Update - to clarify:
In support of the X12 work on "005010X214 - 277 Health Care Claim Acknowledgement" and the work that WEDI has accomplished regarding the acknowledgements white-paper - I recommend that via the DSMO process, the "005010X214 - 277 Health Care Claim Acknowledgement" transaction be adopted as a HIPAA National Standard by HHS.
I first made this request in 2002 (August 13th to be exact - see request number 708).
Over the years - the need to have a standard claim by claim acknowledgement of acceptance or rejection has become crystal clear.
I receive almost as many formats of acknowledgements as I do payers who receive claims. I have some who do, and others who do not do, 997 transactions. For those who do them, about 2/3rds do them correctly, the other 1/3rd are worthless.
Often, when I receive a 997 - i find that the batch of claims do not actually process into adjudication due to system issues - and I'm often not notified.
In addition to the X12 work on "005010X214 - 277 Health Care Claim Acknowledgement", the work that WEDI has accomplished regarding acknowledgements is very important and I recommend that via the DSMO process, the WEDI Acknowledgement recommendations be moved forward and recommended for adoption as HIPAA National Standards by HHS.
