You are right, Jon.
But I usually put in both ICD9 and ICD10 codes in the dropdown list, so when I do change over, most of the ICD9 codes will be converted by the software.
I probably will change over pretty soon, but I'm waiting for signals (Bert seems relatively positive now) that 8.1.* is mature. It will take me a weekend and who knows how much staff unhappiness the next Monday to make the switchover.
Just don't have the psychic energy for that right now.
