I think this is a bug rather than a feature request, but we'll see what you think.
If a procedure with the "Do Not Bill Insurance" flag set is changed to something which by default should go to insurance - the box is not automatically unchecked. We've had several cases where a tooth went from a "watch" to a procedure with a fee, but the treatment plan shows the patient will have to pay for it because it was still set to not bill insurance from the original watch procedure. Can this be easily fixed?
If it starts as a procedure that would go to insurance and you change it to one that should't.... OD even makes an insurance estimate for the procedure that woud not normally get billed to insurance, or at least it did in May 2008.
