This may be due to the fact that your attorney does not regularly use, when it is warranted, an AMA Impairment rating in his or her personal injury law practice.  It is important to understand that if an AMA Impairment is warranted in a person's California Personal Injury case, it is by far the most important "value driver" in the case apart from the individual injuries themselves.  If the case goes to trial, and the AMA impairment is missing, and it was warranted, how is the lawyer going to prove not only permanent impairment to a particular body part, or parts, but duties under duress, and loss of enjoyment of life damages, including future medical care?
