effect of EU law on national decision-making.

Decision

The CJEU confirmed that a system cannot categorically exclude reimbursement for hospital treatment received in another Member State merely because prior authorisation was absent.

In particular, the rules must accommodate situations where the patient's medical condition or urgent need prevents the patient from obtaining or awaiting prior authorisation.

The Court also reaffirmed the primacy of EU law over conflicting national rules. (InfoCuria)

Principle

Prior authorisation systems cannot operate mechanically where the patient's medical circumstances make prior authorisation impossible or unreasonable.

13. Case Law 7 — Petru

Petru v Casa Județeană de Asigurări de Sănătate Sibiu

CJEU, Case C-268/13, judgment of 9 October 2014

Facts

Ms Petru, a Romanian patient with serious cardiovascular disease, required heart surgery.

She alleged that the Romanian hospital lacked:

essential medication;

basic medical supplies;

adequate infrastructure;

sufficient beds.

She therefore sought treatment in Germany and reimbursement from the Romanian healthcare system.

Decision

The CJEU held that reimbursement could not necessarily be refused merely because treatment technically existed in the patient's home country.

The national court had to consider whether the actual availability of necessary infrastructure and resources meant that the treatment could not be provided within a medically justifiable period.

The assessment had to consider all hospitals capable of providing the treatment. (curia)

Principle

Availability of treatment must be genuine and practical, not merely theoretical.

Importance

This is especially important in claims alleging inadequate healthcare infrastructure.

14. Case Law 8 — WO

WO v Vas Megyei Kormányhivatal

CJEU, Case C-538/19, judgment of 6 October 2021

Facts

The case concerned cross-border healthcare and reimbursement where treatment abroad offered a different therapeutic approach.

The patient had obtained a second medical opinion in another Member State concerning an alternative treatment.

Decision

The CJEU examined the interaction between:

Regulation 883/2004;

freedom to provide services;

Directive 2011/24.

The Court confirmed that national reimbursement rules must comply with EU requirements and that Member States retain discretion to organise their healthcare systems, but that discretion is constrained by EU free-movement principles. (InfoCuria)

Principle

National healthcare systems retain organisational autonomy, but reimbursement conditions cannot unjustifiably obstruct cross-border healthcare.

15. Case Law 9 — Emergency Cross-Border Surgery

A particularly important line of CJEU jurisprudence concerns emergency treatment abroad.

In the case concerning emergency eye surgery in Germany involving a Hungarian insured person, the CJEU considered whether national rules could completely exclude reimbursement where emergency circumstances prevented prior authorisation.

The Court held that EU law can preclude such an absolute exclusion where the patient's circumstances meant that the patient could not reasonably obtain or await authorisation. (curia)

Principle

Emergency circumstances can materially alter the legal consequences of missing prior authorisation.

16. Case-Law Table

17. Prior Authorisation

Prior authorisation is one of the most litigated issues.

The basic question is:

Can a Member State require its insured citizens to obtain permission before receiving treatment abroad?

The answer is:

Non-hospital treatment

Prior authorisation is generally more difficult to justify.

Hospital treatment

Prior authorisation can be justified because hospitals require:

capacity planning;

financial planning;

specialist equipment;

medical personnel;

resource allocation.

This distinction originated in Kohll, Geraets-Smits, and Müller-Fauré. (curia)

18. Medically Justifiable Waiting Time

A particularly important rule comes from Watts and related cases.

The question is not merely:

"Is treatment available?"

Instead:

Can the patient receive appropriate treatment within a medically justifiable period?

The assessment considers:

patient's medical condition;

history;

likely progression;

pain;

degree of disability;

urgency;

clinical consequences of delay.

Therefore, a long administrative waiting list cannot automatically defeat a patient's claim to cross-border treatment.

19. Quality of Healthcare

Cross-border healthcare claims can involve allegations that:

treatment was inadequate;

medical standards were breached;

hospital facilities were deficient;

diagnosis was delayed;

surgery was negligently performed.

The CJEU reimbursement cases do not automatically establish medical negligence.

For negligence, the claimant normally has to establish under the applicable national law:

duty;

breach;

causation;

damage.

The applicable private-international-law rules must then determine which country's substantive civil-liability law applies.

20. Medical Malpractice Across Borders

Consider:

French patient → Belgian hospital → negligent surgery → patient returns to France.

Potential claims include:

Contractual

The patient may claim breach of the healthcare contract.

Tortious

The patient may claim medical negligence.

Insurance

The patient's health insurer may seek reimbursement or recovery.

Social security

The patient may seek reimbursement for treatment expenses.

These claims may have different jurisdictional and applicable-law analyses.

21. Cross-Border Healthcare and Brussels I bis

Where the dispute is a civil/commercial claim against a healthcare provider, Brussels I bis may become relevant.

For example:

Patient domiciled in France sues a private Belgian hospital for negligent surgery.

Potential jurisdictional questions include:

defendant's domicile;

place where harmful event occurred;

consumer jurisdiction, where applicable;

contractual jurisdiction.

