A patient needs to have a specific clotting factor tested for von Willebrand disease. He needs factor VIII, multimetric analysis testing performed. What is the correct CPT code for this laboratory test?
Explanation
Answer: D - 85247 is the correct code for factor VIII, von Willebrand factor, multimetric analysis.
Code 85210 is incorrect because this code is for clotting factor II, prothrombin specific. Code 85245 is incorrect because this is for factor VIII, von Willebrand factor ristocetin cofactor and 85246 is incorrect because this is specific for factor VIII, von Willebrand factor antigen. It is important to know the specific test ordered. In this case the physician had ordered the multimetric analysis of factor VIII von Willebrand factor.
