The fee should automatically update when you change the procedure code for a treatment planned procedure.
Example: Let's say that the patient is scheduled to have #3 MO/R done, however, treatment changes to #3 MOD/R. The way it works now is you have to delete the #3 MO/R on the treatment plan and then re-treatment plan the #3 MOD/R and then add it to the appointment to set complete (or set complete from the patient chart). You have to do it this way because the fee will not update.
It would be great if you could just double click the treatment planned procedure (in the edit or delete procedure box), change the procedure code and the fee would automatically update.
