Complementary health solidarity: helping a loved one in his or her efforts

When health care expenses worry a loved one, first checking his/her rights can avoid giving up a consultation. The Solidarity Health Supplement, often called C2S or CSS, is a device to be examined with Sickness Insurance. The Helper can support the steps while allowing the person to keep control of his/her file.

What is the purpose of the Solidarity Health Supplement?

It pays the additional share of certain health expenses according to the rules of the scheme. Its access depends on the resources and the situation of the home. Participation can be requested according to the situation. Thresholds change: check the criteria in force with your caisse rather than using an old table of amounts.

The sickness insurance specifies in particular the importance of the coordinated care route, the use of contracted professionals and an up-to-date Vital Card or a certificate of entitlement. Benefits outside the prescribed framework may leave a fee to be paid. Ask the professional for an estimate or explanation before an expenditure whose care is uncertain.

Preparing the process with the loved one

Check the official information together and ask the caisse what approach corresponds to their situation. If assistance is needed for the file, a social worker or a reception point can guide the person. Do not conclude that he or she is eligible from a single monthly income.

  • List the documents actually requested by the organization.
  • Record the filing date and keep the acknowledgement of receipt.
  • Identify the remaining parts to be supplied.
  • Identify who follows the answer, with the close friend's agreement.
  • Enter the deadlines indicated in the decision or letters.

Protecting Personal Information

Helping the process does not require the publication of household resources in a notebook shared by all stakeholders. Keep administrative documents in a suitable location and limit their access. In the common agenda, a task such as "recalling the caisse on Thursday" may suffice.

Do not share the password of the ameli account in the family courier. If the person needs to be represented, ask the organization how to formalize this assistance.

Articulating rights and organization of care

The cost coverage and organization of visits meet two different needs. Once the rights are clarified, the shared planning helps the family prepare appointments and accompaniments. support for family caregivers presents other useful interlocutors.
