- Every CPT code carries a work RVU that your employer multiplies by a conversion factor. Coding a 99214 as a 99213 gives away 0.62 wRVU per visit, close to $145,000 a year at twenty visits a day.
- Accurate coding is not coding higher. Overcoding is improper, but systematic undercoding misrepresents the encounter too; the standard runs both ways.
- A procedure is not automatically worth more than a visit. A large-joint injection is 0.79 wRVU, a level 4 visit is 1.92, and modifier 25 is what lets you capture both.
- Since January 2021, only medical decision making or total time sets an office visit level. History and exam bullets no longer count, so a focused note that names the problems, data, and risk can code higher than a full-page one.
The $145,000 you already earned and did not get paid for
In fellowship, nearly every attending coded a level 3 for almost every visit, because it felt safe and took no thought. I did the same until a missed bonus made me look at the math. Overcoding gets flagged; undercoding just gets paid quietly.
Why Coding Matters
How a code becomes your paycheck
Every encounter is assigned a CPT code, and each code carries a set number of work relative value units (wRVUs). Your employer multiplies those wRVUs by a conversion factor, and in most contracts your wRVU total also decides whether you clear the thresholds that unlock bonus pay.
The code reflects what the documentation supports. If your note supports a level 4 established visit (99214) but is ambiguous enough that a cautious coder assigns 99213, you lost 0.62 wRVU.
| CPT | Established visit | wRVU | Difference from 99213 |
|---|---|---|---|
| 99213 | Low complexity | 1.30 | n/a |
| 99214 | Moderate complexity | 1.92 | +0.62 per visit |
| 99215 | High complexity | 2.80 | +1.50 per visit |
At 20 established visits a day, that is about 12 wRVU a day, roughly 62 a week, and close to 2,900 a year: about $145,000 at $50 per wRVU, for the same work.
Why "just code a 3" feels safe, and costs you
Nobody teaches coding in training. You are told to document appropriately, a phrase with a specific meaning nobody spells out, so you default to a level 3 that never triggers an audit the way a level 5 might. The uncounted cost: suppressed productivity metrics, a smaller bonus, and complex work made invisible. A note that says "discussed options, plan as above" records real work but gives a coder nothing to support a higher level; the fix is a few sentences on the problems addressed, the data reviewed, or the risk in the plan.
Accurate, not aggressive, not timid
The legal and professional standard is accurate coding. Overcoding, claiming more than the encounter supports, is improper, and in egregious cases it is fraud, with consequences up to repayment demands, Medicare exclusion, and criminal liability. But undercoding is not a safe harbor: recording less than you provided also misrepresents the encounter. The standard runs both ways.
The three objections, answered
"Isn't this the coders' job?"
Coders can only code what your note documents. They were not in the room, so an ambiguous note gets the cautious call, and you absorb the cost.
"I'm salaried, so RVUs don't matter for me."
Your wRVU production is tracked anyway and surfaces in your annual review, contract renewal, and bonus eligibility.
"I don't have time to learn this."
The core is a handful of concepts and a few extra sentences per note about things you already did. An evening to grasp, a couple of weeks to make automatic.
How You Get Paid: wRVUs, Conversion Factors, and the Fee Schedule
Physicians, NPs, and PAs are all paid through the same system. As a provider, you do not bill the insurer; you document and code, and your organization submits the claim. What you earn here means the credit your coding generates, as collections, wRVU productivity, or both.
The CPT code
A CPT code (Current Procedural Terminology, maintained by the American Medical Association) is the five-character label for a service, and each carries an assigned value. Values run from roughly 0.18 work RVUs (99211) to about 19 (27447), but most clinic work lives in a narrow band, which is why small, consistent coding differences add up.
The three parts of an RVU
Every CPT code in the Medicare Physician Fee Schedule carries a total RVU made of three parts.
| Component | What it represents | Approx. share |
|---|---|---|
| Work RVU (wRVU) | Your time, skill, effort, and clinical judgment | ~51% |
| Practice Expense RVU | Overhead: staff, equipment, supplies | ~45% |
| Malpractice RVU | Professional liability insurance costs | ~4% |
Your contract's wRVU productivity uses only the work RVU, the closest proxy for what you specifically did.
From RVUs to dollars
Medicare multiplies the total RVU (each component adjusted for local cost of living by a geographic index, the GPCI) by a national conversion factor, $33.40 for 2026.
Commercial payers negotiate separately, some as a percentage of Medicare, others on their own fee schedules. The wRVU is the same regardless of payer.
From wRVUs to your paycheck
As of early 2024, roughly 77 percent of US physicians were employed by hospitals, health systems, or other corporate entities. Your contract sets its own rate per wRVU, independent of the Medicare conversion factor. Typical employed models:
- Base salary plus bonus: a guaranteed base tied to a minimum wRVU expectation, with a bonus rate per wRVU above a threshold.
