It is easy to be cynical. Value-Based Care, MIPS, Meaningful Use, HIE, RHIO, and so many other initiatives have promised to do what seemingly cannot be done: enable the flow of healthcare data among stakeholders. Why will the Patient Access API be any different? 

LexisNexis Risk Solutions believes that our industry is at the transition into an age where interoperability will become meaningful, in that it will drive better healthcare decisions by patients and physicians alike. It will lower costs, improve quality, and remove friction across the silos of care delivery.  At the heart of this transition is a mighty enabling piece of technology called the Patient Access API.

Background – The Electronic Data Interchange (EDI)

It is easy to understand why the data does not flow. Each physician, hospital, pharmacy, or insurance company has their own computer system, often created by different vendors. Until recently, much of the data they owned stayed on paper. There was little incentive to share the data, no standards for doing so, and many legal and financial reasons to keep the data locked up tight.

The first major (and successful) effort to share data among healthcare stakeholders was not called interoperability; it was known as Electronic Data Interchange (EDI). It was not focused on the treatment of healthcare, but the payment of healthcare: Revenue Cycle Management (RCM).  

For years, both payers and hospitals had computer systems to create claims (billing) and adjudicate the claims (accounts payable), but there was no common format or coding, so providers would use their computer to print/fax paper claims that would go to the payers and get typed in. Only the Federal Government could change this. Not only were they the biggest payer in the world (and they still are), but they had the power to create regulation and binding standards. They worked with a standards body called X12 to create a family of standards called 4010 (we now use 5010) that include the familiar formals and resulting data streams of 837 and 835 and others. 

The EDI’s Contribution to Interoperability

The EDI was wildly successful, replacing a river of paper and faxes with electronic transactions.  It greatly improved accuracy, significantly reduced administrative cost, and made possible the expansion and sophistication of the current US healthcare system, which could not operate our current Fee-For-Service approach with the old paper-based process. 

While it took 10 years of work to prepare and the mandate of the government to compel action, the adoption of EDI occurred far faster than most imagined at the start. Within five years, most claims were being moved and processed electronically without human touch; today, nearly 90% of all claims auto-adjudicate and our billing and payment systems are interoperable.

Fast, but not easy, as the hard work to establish and scale the EDI involved armies of RCM personnel (that did not exist at the start), a mountain of published “companion guides” that worked out the needed messy details, enormous expensive changes in the computer software used, the establishment of private professional enabling organizations (such as WEDI), and the creation of a whole new industry (clearinghouses) to solve variations across hundreds of payers and hundreds of thousands of providers.  It was well worth it. Today, even without the government mandate, no payer and only a trivial number of providers could operate without EDI.

But this was interoperability for the payment of healthcare.  What about the much larger and more valuable data sets that are needed for the treatment and the management of healthcare?
