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.
