If our practice tests in the office a rapid flu test for both A & B, can we bill 87804 twice for the same test and if not, how should it be billed?

When your office uses an A & B influenza test, you should code multiple units of 87804 when appropriate. Bill 87804 twice. Use modifier 59, distinct procedural service with the second unit of code 87804.

What about a modifier 91?

In this case you would want to use modifier 59 to show that the tests are distinctly different (A and B). Modifier 91 would indicate repeating the same test twice (twice for A or twice for B).
