X12 Recommendations to NCVHS
X12 has submitted the first two in a series of recommendations related to advancing the version of already adopted and mandated transactions and proposing additional transactions for adoption.
Based on industry feedback, X12 is using a phased approach for the recommendations rather than presenting the entire catalog of adopted and mandated transactions at once. Each recommendation will cover a set of logically grouped transactions and will include supporting information that will assist reviewers as they look at the functionality enhancements and other revisions.
