Hello, If a person receives a work comp lump sum settlement and 2 years later is seen for an issue related to the work comp injury, Medicare denied the claim as Workers Comp case settled. Patient is responsible. (This is our first Knowledge it was a work comp related case), the patient also has Medicaid. Can we or should we bill Medicaid (even for denial) or should we bill to patient? I say patient is responsible...my supervisor disagrees and said to find something in writing. This is in Ohio. What are the rules on this and where might I find something in writing? Thanks in advance.
