Abstract As the Universal Health Insurance Plan (RAMU) is gradually being implemented in Mali, community‐based health insurance (CBHI) —considered one of the pillars of this programme— must innovate to meet the challenge of universal health coverage. An experimental CBHI was tested in central Mali between 2017 and 2021. This innovative CBHI professionalizes and organizes risk sharing on a larger scale than before, moving from municipalities to circles (departments). A mixed‐method study was carried out in the Mopti region to assess the acceptability of this innovation among CBHI elected representatives. In April 2021, 118 questionnaires were administered to CBHI elected representatives, followed by 43 qualitative interviews from the same sample in October 2021. Sekhon et al. (2017) developed an approach outlining seven dimensions of acceptability (attitude, burden, values, coherence, opportunity costs, perceived efficiency, and personal effectiveness), which was used as a conceptual model for data analysis. The results obtained by factor analysis indicate that more than half of individuals (58%) reported above‐average acceptability. Elected representatives feel well supported in their activities by the Technical Union of Malian Mutuality (TUM), the umbrella organisation of CBHI. They show some confidence in their ability to perform their duties effectively despite varying levels of commitment that often fall short of expectations and needs, which they justify by their volunteer status. Elected representatives note that the system is very effective despite the nonoptimal conditions linked to the prevailing insecurity. The new CBHI is highly advantageous for the population in terms of content, financial, and geographical access. Professionalisation is an unavoidable condition for the performance of the innovation, as well as the new community assembly. However, elected representatives are concerned about the sustainability of this CBHI and rely on the State and its partners to assume responsibility. The TUM will play an essential role in continuing its support and fulfiling its functions as a delegated management organisation within the framework of the RAMU.
