Please help.

1. I work at a clinic that has a moderate complexity CLIA approved in house lab. I am a bit confused by the QW modifier. Do we still need to use the QW on Flu and strep swabs and urinalysis?

2. How are you getting paid for the 87804 (flu swab A and B)? I have always billed 87804-91 and 87804 and it paid. I am getting rejections on the modifier. Should I use 76, 59 or 87804 x2? Possibly XU? I am at a loss.
Thank you for your time.
