Concern With Submitting Bills After ICD-10 Transition Date

A member of PRN’s Coders Network Listserv has posted the following question:

I read the announcement Medicare released regarding “clarifying questions” and I was hoping you can help shed some light on a question that was posed to me. I understand that any DOS on or after 10/1/15 have to be billed using ICD-10, but what happens to DOS prior to 10/1 that haven’t been submitted? We are trying to encourage our providers to bill any outstanding billing as soon as they can, but we anticipate that not all will be able to do it.  So, what happens to billing w/ DOS prior to 10/1/15 that goes out after 10/1/15, will there be an issue processing it by the payor (specifically Medicare)?
