The goal is to create an open, widely agreed Health Claims data Exchange Specifications as a public good that can be adopted. Specifications in this context refer to the blueprint of each aspect of the envisioned claims network and are fundamental to the working of the network. They have been carefully designed to be open to support technology and vendor neutrality, evolvable over a period of time thereby helping adapt to changing needs, enable and not restrict innovation or inclusion. The current version of the specifications is widely evaluated for the cashless claim use case, and different volunteers are working on the evaluation for other use cases, such as reimbursements and OPD. More use cases are being planned for the future.
