I am also noticing ICD-10 codes entered after October 1st have showed up "000" in subsequent encounters. Most annoying is hyperlipidemia E78.5, which always zeroes out. But many other common codes have the same behavior. I am now trying to use a different code "Endogenous hyperlipidemia E78.1" (whatever that is) which doesn't seem to zero out.
Whether intentional or not, the mapping from ICD-9 to ICD-10 has plenty of bugs, and so does the ICD-10 coding in AC 8.24.
