That's the code for what was performed so using "another" code would be misrepresentation of service
Per Blue Cross website:
The evidence for the use of a nucleic acid-based gastrointestinal pathogen panel in individualswho have signs and/or symptoms of gastroenteritis includes prospective and retrospectiveevaluations of the tests’ sensitivity and specificity. Relevant outcomes include test accuracy andvalidity, other test performance measures, symptoms, and change in disease status. The evidencesuggests that gastrointestinal pathogen panels are likely to identify both bacterial and viralpathogens with high sensitivity, compared with standard methods. Access to a rapid method foretiologic diagnosis of gastrointestinal infections may lead to more effective early treatment andinfection-control measures. However, in most instances, when a specific pathogen is suspected,individual tests could be ordered. There may be a subset of patients with an unusual presentationwho would warrant testing for a panel of pathogens at once, but that subset has not been welldefined. The evidence is insufficient to determine the effects of the technology on healthoutcomes.
