Are you an attorney? You say you've handled thousands of claims but yet you refuse or cannot answer a simple question. So, here's another question for you, can a worker's comp carrier use a Nurse Practitioner to render a causation opinion? In the state of Tennessee, a nurse practitioner is NOT QUALIFIED TO MAKE A CAUSATION OPINION ! You say the mediator cannot "order" a settlement, this is partially true. When an injured worker has proved beyond a "preponderance of the law" that he has been denied medical treatment, he can and did state, and I quote, "if parties cannot reach an agreement to settle, I'll have no choice but to turn it over to the Workers Compensation Court "! End quote.
