Why Doesn’t French Health Insurance Reimburse the Full Cost? Understanding the “70% Rule” and Mutuelles

One of the first things many people hear when researching healthcare in France is that the French healthcare system reimburses 70% of medical costs. It sounds reassuring, but many newcomers are surprised after their first doctor’s appointment to discover that, despite being registered with Assurance Maladie and presenting their Carte Vitale, they still have part of the bill to pay.

The reason is simple: the famous “70%” is one of the most misunderstood figures in the French healthcare system.

It does not mean that the French state automatically pays 70% of every medical bill. Instead, reimbursement is calculated against an official reimbursement basis, known as the base de remboursement, or BR. The amount you ultimately pay depends on the treatment, the healthcare professional, the fees charged and whether you have complementary health insurance, commonly known as a ‘mutuelle’.

Does French Health Insurance Always Reimburse 70%?

No. Different types of healthcare are reimbursed at different rates.

Many GP and specialist consultations are reimbursed at 70% of the official reimbursement basis, while many paramedical treatments such as physiotherapy are reimbursed at 60%. Certain medicines may be reimbursed at 65%, 30%, 15% or 100%, depending on their recognised medical benefit.

Hospital treatment in approved establishments is commonly reimbursed at 80% of the official tariff, although some situations qualify for 100% reimbursement. Certain long-term medical conditions, known as Affections de Longue Durée (ALD), can also qualify for 100% reimbursement of eligible care related to the condition.

However, 100% reimbursement does not necessarily mean that every euro charged by a healthcare provider will be covered. The key point is that reimbursement percentages apply to the official reimbursement basis, not necessarily the amount shown on your invoice.

What Does the “70% Rule” Actually Mean?

Consider a consultation with a Sector 1 GP who is your declared médecin traitant.

With an official tariff of €30, Assurance Maladie calculates its reimbursement at 70%, giving €21. A €2 participation forfaitaire is then deducted, meaning the actual reimbursement is €19.

The remaining €9 is the ticket modérateur. Depending on your complementary insurance, your mutuelle may reimburse some or all of this amount. If your doctor charges more than the official tariff because they are permitted to apply dépassements d’honoraires, Assurance Maladie still calculates its reimbursement using the official tariff. Whether the additional fees are covered depends on your mutuelle.

This is why two people receiving the same treatment can ultimately pay different amounts.

Why Do I Still Receive a Medical Bill?

Your remaining bill can contain several different elements.

These can include the ticket modérateur, fees charged above the official tariff, the €2 participation forfaitaire, and medical franchises applied to certain medicines, paramedical treatments and medical transport.

The current franchises include €1 per box of reimbursable medication, €1 per paramedical act and €4 per qualifying medical transport journey, subject to statutory limits. Most responsible complementary insurance contracts cannot reimburse certain statutory contributions, including the €2 participation forfaitaire and medical franchises.

This is why even people with comprehensive health insurance can still have small amounts left to pay.

How Does Hospital Reimbursement Work?

Hospital treatment follows different rules from a standard doctor’s appointment.

In a public hospital or approved private clinic, Assurance Maladie commonly reimburses eligible hospital charges at 80% of the official tariff. However, this does not necessarily cover every cost associated with your stay.

Patients may also have to pay the forfait hospitalier, which contributes towards accommodation and maintenance costs. Since March 2026, this is €23 per day in hospitals and clinics and €17 per day in psychiatric departments, unless an exemption applies.

Additional costs can include a private room, television or telephone services, comfort expenses and specialist fee overruns. Whether these are covered will depend on your complementary insurance.

What Does a Mutuelle Cover?

A mutuelle works alongside Assurance Maladie rather than replacing it.

After the public healthcare system has made its reimbursement, your complementary insurer can reimburse some or all of the remaining eligible costs according to your policy. Depending on your level of cover, this can include the ticket modérateur, specialist fee overruns, hospital costs, dental treatment, optical care and hearing aids.

The 100% Santé system can also provide full reimbursement for certain eligible optical, dental and hearing products when the scheme’s conditions are met. However, choosing products outside the regulated 100% Santé baskets can still leave you with a significant amount to pay.

What Do 100%, 150% and 200% Mutuelle Cover Mean?

This is another common source of confusion.

If a policy offers 100%, 150% or 200% BR, these figures do not mean the insurer pays that percentage of your actual medical bill. Instead, they refer to the maximum combined reimbursement calculated against the official Base de Remboursement. This generally includes the amount already reimbursed by Assurance Maladie.

For example, a policy offering 150% BR could provide combined reimbursement of up to 150% of the official reimbursement basis, subject to the policy terms.

This can be particularly useful when seeing specialists who charge above the official tariff.

Do You Need a Mutuelle?

Not necessarily, but many residents choose one to reduce their exposure to healthcare costs.

Private-sector employers generally have to offer employees complementary health insurance and contribute at least 50% of the cost, subject to certain exemptions. For retirees, self-employed people and many expats, taking out a mutuelle is generally a personal decision.

The question is therefore not simply whether you need one, but whether you are comfortable paying the costs that remain after Assurance Maladie has reimbursed your treatment.

For routine healthcare these costs may be relatively modest, but hospital treatment, dental care, optical expenses, hearing aids and specialist fee overruns can quickly make comprehensive cover more valuable.

How Do Assurance Maladie and a Mutuelle Work Together?

Once your healthcare arrangements are established, the process is usually straightforward.

After presenting your Carte Vitale, Assurance Maladie processes its reimbursement. If your mutuelle is connected through the Noémie system, the reimbursement information can then be transferred automatically to your complementary insurer.

The mutuelle applies the benefits provided under your contract, often without you needing to submit additional paperwork.

The tiers payant system can also reduce the amount you need to pay upfront, although partial tiers payant does not necessarily mean that all costs are covered.

How Should Expats Choose a Mutuelle?

Choosing complementary insurance is not simply about finding the cheapest monthly premium.

Consider your likely healthcare needs and look carefully at specialist fee-overrun cover, hospital benefits, private-room allowances, dental and optical reimbursement, hearing-aid cover and access to the 100% Santé scheme.

A broker with experience working with expats can also help explain the differences between policies and identify cover appropriate to your circumstances.

Understanding the “70% Rule”

The biggest misconception about French healthcare is that one percentage can explain the entire system.

In reality, reimbursement depends on the treatment, the official reimbursement basis, the healthcare professional, the fees charged and your individual circumstances.

A mutuelle can then cover some eligible costs left after Assurance Maladie has paid its share, although certain statutory contributions remain payable. Rather than asking whether France reimburses 70% or 100%, the more useful question is: how much will I actually receive from Assurance Maladie and my complementary insurance, and what will I have to pay myself?

That is the figure that ultimately determines what your healthcare will cost.
