ICD9
The ICD9 conversion map uses the combined files for diagnostic and surgical codes v22icd9_file1.txt and v22icd9_file2.txt (within v22_icd9[1].zip) available from CMS (http://www.cms.hhs.gov). For more information about this code list, see the External Code Source section of Washington Publishing HIPAA 005010 Implementation Guide.
Input
The input format is positional and is formatted as follows:
| Column | Data-type | Start Position | Maximum Length |
| Code | string | 1 | 5 |
| Description | string | 6 | 255 |
Notes
The fields are linked directly to fields on the Output side of the map. There is logic on the fields to trim excess “white space,” if necessary.
The TempLink in the LinkingRecord group is present to ensure that the extended rules (on the Output side of the map) which are responsible for writing out the schema namespaces and the Sterling B2B Integrator version attributes for the SI_RESOURCES document element are executed.
