WASHINGTON, D.C. (August 27, 2015)—From July 20 through 24, 2015, Medicare Fee-For-Service (FFS) health care providers, clearinghouses, and billing agencies participated in a third successful ICD-10 end-to-end testing week with all Medicare Administrative Contractors (MACs) and the Durable Medical Equipment (DME) MAC Common Electronic Data Interchange (CEDI) contractor. CMS was able to accommodate most volunteers, representing a broad cross-section of provider, claim, and submitter types.

This final end-to-end testing week demonstrated that CMS systems are ready to accept and process ICD-10 claims. Approximately 1,200 providers and billing companies participated, and testers submitted over 29,000 test claims. View the results here.

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. The acceptance rate for July was similar to the rates in January and April, but with an increase in the number of testers and test claims submitted. Most of the claim rejections that occurred were due to errors unrelated to ICD-9 or ICD-10.

Through its robust system release testing, CMS has ensured that the Medicare FFS claims processing systems changes for ICD-10 implementation have been thoroughly tested and validated. CMS also has conducted an unprecedented additional level of testing to help providers prepare for ICD-10. This was the final end-to-end testing week, but providers are encouraged to participate in acknowledgement testing, which can be completed at any time prior to the implementation date.

Be Prepared

Medicare claims with a date of service on or after October 1, 2015, will be rejected if they do not contain a valid ICD-10 code. The Medicare claims processing systems do not have the capability to accept ICD-9 codes for dates of service after September 30, 2015; or accept claims that contain both ICD-9 and ICD-10 codes.

CMS has created a number of ICD-10 tools and resources for providers. One tool is the "Road to 10," aimed specifically at smaller physician practices with primers for clinical documentation, clinical scenarios, and other specialty-specific resources to help with implementation.
