On my workflow, once a team member changes the status of an issue to Denied, I don't want them to be able to change it to anything else, essentially locking at that status so it is escalated to a different team to work it through the rest of the work flow.
These are the status's being used and the way that and issue can be moved through them:
To Do -> Processing
Processing -> Denied or Paid Or On Hold
Denied -> Appeal, Paid, Medical Records, Written Off
Paid -> To Do or On Hold
Appeal -> Paid or Written Off
Medical Records -> Paid or Written Off
On Hold -> To Do
Written Off
