Chest Pain in a Chronic COPD Patient: MDM or Time?
Elena, a 68-year-old established patient, is seen in the office for three days of worsening cough, low-grade fever, and intermittent chest tightness. She has COPD, hypertension, and type 2 diabetes. On examination, she is wheezing and her blood pressure is 148/86 mmHg; a fingerstick glucose is 180 mg/dL. The physician orders a chest X-ray, CBC, BMP, and a 12-lead ECG performed in the office. The physician reviews prior pulmonary function tests, prescribes levofloxacin and prednisone, and adjusts her insulin. The note documents: 'Total time spent on the date of encounter: 35 minutes, including 12 minutes counseling about pneumonia precautions.' The ECG is billed separately with CPT 93000. The physician did not use a checklist but documented a full problem-oriented note. The coder must decide between 99214 and 99215 and must not count time for the separately reported ECG.
1. Select the correct E/M level using the 2021 office/outpatient MDM guidelines. Explain the three MDM elements and state why 99214 or 99215 is supported.

99214 is supported by moderate MDM. Problems: one acute illness with systemic symptoms (cough, fever, chest tightness) plus two stable chronic illnesses (COPD, hypertension, diabetes) - this is moderate complexity. Data: the physician orders four unique tests (chest X-ray, CBC, BMP, ECG) and reviews prior pulmonary function tests; this is at least moderate data. Risk: prescription drug management (levofloxacin, prednisone, insulin adjustment) is moderate risk. Two of the three elements are moderate, so 99214. 99215 would require high MDM: e.g., a chronic illness with severe exacerbation, an acute threat to life or bodily function, or high-risk decision-making such as admission. The note does not support that. The total time of 35 minutes also falls in the 99214 range (30–39 minutes) for an established patient, but the coder should use one method, not both. If using time, document total time and exclude time for separately reported services.
2. The physician submits a corrected note documenting 50 minutes total, including 30 minutes counseling. Can the practice bill 99215 based on time? What conditions apply?
Read the worked answer
Yes, if the 50 minutes is total time on the date of the encounter and the time is documented, 99215 is supported by time for an established patient (40–54 minutes). Under the 2021 guidelines, counseling no longer has to dominate; total time includes all activities, but it must not include time for separately reported services. The ECG is billed separately as 93000; the time spent performing or interpreting the ECG must be excluded. If the 50 minutes includes 10 minutes for the ECG, the E/M time is 40 minutes, still 99215. If it includes 15 minutes, the E/M time is 35 minutes, which supports 99214. The practice must choose either MDM or time; it cannot combine them. The note should state the total time and that the time was spent on the date of the encounter.
