*Because there is no analyte code for Cryptosporidium or Giardia for “immunoassay with direct optical observation” (cartridges) – it is appropriate to use the analyte specific code for EIA for the two organisms (for cartridge formats). Since there is a specific code for Trichomonas “immunoassay with direct optical observation” – this number should be used. In the coding hierarchy, analyte comes before method. In the case of the rapid Plasmodium tests (dipsticks, cartridges), there is no analyte listed for EIA, so in these cases we need to use the nonspecific code: “Infectious agent antigen detection by immunoassay with direct optical observation, not otherwise specified” (87899).
NOTE: When using FA reagents or special stains for the coccidia or microsporidia, you should always perform these tests on centrifuged material, thus the need to add the concentration code 87015.
For multiple specimens/sites/patient/day use modifier ‘-91’
Example: blood for malaria (receipt of more than one specimen/patient/day). This is a repeat of the same test to increase analytical sensitivity
For repeat laboratory tests performed on the same day/patient, use modifier ‘-91’.
Example: multiple wet preparation exams for duodenal aspirate (examination of more than one wet preparation from a single specimen/patient/day).
For multiple stool specimens collected on different days, but submitted to the laboratory on one day: code for separate dates (no modifier required).
When considering a potential audit situation, remember that THE TEST CPT
CODES AND BILLS SHOULD MATCH THE SAME TESTS AND BILLS FOR
THE TESTS THE PHYSICIAN ORDERED. THEREFORE, IT IS CRITICAL
THAT YOUR REQUISITION FORMS AND/OR COMPUTER ORDER SCREENS MATCH WHAT YOU ARE ACTUALLY CODING AND BILLING. This is now an issue since Giardia and Cryptosporidium (FA, EIA) have now been broken out and should be coded and billed as separate tests.
