Help please. I don't have a lab background and I'm confussed about the difference between 87804 & 87400. We have a test that checks for influenza, both A & B. How do I know which code to use??
While researching the codes this is what I found...
87400 enzyme immunoassay (EIA) technique.
>Blood specimen is serum
>Testing usually in acute phase & repeat again in 10-14 days
>If testing performed separately for Influenza A & B; report twice
87404 immunoassay with direct optical observation
>infection identified by direct detection of the virus in respiratory secretions (throat swab,nasal aspirate, nasopharyngeal swab or
sputum)
>specimen usually collected within 1 week of onset of symptoms
> method: EIA with monoclonal antibodies to detect viral antigen
> Again, may bill 2 units for separate results (A & B)
