ICD-10 testing

ICD-10 Testing 

Health care providers, clearinghouses, and billing agencies participated in a third  ICD-10 end-to-end testing week with all Medicare Administrative Contractors (MACs).
  
Overall, participants in the July end-to-end testing week were able to successfully submit ICD-10 test claims and have them processed through Medicare billing systems.

In some cases, testers may have intentionally included errors in their claims to make sure that the claim would be rejected, a process often referred to as “negative testing.

  • 29,286 test claims received
  • 25,646 test claims accepted
  • 87 % acceptance rate
  • 1.8 % of test claims were rejected due to invalid submission of ICD-10 diagnosis or procedure code
  • 2.6 % of test claims were rejected due to invalid submission of ICD-9 diagnosis or procedure code
Additional rejections were from non-ICD-10 related errors 
  
No new ICD-10 related issues were identified in any of the Medicare fee-for-service claims processing systems.

There were zero rejects due to front-end CMS systems issues.