However, social-security disputes between an insured person and a public social-security institution may fall outside the ordinary civil-and-commercial framework.

Therefore:

The legal status of the defendant and nature of the claim matter.

22. Healthcare Provider Liability

A private hospital can potentially face civil liability for:

negligent surgery;

misdiagnosis;

medication errors;

inadequate monitoring;

failure to obtain informed consent;

defective medical devices;

hospital-acquired infection;

failure of emergency care.

The applicable substantive law will depend on the relevant private-international-law rules and the characterisation of the claim.

23. Informed Consent

Cross-border healthcare increases the importance of informed consent.

A patient should ordinarily receive information concerning:

proposed treatment;

material risks;

alternatives;

expected outcomes;

consequences of refusal.

A dispute may arise if:

Patient consents in France but surgery takes place in Germany.

The applicable civil law may depend on whether the claim concerns:

contractual obligations;

medical negligence;

personal rights;

informed-consent standards.

24. Medical Records

Cross-border treatment also creates disputes concerning:

access to medical records;

transfer of records;

confidentiality;

correction of inaccurate records;

electronic health records;

data protection.

The GDPR can become relevant alongside national medical confidentiality laws.

25. Prescription and Continuity of Treatment

The Cross-Border Healthcare Directive also facilitates:

recognition of prescriptions;

continuity of treatment;

information exchange;

patient mobility.

A patient treated in Belgium may need medication after returning to France.

A legal dispute may arise if:

the prescription is not recognised;

the medicine is unavailable;

reimbursement is refused.

26. Emergency Healthcare

Emergency cases receive special consideration.

A patient cannot always be expected to:

locate the competent institution;

complete paperwork;

obtain authorisation;

wait for administrative approval;

before receiving life-saving treatment.

The CJEU's case law recognises that individual medical circumstances can make prior authorisation impossible or unreasonable. (curia)

27. Patient Mobility

European healthcare law attempts to balance two interests.

Patient interest

The patient should have meaningful access to healthcare in another Member State.

State interest

The Member State must be able to:

plan healthcare capacity;

control expenditure;

maintain hospitals;

preserve specialist facilities;

ensure universal access.

The CJEU has therefore not created unlimited patient freedom.

Instead, the approach is:

Cross-border access + legitimate healthcare planning + proportionality.

28. Financial Liability

Suppose treatment abroad costs:

€20,000

but equivalent treatment in the patient's home country would cost:

€12,000.

The reimbursement question is not necessarily:

"Must the home State pay €20,000?"

EU law generally operates through the reimbursement rules of the applicable system and Directive 2011/24.

Reimbursement may therefore be limited to the amount that would have been assumed under the home system, subject to the relevant rules. (curia)

29. Unauthorised Treatment

Absence of prior authorisation does not always mean:

No reimbursement whatsoever.

The cases demonstrate that courts must consider:

whether authorisation was legally required;

whether the treatment was hospital care;

whether the refusal criteria were lawful;

whether emergency circumstances existed;

whether the patient could realistically obtain authorisation;

whether the treatment satisfied the relevant medical criteria.

Elchinov and the later emergency-treatment jurisprudence are particularly important. (InfoCuria)

30. Inadequate Domestic Healthcare

Petru is especially important here.

A Member State cannot necessarily argue:

"Treatment exists somewhere in our country."

The actual inquiry may include:

available facilities;

necessary equipment;

medicines;

specialist staff;

beds;

waiting time;

ability to perform the specific procedure.

The assessment is therefore practical rather than purely theoretical. (curia)

31. Religious and Personal Considerations

Cross-border healthcare litigation can also involve personal circumstances, including religious objections to particular treatment methods.

In C-243/19, the CJEU considered whether circumstances linked to a patient's religious beliefs could be relevant to the assessment of access to necessary hospital treatment and reimbursement under Directive 2011/24. (curia)

This demonstrates that "available treatment" can sometimes require analysis beyond merely asking whether a technically similar procedure exists.

32. European Civil-Law Structure

A cross-border healthcare claim can be analysed through the following structure:

Step 1 — Identify the claim

Reimbursement?

or

Medical negligence?

or

Contract?

or

Insurance?

↓

Step 2 — Identify the parties

patient;

hospital;

doctor;

insurer;

public health authority.

↓

Step 3 — Determine jurisdiction

Which country's court can hear the claim?

↓

Step 4 — Determine applicable law

Which national law governs liability or contractual rights?

↓

Step 5 — Apply EU healthcare rules

Especially:

Regulation 883/2004;

Directive 2011/24;

Article 56 TFEU.

↓

Step 6 — Determine remedy

reimbursement;

damages;

interest;

declaration;

authorisation;

compensation.

33. Hypothetical Example

Facts

A patient is insured in Italy.

He requires specialised cardiac surgery.

Italian authorities say that the procedure is available in Italy but that the waiting period is six months.

A German hospital can perform the surgery within three weeks.

