When a provider orders a strep test and reports dx code R07.0 (pain in throat) and then the strep test comes back positive so the provider also assigns J31.2 (chronic pharyngitis) should the diagnosis R07.0 be removed from the visit note? I know these 2 codes cannot be billed together, however I was wondering if the R07.0 should remain on the visit note and J31.2 be reported on the claim by itself.
