Hints for Successful EDI Bill Submissions
ESIS may reject bills if the providers' Tax ID Number (TIN) is not in our system. Please verify that the TIN you are submitting is on file with ESIS. This is particularly important for providers using multiple TINs.
Submit EDI bills with the providers full and proper name and National Provider Identifier (NPI) number. To apply for an NPI number, go to https://cms.hhs.gov.
If possible, verify the proper Claim Number prior to transmission.
Information on how a health care provider can provide the claim number and how to submit the claim number on the electronic bill, call 800-233-8931.
Retain copies of your EDI transmission acceptance reports as evidence of transmission.
If you have questions regarding electronic claims submissions, contact WorkCompEDI’s Services Representative at (800) 297-6909.
