- 99211-99215 report office/outpatient E/M visits for established patients (seen within the past 3 years).
- Levels are selected by medical decision-making (MDM) or total time on the date of service — history and exam no longer drive the level since the 2021 E/M rules.
- 99211 requires no physician presence; 99212-99215 escalate from straightforward to high complexity.
- Accurate level selection plus clean documentation is the single biggest lever for reducing E/M downcoding and audit risk.
This guide explains how to select, document, and bill each level of the 99211-99215 family under the 2026 CPT and Medicare rules, including the time thresholds, MDM grid, common modifiers, and the denials that most often hit established-patient office visits.
What are CPT codes 99211-99215?
CPT codes 99211-99215 describe office or other outpatient evaluation and management (E/M) services for an established patient — a patient who has received professional services from the physician (or another physician of the same specialty and group) within the previous three years. The five codes form a ladder of increasing complexity and reimbursement, from a minimal nurse visit (99211) to a high-complexity physician encounter (99215).
Since January 1, 2021, level selection for these codes is based on either medical decision-making (MDM) or total time spent on the date of the encounter. The older 1995/1997 documentation rules requiring specific history and exam bullet counts no longer apply to office E/M.
99211-99215 at a glance: level, MDM, and time
Use the reference table below to match each code to its MDM level and time threshold. For time-based selection, count total practitioner time on the date of service, including non-face-to-face work such as chart review and documentation.
| CPT Code | MDM Level | Total Time (2026) | Typical Use |
|---|---|---|---|
| 99211 | N/A (minimal) | No time threshold | Nurse/MA visit; minor service, no physician required |
| 99212 | Straightforward | 10-19 minutes | Single minor self-limited problem |
| 99213 | Low | 20-29 minutes | Stable chronic illness or low-risk acute problem |
| 99214 | Moderate | 30-39 minutes | One+ chronic illness with exacerbation, or new problem with workup |
| 99215 | High | 40-54 minutes | Severe exacerbation or threat to life/bodily function |
How to select the right level: MDM vs. time
You may choose the level using whichever method — MDM or time — supports the higher, properly documented code. The two paths:
Path 1: Medical decision-making (MDM)
MDM is scored across three elements, and the level is set by the two of three that are met or exceeded:
- Number and complexity of problems addressed at the encounter.
- Amount and/or complexity of data reviewed and analyzed (labs, imaging, external records, independent interpretation).
- Risk of complications from the problem(s), diagnostic testing, or treatment (including prescription drug management).
Path 2: Total time on the date of service
Add all of the practitioner's time spent on that calendar date: reviewing the chart, performing the exam, ordering tests, counseling, documenting, and coordinating care. Match the total to the time bands in the table above. Time alone, when documented, can justify the level even without meeting the MDM grid.
99214 vs. 99213: the most contested boundary
Most established-patient visits land at 99213 (low MDM) or 99214 (moderate MDM). The jump to 99214 typically requires one of the following:
- One or more chronic illnesses with exacerbation, progression, or side effects of treatment.
- A new problem with uncertain prognosis or an acute illness with systemic symptoms.
- Prescription drug management — starting, stopping, or adjusting a prescription medication (a moderate-risk element on its own).
- Ordering and reviewing a moderate amount of data (e.g., labs plus an external note).
Routine prescription refills, a single stable chronic condition, or an over-the-counter recommendation generally support 99213, not 99214.
99211: the nurse-visit code and its rules
CPT 99211 is unique: it has no required physician presence and no key components or time threshold. It reports a brief, medically necessary service that does not require the physician's personal evaluation — for example, a blood-pressure recheck, a wound check by a nurse, or a medication-administration assessment. Documentation must still show medical necessity and the identity of the staff member who performed and supervised the service. Billing 99211 for purely clerical tasks (such as a prescription pickup) is a frequent compliance error.
Medicare reimbursement for 99211-99215 in 2026
Reimbursement scales with the level. The figures below are approximate national non-facility Medicare Physician Fee Schedule amounts and vary by locality and annual conversion-factor updates; always confirm against the current year's fee schedule and your payer contracts.
| CPT Code | Approx. National Non-Facility Allowable |
|---|---|
| 99211 | ~$24 |
| 99212 | ~$58 |
| 99213 | ~$94 |
| 99214 | ~$133 |
| 99215 | ~$187 |
Because 99214 reimburses roughly 40% more than 99213, accurate level selection across a full patient panel has a material revenue impact — while systematically over-coding to 99214 without support is a leading audit trigger.
Common modifiers with 99211-99215
| Modifier | When to use |
|---|---|
| 25 | Significant, separately identifiable E/M on the same day as a procedure or other service |
| 95 | Synchronous telehealth visit delivered via real-time audio-video |
| 24 | Unrelated E/M by the same provider during a post-operative global period |
| 57 | E/M that resulted in the decision to perform major surgery |
Common denials on established-patient E/M claims
- Level not supported by documentation — the note does not justify the MDM or time billed (leads to downcoding or recoupment).
- Modifier 25 denials — the separately identifiable E/M is bundled into the same-day procedure.
- New-vs-established mismatch — billing an established code when the patient meets new-patient criteria, or vice versa.
- Frequency/medical-necessity edits — payer flags too-frequent visits or a diagnosis that does not support the visit level.
- Incident-to errors on 99211 — supervision or staff-identity requirements not met.

Documentation best practices
- Document the assessment and plan for each problem addressed — this is the core of MDM scoring.
- Record prescription drug management explicitly when it supports moderate risk.
- If billing on time, state the total minutes and what they covered.
- Link each diagnosis to the work performed so medical necessity is self-evident.
- Audit a sample of your 99213/99214 distribution quarterly against specialty benchmarks.

Frequently asked questions
99213 reflects low medical decision-making (a stable chronic problem or low-risk acute issue), while 99214 reflects moderate MDM — such as a chronic illness with exacerbation, a new problem with workup, or prescription drug management. By time, 99213 is 20-29 minutes and 99214 is 30-39 minutes on the date of service.
Yes. 99211 is the only code in the family that does not require physician presence and has no time or key-component threshold. It reports a brief, medically necessary service performed by clinical staff, such as a nurse blood-pressure check, under appropriate physician supervision. Documentation must show medical necessity and who performed the service.
Either one. Since 2021, you select the level using whichever method — total time on the date of service or medical decision-making — supports the higher, properly documented code. History and exam no longer determine the level for office E/M.
Modifier 95 indicates a synchronous telehealth service delivered via real-time interactive audio-video. The appropriate E/M level (99212-99215) is still selected by MDM or time, with modifier 95 appended and the correct place-of-service code applied per payer rules.
The most common reason is that the documentation did not support moderate MDM — for example, no chronic exacerbation, no prescription drug management, and insufficient data review — or the time statement lacked supporting detail. Strengthening the assessment-and-plan documentation for each problem usually resolves it.
These five codes are for established patients only — those seen by the provider or a same-specialty group colleague within the previous three years. New-patient office visits use the 99202-99205 family instead.
