I installed AC 3.5.8 today on a test system, and all seems to be OK so far. I don't know for how long the CPT modifier column has been incorporated into the SIGN ENCOUNTER screen, but it's good to see that there is now a place for them. Also good to see that the G and Q codes are now "officially" recognized. Would be good to have AC 2's "No Charge" button when signing bills, so we can deal with ins. billing restrictions.
