Health Insurance Portability and Accountability ACT (HIPAA)

The Health Insurance Portability and Accountability ACT (HIPAA), passed in 1996 in the U.S., requires millions of healthcare entities who electronically transmit data to use EDI in a standard HIPAA format.

HIPAA EDI is a set of data transmission specifications strictly governing how to electronically transmit sensitive data from one computer to another. It defines the different types of covered transactions and stipulates the exact format for each transaction record.

Its intent is to reduce the hundreds of healthcare data formats previously in use to just one, universally implemented healthcare data standard. This uniformity greatly increases the portability and accessibility of health-related information and slashes administrative costs associated with managing a previously clunky process.
