Invalid Event Sequence (BWC EDI Errors)
Invalid Event Sequence results in filer submitting an EDI transaction outside sequencing guidelines. You should check the claim in WCAIS or the last ACK received to determine the current claim status then use the Relaxed Rules document, Claim Status Reference Sheet, and the Event table for further sequencing rules. Also refer to section 4 of this document for next steps. 
Filer should always consult the WCAIS claim status prior to submitting a transaction to be sure the transaction will accept. The claim status returned to the filer within the ACK upon acceptance of a transaction.