The patient travels to Germany.

Italy refuses reimbursement because no prior authorisation was obtained.

Legal analysis

The patient must consider:

Is the treatment hospital treatment?

Was prior authorisation required?

Could treatment be provided in Italy within a medically justifiable period?

What was the patient's medical condition?

Would the six-month delay create medical risks?

Was the German treatment medically equivalent?

What reimbursement would Italian law provide?

Does Directive 2011/24 apply?

Do Regulation 883/2004 rules provide an alternative route?

Watts provides the central principle concerning medically justifiable waiting periods. (curia)

34. Second Hypothetical — Medical Negligence

A Spanish resident travels to France for surgery.

The French hospital negligently damages a nerve.

The patient returns to Spain and develops permanent disability.

The claim may involve:

French connection

hospital;

doctor;

treatment;

place of alleged negligence.

Spanish connection

residence;

continuing medical treatment;

consequences of injury.

The court must distinguish:

healthcare reimbursement

from

civil damages for negligence.

The applicable jurisdictional and choice-of-law rules may therefore differ.

35. Third Hypothetical — Emergency Treatment

A Hungarian resident suffers an acute eye condition while visiting Germany.

Emergency surgery is performed immediately.

The patient had no realistic opportunity to obtain prior authorisation.

Hungary subsequently refuses all reimbursement.

The CJEU's emergency-care jurisprudence indicates that an absolute exclusion cannot necessarily stand where the patient's circumstances made prior authorisation impossible or unreasonable. (curia)

36. Key Difference Between Major Cases

37. Important Legal Principles

Principle 1 — Healthcare is not outside EU free-movement law

Medical treatment can constitute a service.

Kohll established this foundational point. (InfoCuria)

Principle 2 — Prior authorisation is not automatically unlawful

For hospital treatment, authorisation can be justified.

But:

The authorisation conditions must be objectively justified and proportionate.

Geraets-Smits, Müller-Fauré and Watts establish this framework. (InfoCuria)

Principle 3 — Waiting lists matter

Treatment must be available within a medically justifiable period.

A purely administrative waiting list is not necessarily sufficient.

Watts is the leading authority. (curia)

Principle 4 — Actual healthcare capacity matters

Treatment must be genuinely available.

Petru demonstrates that inadequate medicine, infrastructure and capacity may affect the assessment. (curia)

Principle 5 — Emergencies receive special treatment

A patient cannot necessarily be denied reimbursement simply because prior authorisation was impossible to obtain before urgent treatment.

Elchinov and subsequent emergency jurisprudence are important. (InfoCuria)

Principle 6 — Healthcare systems retain autonomy

Member States may organise and finance their healthcare systems.

But national rules must comply with:

EU free-movement law;

proportionality;

non-discrimination;

applicable EU healthcare legislation.

38. Remedies

Depending on the type of claim, remedies can include:

1. Reimbursement

Payment of eligible treatment expenses.

2. Additional reimbursement

Where EU law requires reimbursement at the appropriate home-system level.

3. Damages

For medical negligence or contractual breach under applicable national law.

4. Declaration

A court may declare an authorisation refusal unlawful.

5. Interest

Interest may be recoverable under applicable national law.

6. Costs

Litigation costs may be awarded according to the procedural law of the competent court.

39. Major Litigation Challenges

Cross-border healthcare claims often involve:

determining whether treatment was hospital or non-hospital;

determining whether prior authorisation was required;

proving medical urgency;

proving unreasonable waiting time;

proving actual lack of capacity;

determining reimbursement level;

identifying the competent court;

determining applicable civil-liability law;

obtaining medical records from another State;

proving causation in medical-negligence cases;

enforcing judgments;

coordinating public insurance and private liability claims.

40. Conclusion

Cross-border healthcare claims in Europe are governed by a layered legal system rather than one single civil-law rule.

The foundational CJEU jurisprudence began with Decker and Kohll, establishing that cross-border healthcare can fall within EU free-movement principles. Geraets-Smits and Peerbooms recognised that prior authorisation can be justified for hospital treatment where necessary for healthcare planning and financial stability. Müller-Fauré strengthened the distinction between hospital and non-hospital treatment. Watts established the importance of medically justifiable waiting periods. Elchinov prevented national systems from applying prior-authorisation requirements mechanically in circumstances where patients could not realistically obtain or await authorisation. Petru confirmed that the actual availability of medical infrastructure matters, while WO demonstrates the continuing interaction between social-security coordination, the Cross-Border Healthcare Directive and free-movement principles. (curia)

The central European principle can therefore be summarised as:

A Member State may regulate and finance its healthcare system, but its cross-border reimbursement and authorisation rules cannot unnecessarily or disproportionately prevent patients from obtaining medically necessary healthcare in another Member State.

At the same time, reimbursement litigation and medical-negligence litigation must be kept separate. The former is heavily shaped by EU social-security and free-movement law; the latter is primarily a private-international-law and national civil-liability question.
