CMS has been carefully monitoring the transition and is pleased to report that claims are processing normally. Generally speaking, Medicare claims take several days to be processed and, once processed, Medicare must– by law – wait two weeks before issuing a payment. Based on the metrics comparing ICD9 and ICD10 there are lesser claims denied due to invalid coding with ICD10 when compared to ICD9. So far so god, though Noridian for California and Nevada were denying all claims for chiropractic initially they have corrected their error and have reprocessed all previously denied claims.
