COSE Benefit Plan Resources
Medical Mutual and the Council of Smaller Enterprises (COSE) have rebranded the COSE MEWA product to be officially called COSE Benefit Plan. This change will help limit confusion in the market surrounding the purpose of the product. Please note, this is only a name change and does not impact the product’s offerings or requirements. It is still a MEWA product.
While we transition cosemewa.com to reflect the new brand and product name, please use this page as your source for all current COSE Benefit Plan materials.
