An employee changing jobs, a freelancer starting their activity, a retiree whose optical or dental needs are increasing: each situation imposes different considerations when choosing a health mutual. The common reflex is to compare prices, but the monthly rate says almost nothing about the actual quality of a contract. It is better to start from what one actually spends on care to build a solid coverage.
Transfer of costs to mutuals: what changes concretely from 2027
Several decrees published on August 22, 2026, organize a shift of expenses from Health Insurance to complementary health plans. Four areas are directly affected: dental care, medical devices (glasses, hearing aids), certain medications with low or moderate medical service rendered, and health transport.
The participation left to the patient (and thus their mutual) increases from 35-45% to 50-60% on dental care and certain medical devices. The French Mutuality estimates this transfer to be around 1.5 billion euros in additional expenses for complementary health plans.
This is a structural change, not a marginal adjustment. If you choose a mutual today with minimal dental or optical guarantees, you risk finding yourself with a much higher out-of-pocket expense in less than two years. A contract taken out now must already anticipate these transfers. Check that the reimbursement caps on these areas are not locked at too low a level, as mutuals will likely adjust their pricing grids and guarantees.
To compare the available offers and their levels of coverage on these sensitive areas, you can consult lamutuelledesante.fr, which references different plans on the market.
Rising contributions: reading a health mutual quote without getting trapped
The rates of complementary health plans have been continuously increasing since 2020, with a marked acceleration in recent years. This trend is not an accident: it reflects both the inflation of medical acts and the cost transfers mentioned above.
When you receive a mutual quote, the monthly amount stands out. But two contracts at the same price can cover very different realities. Here are the points to systematically check:
- The reimbursement method: some contracts display a percentage of the conventional rate (100%, 200%), while others show an annual flat fee in euros. A “200% in dental” does not cover the same thing as a flat fee of 600 euros per year if you need a crown
- The waiting periods: for hospitalization or dental care, some mutuals impose several months of waiting before any coverage. A cheaper contract with six months of waiting on dental prosthetics can end up costing much more
- The annual revaluation clause: check if the contract provides for automatic indexing of contributions and, above all, if the guarantees follow the same trend. A contribution that increases without raising the caps degrades your coverage year after year
- The responsible contract mechanism: the majority of mutuals market so-called “responsible” contracts, regulated by law, which cap certain reimbursements (notably excess fees) in exchange for tax benefits. Check that the contract has this mention
Health mutual guarantees: three areas to calibrate according to your profile
Rather than reviewing all the lines of a guarantee table, let’s focus on the three areas where the differences between contracts are most significant and where calibration errors are the most costly.
Hospitalization and excess fees
A hospital stay with a surgeon in sector 2 can generate excess fees of several hundred euros. The reimbursement of excess fees is the most discriminating factor between two mutual contracts. A contract that reimburses 100% of the conventional rate does not cover any excess. You need at least a contract that shows 200% or more on this item, or a sufficient dedicated flat fee.
Optics and hearing aids
With 100% Health, class A equipment (glasses, hearing aids) is fully covered. However, as soon as you step outside the regulated basket for high-end progressive lenses or specific frames, the out-of-pocket expense rises quickly. Feedback on this point varies by brand and region, but an annual optical flat fee that is too low remains the most common trap in entry-level contracts.
Dental care and prosthetics
This is the area where the cost transfer planned for 2027 will have the most impact. A dental implant not covered by 100% Health can represent an out-of-pocket expense of several hundred euros. Look at the annual cap in dental care and not just the displayed percentage.
Comparing mutual offers: a concrete method in three steps
You do not compare mutuals like you compare phone plans. Price alone is not enough, and guarantee tables use different units from one insurer to another.
The most reliable method starts from your actual expenses. Retrieve your reimbursement statement from your Ameli account for the last twelve months. Identify the three areas where your out-of-pocket expense has been the highest. These are the lines to compare first in the quotes.
Then, request at least three quotes from insurers with different profiles (traditional mutual, general insurer, online broker). Compare the reimbursements on your three priority areas, not the total guarantees. A contract that excels in your real needs is better than a “complete” contract that spreads coverage thinly.
Finally, read the cancellation conditions. Since the law of July 14, 2019, cancellation is possible at any time after one year of membership. This flexibility allows you to correct a poor choice without waiting for the annual deadline, but it does not exempt you from making a good choice from the start: changing contracts sometimes involves new waiting periods.
The cost transfer scheduled for 2027 will reshape the balance between contributions and reimbursements for dental care, optics, and medical devices. A contract chosen solely based on today’s price risks becoming insufficient quickly. Starting from your actual expenses, checking the caps by area, and anticipating regulatory changes remains the most solid method to avoid unpleasant surprises.
