Abstract
Today, the interaction between health care providers and payers is often manual, error prone and retrospective when it could be done more automatically and accurately in real time. It is often episodic, and it could be a far more efficient process if provider and payer information systems were able to share data electronically. This is yet another opportunity for interoperability, so CMS has established API and data exchange rules for its payers. Payers have also recognized the potential benefits for them and their customers and have worked collaboratively to identifying the potential of FHIR to transform their business processes, particularly as they connect with providers.
