Workmans Compensation EMR.

Experience Modification Rates (EMR) are important to your business unless you don’t mind paying 25%-50% more for your insurance than you need to. A score of 1.0 means you pay the actual premium amount. The score runs from .75 to 1.25 which means up to a 25% discount or 25% increase. In short, it’s calculated by comparing the claim cost, to the payroll amount, factored by the classification code. The classification code is set by the National Council on Compensation Insurance (NCCI) in 39 states. 
Claims remain on the record for 3 years from the occurrence.  The EMR formula factors the actual claim cost and the expected claim cost. When a claim is initiated, the Adjuster must set a reserve, which is an estimated amount of money to cover the cost of the claim.  This is an important step for the insurance company; however, excessive reserves can unnecessarily affect the EMR. (You pay more for insurance.)   
The most important, and obvious step, in controlling the EMR will be to work safely and avoid injuries. However, there are other ways a company can influence this score in its favor. These include return-to-work programs, monitoring claim costs, monitoring reserves, and having a close relationship with the WC carrier. When a claim happens don’t just hand it over and walk away. If you are working to reduce claims and costs both before and after the injury, and the insurance carrier knows it, everyone is better off.   Having an agent who is willing and able to help is very helpful, don’t overlook them as they are a valuable resource. 
This is my opinion, based on lessons I have learned and some successes I have experienced. It is not legal advice, as I am not a lawyer, nor am I an insurance professional. I had to learn the hard way and figure it out. In the next few weeks, I will share more details and opinions.
