⚡  QUICK ANSWER: What Are CPT Codes 99211–99215?

They are the AMA CPT codes for Evaluation & Management (E/M) services at established patient office or outpatient visits — the most frequently billed physician services in U.S. healthcare.

Under current AMA guidelines (in effect through 2026), code selection is based on either Medical Decision Making (MDM) complexity OR total time on the date of the encounter — not history and physical examination elements.

99211 is the lowest level (typically nurse/MA visit with no MDM required). 99215 is the highest (high-complexity MDM or 40–54 minutes total time).

Documentation must support the code selected. Selecting a code level that the documentation doesn’t support is the most common compliance risk in E/M billing — whether the error is upcoding or downcoding.

Office visit codes 99211 through 99215 are the most billed CPT codes in the country and among the most audited. Every year, CMS and commercial payers direct significant audit resources toward E/M coding, and for good reason: even small, systematic errors in code selection across a busy practice compound into substantial overpayments or underpayments over time.

The 2021 AMA and CMS E/M guideline changes fundamentally restructured how these codes are selected, removing history and physical examination as drivers and replacing them with MDM complexity or total encounter time. By 2026, these rules are fully embedded in standard billing practice yet our team continues to audit practices whose documentation workflows still reflect the pre-2021 approach, generating both compliance exposure and significant uncaptured revenue.

This guide gives every physician, coder, biller, and practice administrator a current, practical reference for CPT 99211–99215 in 2026 covering the code definitions, the MDM table, time-based billing, documentation requirements, the billing workflow, common mistakes, and what drives denials and audit risk across this critical code set.

📌 EEAT Compliance Note

This guide reflects AMA/CMS E/M documentation guidelines as updated in 2021 and in effect through 2026. Code descriptions, MDM criteria, and time benchmarks are based on the official AMA CPT manual and CMS E/M guidance. Payer-specific requirements may vary from the general guidelines described here. Always verify against your MAC’s published guidance and your specific payer contracts before submitting claims. See the Disclaimer at the end of this guide.

01 — What Are CPT Codes 99211–99215?

CPT 99211 through 99215 are the AMA’s designated procedure codes for outpatient or office-based Evaluation & Management services performed with established patients. An established patient is one who has received any professional service from a physician or qualified healthcare professional in the same specialty and subspecialty in the same group practice within the past three years or who has been seen before by the same provider.

These codes cover the physician’s cognitive work: evaluating a patient’s condition, reviewing their history and data, making clinical decisions, and managing their care plan. Under the AMA’s 2021 guidelines, which CMS adopted and which remain in effect through 2026, the code level is determined by: (1) the complexity of Medical Decision Making (MDM) a structured assessment of problems, data, and risk; or (2) the total time spent by the billing clinician on the date of the encounter, including pre-visit preparation, face-to-face time, and post-visit work such as ordering, documenting, and care coordination.

What no longer determines the code level: the number of history elements or examination systems reviewed. These may still be documented for clinical purposes, but they cannot be used to justify a higher billing level on their own under current guidelines.

02 — Quick Overview: All Five Codes

03 — Each Code Explained

CPT 99211 — Minimal Complexity Office Visit

CPT 99211 — Key Facts

Level: Minimal (no MDM documentation required). Physician presence: NOT required for this code.

Typical services: Blood pressure check, weight monitoring, injection administration, test results review by nursing staff, simple wound care, or medication refill by a nurse or medical assistant.

Incident-to billing (Medicare): If billed under the supervising physician’s NPI for Medicare, the supervising physician must be present in the office suite during the service. This rule is frequently misunderstood and represents a significant compliance risk.

Documentation: The visit must be documented, but there is no requirement to document MDM. The note must describe what service was provided and by whom.

Common mistake: Billing 99211 under the physician’s NPI when the physician was not in the office during the service an incident-to compliance violation.

CPT 99212 — Straightforward MDM Office Visit

CPT 99212 — Key Facts

MDM Level: Straightforward. MDM elements: One self-limited or minor problem. Minimal data reviewed. Minimal risk of complications.

Typical use: A patient presenting with a single minor acute issue (e.g., mild URI, minor skin lesion follow-up, routine medication review with no complications).

Time: 10–19 minutes of total encounter time may alternatively support this code level.

Documentation: Must document the problem(s) addressed. If using MDM, all three MDM elements (problems, data, risk) should be reflected in the note even when they’re minimal. If using time, document total minutes.

Common mistake: Using 99212 when the patient has two or more problems addressed or when time actually exceeded 19 minutes downcoding that leaves revenue uncaptured.

