ICD-10: CMS End-To-End Testing a Big Success

CMS released the results of its January 26-February 2 end-to-end testing week on a National Provider Call on Feb. 26th, and they were very positive.
The testing included healthcare providers, clearinghouses, and billing agencies from each Medicare Administrative Contractor (MAC). This test allowed submitters to send sample claims with ICD-10 codes to ensure that CMS could process them through their billing system. Almost 15,000 claims were received and 81 percent of those claims were accepted. Of the 19 percent that were rejected, only 3 percent were due to invalid submission of ICD-10 diagnosis or procedure codes. Approximately 3 percent were due to ICD-9 diagnosis or procedure code errors, and 13 percent were due to non-ICD-10 related errors, such as incorrect NPI numbers, Health Insurance Claim Numbers, Submitter IDs, invalid place of service, invalid HCPCS code, and dates out of range (valid for testing).
There was one issue identified with institutional claims for Home Health related to system edits. It affected fewer than 10 claims, and CMS has stated it will resolve the issue before the next testing. CMS also stated that it will offer tester education before the next testing week to avoid the non-ICD-10 related errors.
CMS will hold two more end-to-end testing weeks: April 27-May 1, 2015 and July 20-24, 2015. Registration for the April testing is closed, but registration will open for the final end-to-end testing week March 13-April 17, 2015 through the MAC and Common Electronic Data Interchange (EDI) websites.
A copy of the slide presentation and testing results from the National Provider Call are available on the CMS website, and the transcript from the National Provider Call will be available approximately March 12th.