- Pure production: no guaranteed base; compensation is wRVUs multiplied by a dollar-per-wRVU rate.
- Tiered production: the per-wRVU rate rises as you hit higher productivity thresholds.
Employed rates typically run $40 to $80 per wRVU by specialty and market; orthopaedic surgery tends toward the high end, primary care toward the low. On straight salary or in private practice, the wRVU still measures your output for reviews and renegotiation.
wRVU values in practice
A 99214 is 1.92 wRVUs whether the payer is Medicare, Medicaid, or commercial; only the dollars per RVU change. Reference values:
| CPT | Description | wRVU |
|---|---|---|
| 99211 | Established patient, minimal (often nurse visit) | 0.18 |
| 99213 | Established patient, level 3 E/M | 1.30 |
| 99214 | Established patient, level 4 E/M | 1.92 |
| 99204 | New patient, level 4 E/M | 2.60 |
| 20610 | Aspiration or injection, large joint (e.g., knee) | 0.79 |
| 99291 | Critical care, first 30 to 74 minutes | 4.50 |
| 45378 | Colonoscopy, diagnostic | 3.18 |
| 47562 | Laparoscopic cholecystectomy | 10.21 |
| 27447 | Total knee arthroplasty | 19.11 |
| 27134 | Revision total hip replacement, both components | 29.52 |
Notice where the large-joint injection sits: 20610 is 0.79 wRVU, less than a level 3 visit at 1.30 and well under a level 4 at 1.92. Early on, the injection felt like the real medicine, and on days I did not separately code the visit I was giving away the larger of the two.
"A knee injection is worth 0.79 wRVU. The visit you did not separately code was worth more."
What you code is not what gets collected
Every claim goes through adjudication, where the payer applies its own rules, modifiers, bundling edits, and contract rates. Your productivity credit is typically based on the code as submitted, not on what was collected, so monitor your own wRVU reports.

The 2021 E/M Revolution: Why the Rules Changed and What It Means for You
"PERRLA" on a patient whose pupils were never examined. A fourteen-point review of systems on a sprained ankle. From 1995 until 2021, the 1995 and 1997 documentation guidelines set the visit level by counting history elements, organ systems, and exam bullets, so notes grew bloated with detail that did nothing for the patient.
Effective January 1, 2021, the AMA and CMS threw most of that out and asked a more honest question: how complex was the decision you made? Padding now buys nothing, and a line describing an exam you did not perform is a liability you did not need to take on.
What actually changed
The 2021 revisions to office and outpatient E/M coding (99202 to 99215) made three changes.
History and physical exam no longer determine code level. You still document a medically appropriate history and exam, but they do not earn a higher code.
Code selection is based on MDM or total time. Choose whichever supports the higher code honestly. For most visits that is MDM; for counseling-heavy or coordination-heavy visits, time often supports a higher level.
99201 was eliminated. New-patient codes now run 99202 to 99205. Established codes remain 99211 to 99215.
Time-based coding changed too
The old rules allowed time only when counseling and coordination took more than half the face-to-face time. Now total time on the date of service can select any office or outpatient E/M code, including same-day work outside the room: reviewing records, answering staff questions, ordering and reviewing tests, coordinating care. One example: an established visit that reaches 30 documented minutes is a 99214, and 40 minutes a 99215, whatever the MDM table would have said. The full time ranges for 99202 to 99215 are in Coding by Time, and the matching MDM levels and wRVUs are in the MDM guide.
The thresholds are ranges, not minimums, and the time must be yours on qualifying activities. You cannot code 99215 for a 40 minute visit if 35 of those minutes were spent waiting for an interpreter.
Why many of us still write the old way
Nobody retrained us, and long templates feel protective because they always have. But a long templated note can still fail to support its code if the MDM elements are missing, while a focused exam plus a clear assessment and plan supports the same code with far less typing.
What the new system rewards
The 2021 system rewards transparency. A patient with three chronic conditions, one progressing and needing a new medication, is a moderate-to-high complexity encounter, and the rules ask you to say so: name the problems, the data you reviewed, and the risk in your decision. The note must tell the story of the decision, not just list what you observed.
Two notes, same patient, same visit
One encounter, documented two ways. The old-school note runs a full page of review of systems and head-to-toe exam, much of it irrelevant to the visit; if the assessment and plan does not make the decision making visible, it lands at a level 3. The second note is half the length: the two chronic problems and their status, the labs and outside records reviewed, and the medication decision with its monitoring. It codes a level 4, because it shows the complexity the system scores. What to document for each level, column by column, is the subject of the guide on medical decision making.
