Change Healthcare announced an expansion of the self-service resources it offers developers to use application programming interfaces (APIs) at scale to bring new healthcare innovations to market. Additionally, this enhanced experience enables payers to have an easy to integrate solution that helps comply with the pending CMS Interoperability Rule which goes into effect on July 1, 2021. The Change Healthcare Marketplace now provides developers access to a portfolio of over 70 clinical, financial, operational, and patient experience API products that power over half a billion healthcare transactions annually. Now, to speed their time to market and improve their ability to scale, developers have self-service access to extensive technical documentation and tutorials, can try out APIs in a robust testing and implementation sandbox, and can engage with other developers via the Change HealthcareDeveloper Community. Payers, providers, and healthcare technology vendors agree that APIs are mission-critical to their business strategies. But many lag behind in their consumption and development of APIs, according to a recent research study commissioned by Change Healthcare and conducted by ENGINE Insights. These enhancements will help healthcare stakeholders accelerate and scale their use of this transformative technology to deliver a better digital healthcare consumer experience,and address future connectivity needs.
