Lets first start by examining the two namely what is EDI and what are HIPAA standards after which we will proceed to integrate the two.
EDI – stands for Electronic Data Interchange. These are standards provided by IETF(Internet Engineering Task Force) and deal with document handling data flow between the parties that deal with the data transmission , data being transmitted electronically or physically. Initially developed for the automotive industry EDI has been made technology independent as well as communication technology independent.
HIPAA– Stands for Health Insurance Portability and Accountability act is a legislation active in United States which safeguards medical information of individuals. Split up into HIPAA 1-V the parts that are relevant are HIPAA II which specifically deal with national standards for processing electronic healthcare transactions
Thus HIPAA II deals guidelines regarding Identification, EDI standards, Privacy Rules, Security Rules and Enforcement of these rules.
Identification – Each of the entities eg individuals, employees, health plans and providers have a unique 10 digit number.
EDI Standards – Electronic Transactions are standardized when used by entities which are parts of the chain example health care providers, physicians and clearing houses.
Privacy Rules – National standards to protect the patient health information.
Security Rules – Sets standards for Patient data security.
Enforcement Rule – Sets rulesets for HIPAA security violations.
HIPAA EDI standards
EDI X12 is a data format based on ASC X12 standards. Mostly X12 is used to interchange data between two or more partners, organizations or companies.
Due to the industry being very fragmented with various data formats it was better to come out with a single format that would do away with this very issue The EDI rules govern the way data is transmitted from one computer to another.
EDI X12 is a data format based on ASC X12 standards. Mostly X12 is used to interchange data between two or more partners, organizations or companies. HIPAA uses the X12N standards split up into subcommittees which deal with the following – X12C Communications & Controls, Finance, Transportation, Technical assessment, Supply Chain, Insurance.
Example of a EDI X12 file.
When EDI is used there are strict rules as to where the formatting is. These rules will define where the element is in a file. Whenever an EDI translator reads a file it will know where exactly to find the elements in the file. Then, that data will be fed into the receiver’s order entry system in the proper internal format without requiring any manual order entry.
Example of a Purchase order and the corresponding EDI files.
In the EDI language, a single business document, such as a purchase order, invoice or advance ship notice, is called a “transaction set” or “message.” And, a transaction set is comprised of data elements, segments and envelopes.
Data Elements – These are the individual items of information in the document.
Segments – Data Elements are combined into segments. Eg similar data elements.
Envelopes – EDI uses three envelopes to house transaction sets. Transaction set, Group of transaction set placed in a Group envelop and finally the Interchange Envelope which comprises of all envelops being sent from one sender to one receiver are placed in an interchange envelope.
