This article describes a hotfix that supports 999 functional acknowledgements and 277CA for HIPAA 5010 Errata in Microsoft BizTalk Server 2010.

Starting from January 1, 2012, the United States Centers for Medicare & Medicaid Services will accept only 999 and 277CA acknowledgements for 5010 transactions. However, this restriction is not required by HIPAA. Additionally, the website no longer accepts 997 acknowledgements. This hotfix enables support for these requirements in BizTalk Server 2010.

More Information

The hotfix package contains the following updated files:

  • Microsoft.biztalk.edi.messagecore.dll

  • Microsoft.biztalk.edi.pipelinecomponents.dll


The file contains newly added schemas that support the 999 and 277CA acknowledgements. After you apply the hotfix, a Use 999 Acknowledgment Instead of 997 option is available when you use the EDI disassembler component to create a new pipeline. Additionally, an Override997With999 setting is listed in the configuration setting of the pipeline. 

Known issues

  • When you use the EDI receive pipeline (EDIReceive) in a receive location, no Override997With999 option appears when you configure the pipeline. If you want to generate 999 acknowledgements, create a custom receive pipeline, set the Use 999 Acknowledgment Instead of 997 option to true in the EDI disassembler, and then deploy the pipeline to use the functionality that generates 999 acknowledgments. You can then configure the Override997With999 option to true or false in the configuration setting of the pipeline to enable or disable generating 999 acknowledgements.

  • If you check the Extended Validation check box in agreement, 999-acknowledgement messages are suspended in the EDI send pipeline.

  • When you set the transaction type to 277_A in the envelope settings, the GS1 value is not updated to HN.
