Declaring a Change of Situation

You must inform CPAM of any significant change in your situation (address, professional status, family status) to ensure your health coverage continues without interruption. This declaration can be made online or by written letter.

This page explains how to make this declaration, what information to provide, and offers a ready-to-use letter template, plus a tool to automatically generate your personalized letter.

When should you write this letter?

• You recently changed your address;
• Your professional situation changed (new job, work stoppage);
• Your family situation changed;
• You had difficulty declaring online;
• You need to update your bank details for reimbursements.

In all these cases, a written letter remains a reliable way to update your file.

Required information to include

• Your first and last name and social security number;
• The nature of the change and its date;
• The new information (address, professional status, etc.);
• Documents attached depending on the nature of the change.

The more accurate this information is, your health coverage continues without interruption.
