Has anyone that is using the HIPAA Accelerator in BizTalk 2002 figured out a way to check whether the data comes from the Subscriber Data or the Patient Data. Since all of the fields from the Claim Level on down are setup twice, we are having the dickens of a time retrieving which value actually exists in the file to be translated. (Such as Rendering Provider) We are mapping to NSF3.1. We have tried several different ways of determining which level should be used, but keep getting just one or the other, usually the wrong one. Any suggestions would be appreciated.
