The Centers for Medicare and Medicaid Services on Thursday said its final testing round for end-to-end ICD-10 in July went off without a hitch, as healthcare providers, clearinghouses and billing agencies built on successes of earlier testing rounds.
With 1,200 providers and billing companies participating, testers submitting more than 29,000 claims. The acceptance rate for July was similar to the rates for weeks in January and April, but with an increase in the number of testers and test claims submitted, CMS said.
According to the agency, 29,286 test claims were received and 25,646 test claims were accepted, marking an 87 percent acceptance rate. CMS also said 1.8 percent of test claims were rejected due to invalid submission of ICD-10 diagnosis or procedure code and 2.6 percent of test claims were rejected due to invalid submission of ICD-9 diagnosis or procedure code.
In some cases, testers may have intentionally included errors in their claims to make sure that the claim would be rejected, a process often called negative testing. Additional rejections were from non-ICD-10 related errors, such as incorrect NPI, Health Insurance Claim Number, or Submitter ID; dates of service outside the range valid for testing; invalid HCPCS codes and invalid place of service.
No new ICD-10 related issues were identified in any of the Medicare fee-for-service claims processing systems, according to CMS. There were zero rejects due to front-end CMS systems issues and issues identified during previous testing weeks were resolved before July testing.
