FOIA VistA

Freedom of Information Act (FOIA) VistA is the "redacted" version of VA Enterprise VistA, released publicly via the Freedom of Information Act. FOIA VistA software and associated material are redacted and may not be fully functional due to missing components. A few of the items that are removed by the redaction process include: hashing and encryption components; and proprietary terminologies such as CPT and GCN_SEQNO. It should be kept in mind as well that some basic functions in FOIA VistA don't work since they rely on custom VA enterprise software for functions such as a Master Patient Index and copyrighted drug information. In spite of this, by and large the majority of functionality expected in an EMR functions well in FOIA VistA.

OSEHRA makes FOIA VistA available through all our distribution channels for transparency and to be able to provide developers and innovators an accurate representation of the software currently executing inside the VA.
