What is an impairment rating and what is MMI?
When a doctor determines that you have reached a point in the medical treatment where he or she can determine with some sense of assurance the type of medical care you may need in the future you have reached MMI. In other words, It means you are as good as you are going to get. You may not be as good as you were before the accident, but your condition is stable and you have a loss. This is when we request a final narrative statement of your condition. It is at that point that some doctors assign, and insurance companies generally request, a permanent impairment rating. This is generally done pursuant to American Medical Association guidelines. Automobile issuance companies often require the impairment rating to evaluate a case.
