The other driver's insurance company wants me to sign a medical authorization to get my records and bills related to injuries sustained in the crash. Should I sign it?
By signing the authorization, the insurance company also now has permission to talk directly to your treating physician. The insurance company may also ask your doctor to fill out a questionnaire in which he or she is asked when you will likely complete treatment. If your treatment takes longer than what the doctor estimated, the insurance company may claim that you are exaggerating your symptoms.
The better rule is not to sign the medical authorization until you have consulted with an attorney and discussed all of the ramifications.
