The Electronic Healthcare Network Accreditation Commission (EHNAC) is a voluntary, self-governing standards development organization (SDO) established to develop standard criteria and accredit organizations that electronically exchange healthcare data. These entities include electronic health networks, payers, financial services firms, health information exchanges and e-prescribing solution providers.

EHNAC was founded in 1993 and is a tax-exempt 501(c)(6) nonprofit organization. Guided by peer evaluation, the EHNAC accreditation process promotes quality service, innovation, cooperation and open competition in healthcare.
