I have been migrating insurances by patient as they come up on the schedule, or if they call in for a medication refill, etc. We only see 20-25 patients per week in the office, so it's not a huge job. I figured this would be the easiest way to do it. We use a third party billing service that is not connected to AC, so I'm not too concerned about getting it done quickly. I'm also not worried about fixing our previous hospital patients, just adding the new ones correctly. I am making a list of those insurances that I cannot find on the codified list so I can pass them on to AC support.
