As part of the introduction of health insurance for private and parastatal sector employees in June 2014, the National Health Insurance and Social Guarantee Fund (Caisse nationale d'assurance maladie et de garantie sociale – CNAMGS) initially entrusted the task of collecting contributions to the National Social Security Fund (Caisse nationale de sécurité sociale – CNSS).

In July 2013, the National Social Security Fund (Caisse nationale de sécurité sociale (CNSS)) launched a programme to improve its information system by integrating the use of biometric cards and e-declarations in its operation. With the biometric card, insured individuals will be able to verify the payment of their contributions, obtain all career and status information, simulate the conditions of their upcoming retirement and collect benefit payments at a kiosk.

In the context of the introduction of mandatory health insurance in Gabon, the government was concerned about social coverage for its economically disadvantaged citizens. It was not politically or socially acceptable to establish health coverage that would exclude a large segment of the population. This raised the issue of the financing of their benefits. An innovative form of financing was thus found - specifically, an indirect earmarked tax referred to as the "mandatory health insurance fee".
