Medical Disclosure verification of debt Not disclosed as an attempt to collect South Carolina

I have an outstanding medical bill I was completely unaware of. I relocated cities and never received this bill or else I would have paid it immediately. I ran my credit on - - yesterday and was shocked to see I had an outstanding debt. Please let me know how I can resolve this issue ASAP!
