Your note doesn't bill on its own. As a resident, you don't charge for the visit; your attending does, and their bill is built on the documentation you write. So the thinking you record, or leave out, moves someone else's code. Yet no one ever taught you how it works. Here's the five-minute version.
The rules were rewritten in 2021 for clinic visits, and in 2023 for hospital, ED, and other visit codes. History and physical exam no longer set the billing level. You don't need a 14-point review of systems and a full head-to-toe to justify a code. The note only has to be medically appropriate. Note bloat earns nothing now.
What sets the level is your medical decision-making. There are two paths in theory: decision-making or total time. But time counts the attending's minutes, not yours, so the lever you actually control is the thinking you document. (The ED is the exception either way: no time option there, decision-making only.) It comes down to three parts:
- Problems: how many you addressed, and how sick (a stable chronic condition versus an acute problem that threatens life or limb).
- Data: labs and imaging reviewed, outside records read, conversations with other clinicians.
- Risk: of the condition and of your management. "Started anticoagulation, weighed the bleeding risk, discussed with cardiology" is risk, written down.
The level is set by the higher two of those three, not all three.
The catch: the complexity has to be real, not invented. You are recording the work you did, not inflating it.
It cuts both ways. Under-document the decision-making and the visit is coded as less than it was. Over-document to feel safe and you lose your evenings for nothing. The move is to write the thinking down: the problems you addressed, the data you weighed, the risk you managed. That is what the code is built on now, and it is exactly the part residents leave out.
You'll never see the invoice. But you write its first draft every single day.
