Which of the following standards is NOT supported by Bridges?

The correct answer is HL7, as this standard is not supported by the Epic Bridges tool. Bridges primarily focuses on specific standards that are critical for interoperability in healthcare data exchange. X12 is widely used in electronic data interchange (EDI) in healthcare, allowing for transactions such as claims and eligibility checks. NCPDP is a standard specifically designed for electronic healthcare claims and pharmacy transactions. Direct, another standard supported by Bridges, facilitates secure email communications among healthcare providers.

HL7, while a major standard for the exchange of clinical and administrative data in healthcare, is often considered a different category of standards compared to those typically utilized by the Bridges tool for integration. Therefore, among the options listed, HL7 is indeed the standard that does not align with the focus and capabilities of Bridges. This distinction highlights the different roles that various standards play in the healthcare interoperability landscape.
