In order to change codes, a re-evaluation meeting must take place in which the team discusses whether they suspect an additional disability and/or new information has been presented. However, I believe that in most school systems mood disorders fit into the ED classification rather than the OHI classification. I do know, however, that there are many reasons to believe it could/should fall into OHI, but rarely does. You child should really be able to recieve any/all accommodations based on his/her needs being eligible for special education. The code does not drive the services available. Good luck
