CPT code 87804
What does CPT code 87804 mean on a medical bill?
This is the quick nasal swab for influenza, read on the spot rather than sent to a lab. Each strain tested for is billed as its own line, so checking for both influenza A and influenza B often shows up as two lines from a single swab. That pairing is normal. What is worth asking about is a bill listing more respiratory tests than your record says were run from the sample you gave.
What should I watch out for with CPT code 87804?
- More test lines than results in your record from one swab
- Both the rapid flu test and a lab-run flu test billed from the same swab
- A respiratory panel billed on top of the individual rapid tests it already covers
