EDI Transactions

PilotFish Delivers Broad Support for All X12 Standards and HIPAA EDI Transactions


A surge in the number of end-users such as payers, providers, pharmaceutical, and medical device industries, and others is anticipated to fuel the demand for EDI services and solutions. Healthcare payers also use EDI for the evaluation of insurance claims before their payment settlement, risk analysis, and prevention and detection of fraudulent claims to provide rapid services through collaborating with providers in order to gain competitive advantage.

The EDI X12 format was developed by ASC X12 (Accredited Standards Committee X12), and primarily serves the US industry. The X12N Insurance subcommittee of X12 establishes the standards that are used for health insurance transactions in the US. The eiConsole for Healthcare X12’s Data Mapper comes equipped with an EDI Format Builder. Within the data mapper, users need only select from the EDI Format Builder’s drop-down menu to choose the transaction they want to work with. It is a simple process taking just seconds to read in the transaction. Once the transaction set is loaded, users can begin the smooth drag & drop mapping process in the eiConsole for X12 Bundle.

EDI X12 usage involves message syntax and standard, messaging protocol, and transports.

EDI messages consist of an envelope and a hierarchical series of structural elements. PilotFish’s graphical Automated Interface Assembly Line process at the Data Mapper stage using XML syntax makes it very easy to transform and exchange EDI formats by employing XSLT, the W3C standard language defined to enable transformations of XML documents.

The key EDI X12 transaction sets specified by HIPAA include:

(Note: As of 2012, healthcare providers must be compliant with version 5010 of the HIPAA EDI standards.)

 

EDI Message Basics

EDI messages begin with a header identifying the kind of message being sent. That header is followed by a number of components called segments. These are provided in the sequence specified by the message specification, e.g., EDI 837 Specification. Each segment is further divided into fields, which contain a value using a data type specified by the standard.  Messages, segments, and fields are delimited by special characters which vary depending upon the standard. Fields may be further subdivided into components and subcomponents.  A single segment or groups of segments can repeat (these are called loops in the X12 world), allowing complex structures to be communicated.

Segments begin with a 2 or 3 letter code like ST or ISA. Some segments are mandatory, while some are not. The mandatory segments of X12 are:

  • ISA – interchange header that contains information about the sender and recipient.
  • GS – functional group header segment of a set of X12 documents of the same document type (transaction set). Includes information (codes) about the functional group: sender, recipient, and date/time.
  • ST – transaction set header segment marking the start of a transaction set.
  • SE – transaction set trailer segment marking the end of a transaction set.
  • GE – functional group trailer segment of the same transaction set. Includes information on the number of functional groups and control group number: marks end of a group of transaction sets.
  • IEA – end of the interchange including interchange control reference number and information on the number of functional groups.

The hierarchical structure of an EDI message enables transaction sets/messages and groups to be batched. Even if an interchange contains only one transaction set/message and only one group, that interchange is structured with the same basic structural elements that it would have if it were batched, with the exception that there would not be multiple transaction set/message or group elements.

By embedding its deep knowledge of the X12 schemas and standards within the eiConsole and eiPlatform product suite, PilotFish delivers breakthrough productivity-boosting features that strip away the technical complexity of parsing, validating, mapping and producing EDI X12 files.
