The pupils nobody checked
Read enough notes and you start seeing the same reflexes. "PERRLA" on a patient whose pupils were never examined. A fourteen-point review of systems on a sprained ankle. A head-to-toe exam where most of the body was never touched. A generation of us learned to document this way, because for twenty-five years that padding was how you reached for a higher code.
Since 2021, that math no longer holds. The exam bullets do not raise your level anymore. So the padding buys you nothing on the coding side, and a line describing an exam you did not perform is a liability you did not need to take on. The new rules are, quietly, an invitation to write a shorter and more honest note.
- Since January 2021, history and exam no longer set the level of an office visit. Only medical decision making or total time does.
- That makes long, padded exams wasted effort, and any line describing an exam you did not perform is pure liability.
- A focused note that names the problems, the data, and the risk can code higher than a full-page one.
From 1995 until 2021, the level of an office visit was decided by counting things: elements of history, organ systems examined, bullet points in the exam. Those were the 1995 and 1997 documentation guidelines, and they governed E/M coding for about twenty-five years. They rewarded volume of documentation rather than complexity of thought, and they are the reason a generation of notes grew bloated with detail that did nothing for the patient.
Effective January 1, 2021, the AMA and CMS threw most of that out. For providers who learned documentation under the old rules, this change is genuinely good news. The new system respects your time and rewards your clinical thinking instead of your typing.
What actually changed
The 2021 revisions to office and outpatient E/M coding (99202 to 99215) made three fundamental changes.
History and physical exam no longer determine code level. You still document a medically appropriate history and examination for each patient. But those elements no longer drive code selection. A detailed, multi-system exam does not earn you a higher E/M code under the current rules. Only medical decision making (MDM) or total time determines the level.
Code selection is based on MDM or total time. You choose whichever supports the higher code and documents the encounter honestly. For most clinical visits, MDM is the better choice. For counseling-heavy or coordination-heavy visits, time often supports a higher level than MDM alone would.
99201 was eliminated. The lowest new-patient code is gone. New-patient codes now run 99202 to 99205. Established codes remain 99211 to 99215.
Time-based coding changed too
Under the old rules, time-based coding could only be used when counseling and coordination dominated the visit, meaning more than half the face-to-face time. That requirement is gone.
Under the current rules, total time on the date of service can select any office or outpatient E/M code, regardless of what that time involved. And total time now includes work done outside the room: reviewing records before the visit, answering staff questions, ordering and reviewing tests, and coordinating care, as long as it happens on the same calendar date.
| CPT | Patient status | Time (minutes) |
|---|---|---|
| 99202 | New patient | 15 to 29 |
| 99203 | New patient | 30 to 44 |
| 99204 | New patient | 45 to 59 |
| 99205 | New patient | 60 to 74 |
| 99212 | Established patient | 10 to 19 |
| 99213 | Established patient | 20 to 29 |
| 99214 | Established patient | 30 to 39 |
| 99215 | Established patient | 40 to 54 |
These are ranges, not minimums. A 99215 requires 40 to 54 minutes. You cannot code 99215 because you spent 40 minutes with a patient if 35 of those were spent waiting for an interpreter. Time must be your time spent on qualifying activities.
Why many of us still write the old way
It has been several years, and the reason many providers still use old habits is simple: nobody formally retrained them. The old habits are deeply ingrained, extensive review-of-systems templates and long exam checkboxes, and they feel protective because they always have. The problem is that they no longer serve their original purpose.
A note can be long and templated and still not support the code it is coded under, if the MDM elements are not clearly documented. A shorter note that explicitly addresses the number and complexity of problems, the data reviewed, and the risk of the decision can fully support a high-level visit.
"A longer, more detailed note is a safer note."
Since 2021, length does not raise your code, and any line describing an exam you did not perform raises your liability. A focused note that shows your decision making is both safer and higher-coding.
"I need a full review of systems and exam to support a level 4."
You do not. The level is set by MDM or time. A focused, medically appropriate exam plus a clear assessment and plan supports the same code with far less typing.
What the new system rewards
The 2021 system rewards clinical transparency. If you are managing a patient with three chronic conditions, one progressing and needing a new medication, that is a moderate-to-high complexity encounter. The new rules ask you to say that explicitly: name the problems, identify the data you reviewed, and articulate the risk in your decision.
Most providers already think through all of this. The documentation gap is not a clinical gap. It is a communication gap: the note needs to tell the story of the decision you made, not just list what you observed.
"A line documenting an exam you did not perform is a liability you did not need to take on."
Two notes, same patient, same visit
Picture one encounter documented two ways. The old-school note runs a full page: a fourteen-point review of systems, a head-to-toe exam, much of it irrelevant to why the patient came in. It looks thorough. But if the assessment and plan does not make the decision making visible, it can land at a level 3. The second note is half the length. It records the two chronic problems and their status, the labs and outside records reviewed, and the medication decision with its monitoring, then stops. It documents less but codes higher, a level 4, because it shows the complexity the coding system actually scores. The lesson is not to write less for its own sake. It is to write the things that carry the visit.
