I do not believe there is a way to tell when you converted from V5 to V6. Probably if you go into the tracking log.
You are using a certified version when you apply.
You have been using an EMR for > 90 days. Both are true statements. Just that you may not have been using a certified version for 90 days. Not sure how the wording goes. I started with V6 in April, but Medicaid IL is not ready to cert yet.
