In certain cases, if an ICD10 code does not have a well-defined treatment plan, OneChoice will select the most closely related infection, in an effort to provide guidance on the appropriate treatment. For example, an ICD10 code that specifies "chronic bronchitis", "chronic rhinitis", or "chronic sinusitis", which usually does not require antibiotic treatment will sometimes result in a OneChoice report that will state "treatment may not be indicated". In other cases, OneChoice will select the closest related diagnosis. For example, with a diagnosis code of "chronic UTI", OneChoice may select a treatment plan for "acute UTI" since treatment for chronic UTI is not well defined.
