The second ICD-10 end-to-end testing week produced promising results for healthcare providers, clearinghouses and billing agencies who voluntarily submitted claims using the new billing codes, producing higher acceptance rates than the previous testing week in January.
In the April testing week, the acceptance rate of test claims reached 88 percent, up from 81 percent accepted in January, according to CMS data.
Just 2 percent of test claims were rejected due to an invalid submission of an ICD-10 diagnosis or procedure code, and less than 1 percent of test claims were rejected due to an invalid submission of an ICD-9 diagnosis or procedure code. These rates of rejected claims were less than those in January, when 3 percent of claims were rejected for both invalid submission of ICD-10 and ICD-9 procedure or diagnosis codes.
ICD-10 is scheduled to go into effect Oct. 1, 2015. The CMS data brief indicates that any Medicare claims with a service data on or after Oct. 1, 2015 will be rejected if it does not contain a valid ICD-10 code.