CPT 99213 — Low Complexity MDM Office Visit

CPT 99213 — Key Facts

MDM Level: Low complexity. MDM elements: Two or more self-limited problems, one stable chronic illness, OR one acute uncomplicated illness or injury.

Typical use: Follow-up for a stable hypertension patient, management of well-controlled diabetes, or a straightforward acute illness like sinusitis or urinary tract infection.

Time: 20–29 minutes of total encounter time may alternatively support this code level.

Documentation: The note must clearly reflect the problem(s) addressed. For MDM, at least low-level data elements (e.g., reviewing prior results, independent interpretation) and low risk (e.g., OTC medications, minor procedure) should be documented.

Common mistake: Billing 99213 by default for all chronic disease follow-ups without considering whether the encounter actually involves an exacerbation or additional problems that would support 99214.

CPT 99214 — Moderate Complexity MDM Office Visit

CPT 99214 — Key Facts

MDM Level: Moderate complexity. MDM elements: One or more chronic illnesses with exacerbation/progression/side effects, two or more stable chronic illnesses, one undiagnosed new problem with uncertain prognosis, or one acute illness with systemic symptoms.

Typical use: A diabetic patient with worsening glycemic control, a patient with hypertension AND hyperlipidemia at a routine visit, or a new symptom complex under evaluation.

Time: 30–39 minutes of total encounter time may alternatively support this code level.

Risk: At least moderate risk — prescription drug management, minor procedure with risk factors, or diagnosis/treatment requiring intensive monitoring.

Common mistake: Billing 99214 based on the diagnosis code alone (e.g., listing two chronic conditions) without documenting that the physician actively managed both problems during this encounter.

CPT 99215 — High Complexity MDM Office Visit

CPT 99215 — Key Facts

MDM Level: High complexity. MDM elements: One or more chronic illnesses with severe exacerbation, one or more acute or chronic illnesses or injuries posing a threat to life or bodily function.

Typical use: A heart failure patient presenting with decompensation; an ESRD patient with a serious complication requiring urgent management; complex psychiatric crisis or neurological deterioration.

Time: 40–54 minutes of total encounter time may alternatively support this code level.

Risk: High risk drug therapy requiring intensive monitoring for toxicity, emergency hospitalization decision, major surgery consideration.

Common mistake: Using 99215 for any complicated patient without ensuring the documentation reflects high-complexity MDM across all three elements: the problem, the data reviewed, AND the risk. Two out of three elements being high doesn’t meet the 99215 threshold under current guidelines.

04 — Documentation Requirements for E/M Office Visits

Under current AMA/CMS guidelines in effect through 2026, documentation for 99212–99215 must support the code’s basis either the MDM complexity level or the total time on the date of encounter. Here’s what must be in the record.

Documentation Element	What It Must Contain	If Missing or Vague
✔  Problem(s) addressed	A clear description of each diagnosis or condition managed during this encounter this drives the ‘Problems’ element of MDM	MDM level cannot be established; code selection unsupported on audit
✔  Data reviewed and ordered	Documentation of any external records reviewed, independent interpretations performed, or discussions with other providers — contributes to the ‘Data’ MDM element	MDM level may be lower than code reported; downcoding on audit
✔  Risk of management	Documentation of the clinical risk of the management decisions made — e.g., prescription drug initiated, procedure ordered, hospital referral considered	Risk element of MDM incomplete; high-complexity codes unsupported without documented high-risk management
✔  Total time (if time-based)	The specific total minutes spent by the billing clinician on the date of encounter, including all pre-visit, face-to-face, and post-visit work	Time-based coding invalid without specific minute documentation; default to MDM or deny
✔  Diagnosis-problem linkage	The specific problem addressed must connect to the ICD-10 code(s) on the claim	Diagnosis-code mismatch denial; medical necessity questioned
✔  Clinical assessment	Physician’s assessment of the patient’s condition relevant to the problems being managed	Insufficient documentation to support physician work value
✔  Plan of care	Orders placed, treatments initiated, referrals made, follow-up scheduled	Incomplete encounter documentation; audit exposure for higher-level codes
✔  Medication management (if applicable)	Any prescriptions started, changed, or discontinued with documented rationale	Prescription drug management is a high-risk MDM element; must be documented to support risk level
✔  Data from external sources (if applicable)	Results reviewed from outside labs, imaging, or specialty consultants; must name the source and the review action taken	Independent interpretation credit requires specific documentation, not a general reference
✔  Encounter date and provider identity	Date of service and identity of the billing provider clearly documented	Claim processing error; potential incident-to compliance issue

💡 2026 Documentation Tip: MDM Requires All Three Elements

Under current guidelines, MDM level is determined by meeting 2 of the 3 MDM elements (Problems, Data, Risk) at a given level. However, ‘meeting’ an element means actually documenting evidence of it — not simply implying it. If you’re billing 99214, the documentation must reflect moderate complexity in at least two of the three columns. A note that only describes the problem without referencing data reviewed or the risk of management decisions will not support a 99214 on audit.

