Testing for Medicare Providers

For New Medicare Direct Submitters

Medicare testing process information is available at

After adding a direct Medicare 837 transaction in EDISS Connect, allow 10 business days for EDI Support Services (EDISS) to complete testing setup. When setup is complete, submit a Medicare 837 Test file and review the TA1, 999, and 277CA Acknowledgement Reports.

Once a provider has received a clean 277CA Acknowledgement Report, EDI Support Services (EDISS) will ensure the 837 transaction is approved in EDISS Connect. For help, please contact EDISS.
