E/M Coding 2026: MDM or Time, Whichever Pays Higher
The framework, still true in 2026
Since the AMA's 2021 overhaul — and confirmed unchanged by the CY 2026 Physician Fee Schedule — every office and outpatient visit (99202–99215) is chosen by either Medical Decision Making (MDM) or total time on the date of service. You evaluate both and bill whichever produces the higher level. That's the whole rule. History and exam are no longer scoring elements; they must be medically appropriate and documented for clinical and legal reasons, but counting HPI bullets and exam systems is stale guidance. Practices still coding that way are almost always under-coding their moderate-complexity visits.
One constraint: choose one method per encounter. You can't take the "problems" element from MDM and borrow time for the rest — it's MDM or time, start to finish. (99201 was deleted in 2021; the office/inpatient level-one consult codes 99241/99251 in 2023.)
Path 1 — Total time (2026 thresholds)
Total time is everything the billing provider personally does for that patient on the date of service: chart review, the visit itself, ordering tests and prescriptions, documentation, and care coordination. It excludes clinical-staff time and anything done the day before or after.
Audit-proof documentation names the number and the work: "Total time on date of service: 34 minutes, including chart review, encounter, ordering labs, and documentation." A bare "35 minutes" with no breakdown is what reviewers strip out.
Path 2 — Medical Decision Making (2 of 3)
MDM is scored on three elements. To reach a level, the visit must meet or exceed it in at least two of the three — so one element can lag if the other two carry it.
Abbreviated from the AMA MDM table (new-patient 99203–99205 mirror these levels). Prescription drug management alone lands the Risk element at moderate — one reason so many established follow-ups are legitimately 99214. Use the full CPT/AMA table for edge cases.
The 99214 benchmark — and payer downcoding
99214 is the workhorse most practices under-bill. For established visits, primary care generally lands 99214 on roughly a third to half of encounters, and complex specialties (cardiology, endocrinology, GI, pulmonology, neurology) higher still. Consistently billing mostly 99213 when the documentation supports 99214 is quiet, recurring revenue loss — and prescription drug management alone often justifies the moderate level via the Risk element.
The counter-pressure: many commercial payers now run automated downcoding programs on the higher levels (99204–99205, 99214–99215), lowering the billed level — sometimes without first reviewing the documentation — when their algorithm decides the diagnosis doesn't warrant it. The defense is specific, complete documentation and appeals; the AAFP and AMA actively contest opaque downcoding. Practically: know which of your payers downcode (it belongs in your payer policy tracking), watch your own level distribution so you're neither an outlier nor leaving money on the table, and when a same-day procedure is involved, get modifier 25 right so the E/M survives.
Two more codes worth money: G2211 and prolonged services
G2211 is a Medicare add-on to 99202–99215 that recognizes the ongoing work of being a patient's continuing focal point of care, or managing a single serious/complex condition over time. There's no frequency limit — it can be added at every qualifying visit — and since January 1, 2025, Medicare allows G2211 even when modifier 25 is on the same-day E/M for certain preventive services, which opened it up for a lot of primary-care visits that previously couldn't capture it.
Prolonged services pick up where the top code's time ends: commercial payers use +99417 for each additional 15 minutes beyond 99205/99215; Medicare uses G2212, which requires exceeding the maximum time of the highest level by more than 15 minutes. And a reminder that catches people: emergency department E/M is MDM-only — time cannot be used to set the level there.
What a visit actually pays in 2026
Payment for any service is its total RVUs × the conversion factor × the geographic adjustment (GPCI). For 2026 there are — for the first time — two conversion factors: $33.5675 for qualifying APM participants and $33.4009 for everyone else, both up from the 2025 factor of $32.35. A wrinkle worth knowing: the 2026 rule also applies a −2.5% "efficiency adjustment" to the work RVUs of most non-time-based codes (procedures, imaging, diagnostics), while time-based codes are spared — so procedure-heavy specialties feel downward pressure even though the conversion factor rose.
The takeaway for E/M: because office-visit codes are largely time-and-cognition based, they held up comparatively well in 2026 — which makes coding each visit at the level the documentation supports the most reliable revenue lever you control.

Is your E/M distribution leaving revenue on the table?
Under-coded 99214s and payer downcoding are the two biggest E/M leaks we find. A coding audit shows your level distribution against specialty benchmarks and what it's worth.
