Annual Wellness Visit Plus New Chest Pain: Billing Two E/M Services
A 68-year-old established patient schedules a Medicare annual wellness visit (AWV). At check-in she mentions new exertional chest tightness that began two weeks ago and radiates to the left jaw. The physician completes the AWV elements, then takes a problem-focused history, performs a cardiac exam, orders an ECG and an outpatient stress test, starts low-dose aspirin, and documents moderate medical decision making. Total time on the date is 45 minutes, including 20 minutes of AWV counseling. The note lists 'AWV completed' and 'new onset chest pain, rule out angina.' The coder wants to report G0439 and 99214-25. The practice's compliance officer asks whether the claim will survive audit and whether time or MDM should drive the E/M level. The patient is not new, and the physician is the sole provider of both services.
1. Can the practice report G0439 and 99214-25 on the same claim? Explain the requirements.

Yes, both may be reported, but the problem-oriented E/M must be significant and separately identifiable from the AWV. Medicare allows the AWV and a same-day E/M when the E/M is above and beyond the preventive service. Modifier 25 communicates that the E/M is distinct; it does not create the distinction. The note must show a problem-focused history, exam, and medical decision making for the chest pain that are separate from the AWV elements.
The coder should not count the AWV history, exam, or counseling toward the problem E/M. The chest pain workup here includes a focused history, cardiac exam, ECG, stress test order, aspirin initiation, and moderate MDM, which supports a separate E/M. The AWV code remains G0439 for the established Medicare patient.
2. How should the coder choose between time and MDM, and what are the pitfalls?
Read the worked answer
For office E/M, the coder may select the level by either total time on the date of the encounter or medical decision making, but not by combining them. The 45 minutes cannot be used in full because 20 minutes belong to the AWV; counting that time twice would be double billing. If the coder uses time for the problem E/M, only the time attributable to the problem service should count. On these facts, the remaining 25 minutes would support 99213 by time, but the documented moderate MDM independently supports 99214. The coder should choose the basis that is best supported and document the choice.
The pitfall is reporting 99215 simply because the total visit was 45 minutes. Another pitfall is using the AWV time to reach a higher problem E/M level. Both are audit risks.
3. What documentation would cause the separate E/M to fail audit?
Read the worked answer
The separate E/M would fail if the note shows only a brief mention of chest pain with no separate history, exam, or MDM beyond the AWV. It would also fail if the chest pain work were routine preventive counseling, if the ECG were ordered as part of a screening rather than a problem evaluation, or if the problem E/M elements were actually the same elements used to complete the AWV. A vague statement such as 'chest pain discussed' without findings or decision making is not enough.
The compliance officer should look for a distinct problem-focused assessment and plan, the rationale for the ECG and stress test, and the medication decision. If those are absent, the practice should bill only the AWV or bill a problem E/M alone, not both.
