2 flu tests on one device? Use modifier 59

Why This Topic Matters

Influenza testing is common during seasonal surges, and coders need to know how authoritative guidance addresses reporting when one device produces multiple results. Understanding the article helps coding staff align documentation and claims with current CPT-oriented guidance.

   Describes the general issue raised by rapid tests that detect more than one influenza strain on a single device. Frames the coding question being addressed by the article.

3. AMA CPT Assistant guidance

   Summarizes the AMA response to the coding question and the general concept of reporting separate results when applicable. This section centers on CPT-oriented clarification rather than detailed rulemaking.

4. CPT manual microbiology guideline update

   Discusses related CPT microbiology guidance and the way the wording of the guideline was revised. Explains how the article connects that guidance to the broader coding topic.

5. Official resources
