CMS Announces Results of Week of ICD-10 Acknowledgement Testing

The Centers for Medicare and Medicaid Services (CMS) announced that its week of ICD-10 acknowledgement testing this past March was a success. During this test week, testers submitted more than 127,000 claims with ICD-10 codes to the Medicare fee-for-service (FFS) claims systems and received electronic acknowledgements confirming that their claims were accepted.

“Nationally, CMS accepted 89 percent of the test claims, with some regions reporting acceptance rates as high as 99 percent. The normal FFS Medicare claims acceptance rates average 95 to 98 percent,” wrote Niall Brennan, acting director, CMS offices of enterprise management, in a blog post announcing the results on Friday, May 30. He added that the testing process did not reveal any problems with the Medicare FFS claims system.

According to Brennan’s post, about 2,600 participating providers, suppliers, billing companies, and clearinghouses participated, as well as providers including large and small physician practices, small and large hospitals, labs, ambulatory surgical centers, dialysis facilities, home health providers, and ambulance providers.

The testing week also allowed testers to conduct negative testing—a process in which testers knowingly insert errors in the claim to make sure the system rejects the claim as it’s supposed to.

Brennan noted that details about end-to-end testing, which has been delayed until 2015, will be announced soon.
