S.C. Code § 15-3-530 South Carolina Code allows Three years. Apparently, South Carolina can claim or commandeer any State Income Tax refund you may have coming back and send it to hospitals, or doctors for unpaid bills -- EVEN if the bills are not owed because of a mixup or negligence on the part of the insurance company. There is no Due Process required via a judgment, no legal remedy, and no protection from this Draconian State practice. The worst and most criminal of these policies actually allows doctors to collect from spouses of deceased individuals even years after their spouse died. And, South Carolina will collect from your state income tax return for bills owed by your dead spouse in other states.
Although the above is somewhat true, it only applies the recovery of monies owed to Medicaid not to private medical caregivers.
