>Anyway, my only other IDC related story is that of going from ICD-9 to ICD-10, when decimals came into play. We had several projects where we had to go back and do global replaces on ICD-9 codes to play nicely with the ICD-10 codes. I like how ICD 9 and 10 don't use mutually disjoint sets of codes so there's a tiny overlap where the same code is present in both but means very different things. But only a tiny overlap so a QA cycle probably won't catch the issue.
