ICD-10 code Updates, Effective October 1, 2016

October 4, 2016

ICD-10 Testing Through EDI

CMS issued an updated list of additional ICD-10 codes, effective October 1, 2016. This update provides instructions to submitters on how to test the new ICD-10 claims through EDI.

  • The submitter must ensure that the ISA15 data element of the Interchange Control Header Segment of the submitted file is set to 'T' (for test files).
  • The submitter must ensure that their own processes correctly detect the presence of a 'T' in the ISA15 data element of the Interchange Control Header Segment of the resulting outbound X12 files (for example, 277CA and 835), so that they do not inadvertently pull test outbound files into their production processes.

All claim types can be tested in the ICD-10 Testing Environment, including Professional and Institutional Claims.
