Evergreen Users Billing 837 Claims
With the new Evergreen system rollout, previous authorizations with a prefix of “EIS” have been replaced by new authorizations with a prefix of “LTS.”
Our current Electronic Data Interchange (EDI) 837 file was developed with a max of 15 characters for authorization IDs. Some LTS authorization IDs were generated with a max of 17 characters. When submitting 837 claims, providers are reporting that the last two characters of the 17-character authorization ID are getting cut off, resulting in denied claims with the “UM not found” edit.
