There are legal arguments to be made as to how having to reimburse your insurance is inequitable under the factual scenario that you have described. You are strongly urged to consult with a lawyer who can review the facts and make those arguments on your behalf.
It depends upon whether your health insurance has a reimbursement provision. If so, then one is generally required to reimburse. Often times a carrier will negotiate a lien reduction. If you had more than $8,000.00 in medical bills for injuries sustained in the incident, you really should have been represented by a personal injury attorney.
You probably should consult an attorney about your situtation.

Excess medical is secondary to your health insurance. It will pay for what is not covered or paid by your health insurance. If you can show that your medical bills were higher than the settlement, your insurance carrier will generally waive their excess medical payment.
