Contact the agent or group who sold you the policy. My husband bought our policy thru his retiree union. After my accident, I called the union and they sent me the forms for my doctor to complete. I sent to the union office and they got it filed and payments started. My check is paid directly to my checking account each month.
In Virginia it is the SCC : State Corporation Commission
Great financial advice and lots of folks who are knowledgeable about insurance.
