aLevel is based on 2 out of 3 elements of medical decision making.
Abbreviations: E/M, evaluation and management; MDM, medical decision making; OTC, over the counter.

Number and Complexity of Problems Addressed

Patient complaints are cough, fever, dyspnea on exertion, nausea, and body aches.  This would fall under “1 acute illness with systemic symptoms,” which is Level 4.

Amount and/or Complexity of Data to Be Reviewed and Analyzed

In this case, the provider ordered a POCT influenza test and a COVID test. A chest x-ray was ordered and interpreted, but do not include this in your consideration if your company bills for the professional or technical component of the radiograph. This encounter would qualify as meeting the criteria for Category 1 in the Moderate section (ordering of each unique test x 2), which is Level 3.

Risk of Complications and/or Morbidity or Mortality of Patient Management

Tamiflu and Zofran were prescribed. Prescription drug management would meet the criteria for Level 4.

2 of the 3 Elements of Medical Decision Making must be met when choosing your level of service. This encounter met Level 4 criteria in 2 of the categories (Problems Addressed and Risk), so the correct E/M code is 99204.
