In preparation for the October 1 ICD-10 implementation deadline, the Centers for Medicare & Medicaid Services (CMS) have completed their third Medicare fee-for-service end-to-end testing with great success, according to a recent CMS report. This is the third successful CMS ICD-10 testing to occur in 2015.
The testing week, which occurred between July 20 and 24, included healthcare providers, clearinghouses, and billing agencies. These entities utilized the help of Medicare Administrative Contractors (MACs) and the Durable Medical Equipment (DME) MAC Common Electronic Data Interchange (CEDI) to file their claims. Participants from previous tests were invited to partake in the July tests, thus bringing a considerable amount of returners to this session.
The July test was a success, according to CMS, with an 87 percent acceptance rate of the 29,286 claims received. The rejection rate for ICD-10 errors was 1.8 percent, and the rejection rate for ICD-9 errors was 2.6 percent. However, majority of rejected claims were not ICD-10 related. Among others, these included invalid NPIs, claims outside of the covered date range, and invalid place of service. CMS confirms that many of these same errors occurred in previous test sessions.
Additionally, CMS states that many rejected claims may have been submitted with errors on purpose. This practice, referred to as “negative testing,” is intended to ensure that CMS’ rejection processes are functioning properly and will indeed reject a provider’s invalid claim.
CMS reports a larger cross-section of volunteers this test session, with about 1,200 organizations selected to participate in the test. There were 493 organizations returning for previous tests. Additionally, 1,400 National Provider Identifiers (NPIs) participated in the test, and approximately 12 percent of those were repeats from prior tests.
This test brought about similar results to previous tests performed in January and April. In January, CMS reported an 81 percent approval rating between January 26 and February 3. This test included 661 volunteers. Just like this most recent test, the January test boasts a high success rate, with a majority of rejected claims resulting from non-ICD-10 related errors.
Tests performed in April were likewise successful. With 875 participants, CMS reported an 88 percent acceptance rate, which is consistent with the July tests. The number of rejections due to ICD-10 and ICD-9 errors are also consistent with the July tests, with a majority of rejections being due to other provider-related issues.
As providers and payers alike continue to prepare for the impending October 1 ICD-10 deadline, these test results bring promise to CMS. Not only have CMS’ systems shown a proven capability for accuracy, but they have shown consistent accuracy, with only a seven percent difference between the best and worst test performances. Provided these positive results, CMS has shown that it is ready for this new coding system.
