Per the CDC guidance inactive CVX codes should be used to record
-An administrable vaccine formulation that is no longer available for patient administration, but can be found in historical patient records OR
-A historical record of a vaccine administered where the exact formulation is unknown
Inactive codes are missing from value sets for CMS117, CMS127 and CMS147. This requires provider to record clinically inaccurate data (more specific than is known from the historic record) in order to meet these measures.
