why are you billing for three test codes for influenza? It is possible you are using wrong modifer, wrong dx code, or both.
I tried it today let's see what they respond I wanted to knowIf you are doing the rapid influenza A and rapid influenza B code:
87804 and 87804-59. They are different tests with the same code. Perhaps Texas Medicaid (like Colorado) just doesn't like the modifier...you could try 87804 x2.
