Draft — pending verification
This reference entry has not yet been verified against its authoritative source (Original definitions; regulatory facts to be verified against CMS-0057-F (89 FR 8758) and X12/HL7 documentation). Do not rely on it for production configuration until this notice is removed.
In more depth
In the X12 278 the appeal enters as certification type 1 (immediate) or 2 (standard) referencing the original certification. Appeal overturn rates are among the CMS-0057-F public metrics, and persistently high overturn rates are read — by regulators and plaintiffs alike — as evidence the initial determinations were wrong.
