ICD-10 Acknowledgement Testing Week is Coming – November 17th – 21st, 2014
Acknowledgement Testing
Providers, suppliers, billing companies, and clearinghouses are welcome to submit acknowledgement test claims anytime up to the October 1, 2015, implementation date. In addition, the Centers for Medicare & Medicaid Services (CMS) will be highlighting this testing by offering three separate weeks of ICD-10 acknowledgement testing. These special acknowledgement testing weeks give submitters access to real-time help desk support and allows CMS to analyze testing data. Registration is not required for these virtual events.
All MACs and the DME MAC Common Electronic Data Interchange (CEDI) contractors will promote this ICD-10 acknowledgement testing with trading partners. This testing allows all providers, billing companies, and clearinghouses the opportunity to determine whether CMS will be able to accept their claims with ICD-10 codes. While test claims will not be adjudicated, the MACs will return an acknowledgment to the submitter (a 277A) that confirms whether the submitted test claims were accepted or rejected.
MACs and CEDI will be appropriately staffed to handle increased call volume on their Electronic Data Interchange (EDI) help desk numbers, especially during the hours of 9:00 a.m. to 4:00 p.m. local MAC time, during these testing weeks. The testing weeks will occur in November 2014, March 2015, and June 2015. Please watch for future CGS email messages and News articles related to the upcoming acknowledgement testing