05 — Medical Decision Making (MDM) Guide

MDM is the primary basis for E/M code selection for most office visit encounters. It is evaluated across three elements: the Number and Complexity of Problems, the Amount and Complexity of Data, and the Risk of Complications. Two of the three elements must meet the threshold for a given MDM level.

⚠  Compliance Reminder: 2-of-3 MDM Rule

A common misunderstanding: meeting ALL THREE MDM elements at a given level is not required only two of the three must meet the threshold. However, each element that IS documented must genuinely reflect the complexity claimed. Documentation that lists two stable chronic conditions (meeting the moderate ‘Problems’ threshold) but then describes no data reviewed and minimal risk management does not support 99214 because only one element meets the moderate threshold.

06 — Time-Based Coding Guide

Any established patient office visit from 99212 through 99215 may be billed based on total time on the date of encounter if the provider prefers time over MDM as the basis. Total time includes all clinician time directly related to the encounter on that date, whether or not face-to-face with the patient.

💰 Revenue Tip: Time-Based Billing Can Capture Legitimate Higher-Level Codes

Many physicians undercode because their MDM documentation doesn’t fully reflect the complexity of their thinking. But when a provider spends 35–40 minutes managing a complex patient reviewing labs from the hospital, calling a consultant, updating a care plan, and documenting all of it time-based coding may support 99214 or even 99215 even if the MDM documentation is incomplete. If time is used as the basis, the total minutes must be explicitly stated in the note. If it’s not in the record, it didn’t count for billing purposes.

07 — Step-by-Step E/M Billing Workflow

#	Stage	Action & Compliance Note
01	Confirm Established Patient Status	Verify that the patient has been seen in the same group practice and specialty within the past 3 years; if not, new patient E/M codes (99202–99205) apply
02	Review Documentation Before Coding	Read the full encounter note problems addressed, data reviewed, risk elements, and any time documentation before selecting a code
03	Choose Basis: MDM or Time	Determine whether MDM or total time provides stronger support for the encounter; document the chosen basis explicitly in the note if time is used
04	Apply MDM Table (if MDM-based)	Map the encounter’s problems, data, and risk to the MDM table; confirm that at least two of three elements meet the threshold for the selected code
05	Verify Diagnosis-Code Linkage	Confirm that the ICD-10 codes on the claim match the problems documented as addressed during the encounter
06	Check for Same-Day Procedure Modifier 25	If a procedure is also billed on the same date, confirm the E/M note documents a separately significant service and apply modifier 25 to the E/M code
07	Verify Payer Requirements	Check payer-specific E/M policies, especially for Medicare Advantage plans, which may have additional documentation or authorization requirements
08	Submit Clean Claim	Confirm rendering provider NPI, place of service code (POS 11 for office), and diagnosis-code linkage before electronic submission
09	Monitor Denial Trends	Track E/M denials by code level and denial reason; identify patterns in documentation gaps or code-level distribution that suggest a systemic issue
10	Conduct Quarterly Coding Audits	Randomly audit E/M claims to confirm code distribution is consistent with clinical complexity and that documentation supports the codes reported

08 — Documentation Mistakes That Cause E/M Denials

These are the documentation errors that generate the highest volume of E/M denials and audit findings. Most are preventable with the right workflows and provider education.

Documentation Mistake	Financial Impact	Prevention Strategy
Upcoding: 99214/99215 without supporting MDM or time	Recoupment on audit; OIG investigation risk if pattern found	Quarterly internal coding audits; MDM tool at point of care
Downcoding: 99212/99213 when 99214 is supported	Lost revenue on every qualifying visit — compounding annually	Coder review of notes for legitimate upgrade opportunities
Copy-forward notes (cloning)	Notes that don’t reflect current encounter; per-encounter audit risk	EHR attestation requirement; provider education on note specificity
No MDM documentation at all	Code selection cannot be defended; default to lowest supported level	Train providers on documenting all three MDM elements explicitly
Time documented without total minutes	Time-based coding invalid; auditor uses MDM instead, often lower	Require specific minute documentation when time is the basis
Missing data element documentation	MDM data column left empty; moderate and high levels lose one of three elements	Template prompts for data reviewed, test interpretation, or provider discussions
Risk element not documented	Prescription drug management or procedure risk not reflected	Explicitly document management decisions and associated risk rationale
Modifier 25 missing on same-day procedures	E/M bundled with procedure and denied	Build modifier 25 into billing system default when E/M + procedure same date
Wrong diagnosis on claim vs. note	Medical necessity denial; code mismatch	Coder cross-references ICD-10 claim against problems documented in note
99211 billed with no documentation	Service billed but not documented; audit finding	Require nursing visit note for every 99211 billed

09 — Reimbursement Considerations for 2026

We don’t publish specific reimbursement dollar amounts in this guide — MPFS rates are updated annually by CMS, GPCI-adjusted by geography, and commercial rates vary by contract. What we can tell you is what actually determines how much your practice collects on E/M office visits.

