You have just received a dentist’s bill or an optical quote, and you are looking for how to send it to your Pacifica mutual insurance from Blois. The reflex might be to go through your online bank Crédit Agricole, but this channel no longer accepts health documents. Pacifica has switched to a dedicated portal that centralizes all procedures related to supplementary health insurance.
Health Client Area: the only channel for your Pacifica mutual documents

Since the shift to “fully digital,” health documents no longer go through banking messaging. Attachments sent via your online Crédit Agricole space are systematically rejected or redirected. The portal ca-prestations-sante.fr replaces all old channels.

This portal, called Health Client Area, combines several functions in one journey. You can upload supporting documents (PDF invoices, photos of quotes), view the history of your submissions, and track the status of each request.
If you haven’t created your account yet, simply click on “Create an account” from the homepage of the portal. Have your member number ready, which is found on your third-party payment card or on your benefit statements. You will find more details on the address of the Pacifica mutual in Blois and the various ways to contact the management service.

Contacting Pacifica by phone from Blois: which number according to your need

Pacifica does not have its own agency. Your contact remains your Crédit Agricole advisor in Blois for any questions related to your contract: adding a beneficiary, changing the plan, requesting a quote. However, calls related to health reimbursement management are handled by dedicated platforms.
Do you need to reach the health mutual service? The number to call is 09 77 40 50 00, charged at the price of a local call. This service is available from Monday to Friday, from 8 AM to 6 PM.
For auto or home insurance claims (which are not covered by the mutual but by property insurance), there is a separate toll-free number: 0 800 810 812, available 24/7. The two lines serve different purposes, and calling the wrong one delays the processing of your request.
When to go through the Crédit Agricole agency in Blois
Your local agency remains the right contact in three specific cases:
- You want to subscribe to a new guarantee or modify your Pacifica health mutual contract (change of coverage level, adding a dependent).
- You need a coverage certificate for an employer or a social organization.
- You are considering cancellation and want to compare options before starting the process.
Outside of these situations, the online portal and the phone platform handle almost all requests more quickly than an in-person appointment at the agency.
Sending a paper letter to Pacifica: postal address and precautions
Some documents are not easily digitized, or you prefer to keep a physical proof of sending. The postal address of Pacifica’s headquarters is 8/10, boulevard de Vaugirard, 75724 Paris Cedex 15. All correspondence related to health mutual is centralized there, regardless of your department.
A few precautions can prevent processing delays:
- Include your member number on each document sent, including on the practitioner’s invoices.
- Prefer registered mail with acknowledgment of receipt for complaints or cancellation requests.
- Do not mix health mutual documents with auto or home insurance documents in the same mailing, as sorting services are separate.
Cancellation of the Pacifica mutual: what the law allows from Blois or elsewhere
Since the introduction of the infra-annual cancellation, you can cancel your supplementary health insurance at any time after the first year. The procedure does not depend on your place of residence.
The request can be sent by mail to the Paris headquarters, or directly to your Crédit Agricole agency in Blois, which will forward the cancellation to Pacifica. In both cases, the cancellation takes effect one month after your request is received.
What your new insurer can do for you
If you change mutuals, your new organization is obligated to manage the cancellation with Pacifica. You only need to sign a cancellation mandate. This mechanism, provided by law, avoids double contributions and simplifies the transition.
The main mistake is to cancel before receiving confirmation of the new contract’s effective date. In between, you risk a period without supplementary coverage, which can be costly in case of unexpected care.
Whether you go through the portal ca-prestations-sante.fr, by phone, or by mail, each channel has its own use. The online portal remains the fastest for regular reimbursements. The phone is used to unblock a pending file. Mail remains the recommended route for legal actions such as cancellation. Adapting the channel to the nature of the request is the most reliable way to get a response within a reasonable timeframe.
