CMS accepted 90% of test claims during its final ICD-10 acknowledgment testing week, and no Medicare Fee-For-Service (FFS) claims systems issues were identified, the federal Medicare agency announced July 2.
 
During the testing week, held June 1-5, 1,238 submitters participated, sending in more than 13,100 claims. About 5.8% of testers were home health agencies and 2.4% were hospices, the federal Medicare agency says.
 
Acknowledgement testing gives providers a chance to submit claims with ICD-10 codes to the Medicare FFS claims systems and receive confirmation that their claims were accepted.
 
“Most rejects were the result of provider submission errors in the testing environment that would not occur when actual claims are submitted for processing,” CMS says. Some errors, for instance, involved future dates of service.
 
Prior acknowledgment testing weeks were held in March 2014, November 2014 and March 2015. Although the latest acknowledgement testing week was the final one, agencies can submit acknowledgement test claims anytime until Oct. 1.
