Thursday, September 04, 2014 ICD-10 Testing Dates Announced After several delays, the Centers for Medicare and Medicaid Services (CMS) is now ready to test its International Classification of Diseases, 10th Revision (ICD-10) system with providers before the October 1, 2015, startup date for use of the new codes. APTA is encouraging members to participate in the testing program to make sure that their own systems, billing companies, and clearinghouses are ready for the changeover. The testing program will be held over 3 separate weeklong sessions—one this November 17-21, and 2 in 2015, March 2-6 and June 1-5. Members only need to sign up for 1 session to find out whether their Medicare administrative contractor (MAC) will be able to accept claims with the new codes. The MACs will post information on how to participate in the tests. More information on the program can also be found in a Medicare Leaning Network bulletin (.pdf).
