Reader Question: I have a long-term illness and benefit from 100% coverage under France’s health system. Do I still need supplementary (mutuelle) health insurance?
While France does provide 100% coverage in cases of long-term illness (ALD) for treatment related to the condition, this coverage is based on the official social security reimbursement rates.
Other medical needs (such as visits to a dentist or ophthalmologist) are reimbursed at the usual rates. This means you should not be too quick to cancel your supplementary insurance.
It is also important to note that “100% coverage” does not mean all costs are fully paid.
Certain expenses, such as additional fees charged by some doctors on top of the standard state tariffs, the €2 medical contribution, franchises médicales (small levies on boxes of medicines and certain care procedures), and hospital daily charges, remain payable by the patient unless covered by a mutuelle.
In which cases am I 100% covered?
In the case of a long-term illness (ALD), patients can receive reimbursement up to the maximum limit set by Assurance Maladie.
This means they are exempt from the usual patient co-payment for care related to their condition. The list of these long-term illnesses covered can be found here.
Your doctor will prepare a treatment protocol requesting 100% coverage once you have been diagnosed with one of the long-term conditions eligible for this scheme.
These conditions include disabling stroke, bone marrow failure, Parkinson’s disease, and many others.
In many cases, the tiers payant system applies, meaning you may not have to pay upfront for care related to your long-term condition, although this depends on the healthcare provider.
ALD patients can also benefit from enhanced coverage in the case of pregnancy. Medical examinations that form part of mandatory pregnancy monitoring are fully covered by the French health insurance system from the beginning of pregnancy until 12 days after delivery.
In cases of high-risk pregnancy or serious pathology, additional examinations or ultrasounds may be prescribed and covered.
From the fourth month of pregnancy, certain dental check-ups for oral health are covered, as well as a wide range of general medical care, particularly from the sixth month onwards.
Childbirth costs are also covered for up to 12 days (excluding personal comfort options such as a television or a private room). If you live more than 45 km from a healthcare facility, accommodation in a hospital hotel for up to five days may also be reimbursed.
Care for people with long-term illnesses is divided into two categories.
The first includes care directly related to the condition, which is covered at 100% (based on Social Security tariffs). This includes:
Consultations and medical procedures
Prescribed medication
Nursing and physiotherapy care, biological tests, and medical devices
The second category includes care that is not related to the long-term condition.
In these cases, reimbursement is at standard rates, often 70% for doctor visits, medication at 65%, 30% or 15%, and nursing care, physiotherapy, biological tests, and medical devices at around 60%.
For example, if you have been granted 100% coverage due to coronary artery disease, treatment to stabilise the condition and follow-up consultations with a cardiologist will be reimbursed at 100% of the Social Security rate, often with no upfront costs where third-party payment applies.
However, if you need to visit a dentist, or consult an allergist or an ophthalmologist, the national health system will only cover part of the cost.
You will usually have to pay the remaining share, and possibly any excess fees.
Do I still need a mutuelle?
In most cases, yes. Even with 100% ALD coverage, you may still face significant out-of-pocket costs:
Additional fees charged by many specialists
Hospital daily charges (around €20–€23 per day)
Costs for a private room or other comfort services
Healthcare not related to your long-term condition (dental, optical, hearing, etc.)
A supplementary health insurance policy (mutuelle) can cover all or part of these remaining costs, depending on the level of cover you choose.
