When a doctor announces insulin-dependent diabetes or multiple sclerosis, the financial question arises almost immediately. Treatments can last for years, sometimes for a lifetime. To prevent the cost of care from adding to the burden of illness, Health Insurance has created the long-term condition system, or ALD.
This mechanism allows for 100% coverage of care related to certain serious pathologies. However, it is essential to understand what this “100%” truly covers.
What remains to be paid when you are in ALD
You may have already noticed, on a reimbursement statement, the mention “co-payment”? This is the portion that the patient usually pays (for example, 30% of a consultation). ALD exempts from the co-payment only for care related to the illness and listed in a document called a care protocol.
Let’s take a concrete example. A person with type 1 diabetes consults their endocrinologist, has their glycated hemoglobin measured, and buys their insulin. These actions are included in their protocol: Health Insurance reimburses them at 100% of the Social Security rate.
The same person visits a dermatologist for a skin issue unrelated to diabetes. This care remains reimbursed at the standard rate, with a co-payment at their expense.
However, the Social Security rate is not always what the practitioner charges. If a specialist charges above the standard fees, the difference between the agreed rate and the actual price remains the patient’s responsibility, even in ALD. Medical deductibles (on medications, paramedical acts, and transport) and the daily hospital fee are also not eliminated by the ALD status.
This is where complementary health insurance comes into play. To cover these out-of-pocket expenses, an appropriate mutual insurance makes a real difference, especially for patients followed by specialists in sector 2.

ALD Care Protocol: the document that determines your reimbursements
The care protocol is the cornerstone of the system. It is not enough to be diagnosed to benefit from the exemption. Your primary care physician must write this protocol, which lists the treatments, examinations, and specialized consultations necessary for your pathology. This document is then sent to the Health Insurance medical advisor for validation.
You can find the eligible pathologies by consulting the list of serious illnesses on zone-sante.fr, which details the affected conditions and associated care.
A often overlooked point: only the care listed in the protocol qualifies for the exemption. If your primary care physician prescribes an act related to your ALD but that act was not included in the initial protocol, it may be necessary to update the document. Without this update, reimbursement will be at the usual rate.
Duration and renewal of the protocol
The exemption is not automatically unlimited. The initial duration varies depending on the pathology. For certain stabilized chronic conditions, a renewal will be requested at the end of the term. The primary care physician must then justify that the care remains necessary.
Anticipating this renewal avoids an interruption in coverage. Check the end date indicated on your protocol and make an appointment with your doctor a few months before the deadline.
The conditions on the ALD 30 list: which diseases are concerned
We talk about “30 diseases,” but the term is misleading. The list actually groups categories of pathologies, each of which can encompass several clinical forms. For example, the category “severe forms of neurological and muscular disorders” includes both myopathy and severe epilepsy.
Here are the major families of diseases on this list:
- Severe cardiovascular diseases, such as disabling stroke, severe heart failure, coronary disease, or chronic arterial diseases with ischemic manifestations.
- Metabolic and endocrine diseases, including type 1 and type 2 diabetes, cystic fibrosis, or severe chronic respiratory failure.
- Cancers, blood diseases (hemophilias, hemoglobinopathies), and severe primary immunodeficiencies, including HIV infection.
- Severe neurological and psychiatric disorders: multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, severe forms of epilepsy, paraplegia.
- Chronic kidney diseases (severe chronic renal failure), active chronic liver diseases (hepatitis B or C, cirrhosis), and progressive rheumatoid arthritis.
Severe hypertension has been removed from the list, even though the term “ALD 30” remains in common usage. Patients already covered before this removal have retained their rights under certain conditions.

ALD outside the list and multiple pathologies: beyond the 30 diseases
Some serious diseases are not on the official list but may still qualify for 100% coverage. This is referred to as “off-list” ALD (sometimes called ALD 31). The condition: the treatment must be prolonged and costly, with a predictable duration exceeding six months.
A third category exists for patients with multiple conditions that, taken individually, would not justify the exemption but whose combination results in a disabling state. This is ALD 32, known as “multiple pathologies.”
What the type of ALD changes concretely
For the patient, the reimbursement mechanism works the same way: exemption from the co-payment on care related to the affected conditions, within the limit of the Social Security rate. The difference comes at the time of the request, as the medical advisor examines off-list files more closely.
Recent developments in ALD coverage
The system is not static. Recent regulatory adjustments have changed the reimbursement level of certain medications, even for patients in ALD. Some treatments previously fully reimbursed are now only reimbursed at a reduced rate, which mechanically increases the out-of-pocket expenses.
Other care related to ALD retains the principle of 100% coverage of the agreed rate. These developments emphasize the importance of carefully checking one’s care protocol and having complementary health insurance that covers any potential gaps.
The ALD status remains a major safety net for patients with serious chronic illnesses. But it does not exempt from vigilance: reading your protocol, monitoring your renewal date, and choosing a mutual insurance that covers excess charges and deductibles are part of the care pathway as much as the consultations themselves.
