Wiki influenza A & B testing

[kattekatt]

Our office will be doing the influenza testing for A and B w/ CPT code 87804-- my question is that if we do the test for both A and B strains how do we code this? We will be using CPT code 87804-- BCBS states to use modifier 91, others have stated to use Modifer 59. if your opinion which is the correct way to code this ? Thanks in advance for any help

Flu Testing

What test kit are you using?

 

[RebeccaWoodward*]

We perform this test and have had great success with modifier 59.

[sfinke]

use modifier -59 on the second one. It's the proper one to use and is paid by most carriers

You have to specify the results for both test.

We've used -91

in the past without issue. However, it is up to what the individual carriers want.
