Frequently Asked Questions About Electronic Transaction Standards Adopted Under HIPAA. What standards were chosen?


ANSI ASC X12N standards, Version 4010, were chosen for all of the transactions except retail pharmacy transactions. The choice for the retail pharmacy transactions was the standard maintained by the NCPDP because it is already in widespread use. The NCPDP Telecommunications Standard Format Version 5.1 and equivalent NCPDP Batch Standard Version 1.0 have been adopted in this rule (health plans will be required to support one of these two NCPDP formats).