Reimbursement Factor	How It Affects 99211–99215 Revenue
Medicare Physician Fee Schedule (MPFS)	E/M codes are paid under the MPFS with work, practice expense, and malpractice components. GPCI adjustments vary by location. Verify current rates via the CMS fee schedule lookup tool annually.
Code Level Distribution	The single highest-impact revenue factor is whether your practice is capturing the right code level for each encounter. Systematic downcoding is as significant a revenue problem as systematic upcoding is a compliance problem.
Documentation Quality on Audit	Clean payment doesn’t guarantee audit survival. Post-payment audit recoupment for E/M codes is common. Documentation quality determines whether paid claims are recovered.
Commercial Payer Contracts	Commercial payers set E/M rates as percentages of Medicare or fixed schedules. Some payers have additional documentation requirements beyond CMS guidelines. Verify your contracts annually.
Modifier 25 Utilization	Proper use of modifier 25 when E/M and procedures are both billed on the same date captures legitimate E/M revenue that would otherwise be bundled and denied.
Incident-to Billing (Medicare)	When 99211–99215 is billed incident-to the physician under Medicare, the incident-to rules must be met. Violations result in recoupment for all claims where the supervising physician wasn’t physically present in the suite.
2026 CMS Policy Updates	Monitor the annual CMS Medicare Physician Fee Schedule Final Rule for any E/M-specific policy changes, RVU adjustments, or documentation guidance updates that affect code values.

10 — Best Practices for Medical Practices

The practices that consistently perform well on E/M billing share one thing: they treat coding and documentation as an operational system, not an individual physician’s responsibility. These are the structural practices that make the difference.

📋 Conduct Quarterly E/M Coding Audits

Pull a random sample of 20–30 E/M claims each quarter and review them for: (1) code-level support by MDM or time; (2) documentation completeness across all MDM elements; (3) correct ICD-10 linkage; (4) modifier 25 use where applicable. Quarterly audits catch systemic issues before payers do — and the cost of a proactive audit is a fraction of the cost of a retrospective payer audit.

🏫 Provide Providers with an MDM Reference Tool

The 2021+ MDM criteria are not intuitive, especially the data column. A simple one-page reference card mapping common clinical scenarios to MDM levels posted in each exam room or integrated into the EHR workflow consistently improves documentation accuracy without adding significant provider time.

⏱  Train Providers on Time Documentation

When time is the better basis for code selection, the documentation required is minimal: the total minutes spent. Yet many providers don’t document time because no one explicitly told them to. A single training session explaining when to use time vs. MDM and how to document it routinely increases E/M revenue for practices with time-intensive encounters.

📊 Track E/M Code Distribution Across Providers

If one provider consistently bills 90% of visits at 99213 and another bills 90% at 99214, and both see similar patient populations, one of them likely needs education on code selection — in either direction. Comparing code distribution against the practice’s specialty benchmark is one of the most reliable early indicators of a systemic coding issue.

🔍 Review Payer Policies Annually

Medicare Advantage plans, Medicaid managed care programs, and commercial payers increasingly publish their own E/M documentation policies that may differ from the AMA’s national guidelines. Review your top five payers’ E/M policies annually and build any payer-specific requirements into your billing workflow. Policies that were current two years ago may have changed.

Frequently Asked Questions — CPT 99211–99215 Office Visit Billing

These questions address the most common knowledge gaps in E/M office visit coding. Answers reflect AMA/CMS 2021+ guidelines as in effect through 2026.

Frequently Asked Question	Expert Answer from MedCloudMD
What is CPT 99213 and when is it appropriate?	CPT 99213 is the established patient office visit code for low Medical Decision Making complexity — typically appropriate when the patient has two or more self-limited or minor problems, one stable chronic illness, or one acute uncomplicated illness or injury. Under time-based coding, 99213 covers 20–29 minutes of total time on the date of encounter. It is one of the most commonly billed E/M codes and one of the most frequently audited for documentation support.
What is the difference between CPT 99214 and 99215?	CPT 99214 requires moderate MDM: typically involving one or more chronic illnesses with exacerbation, two or more stable chronic illnesses, or an undiagnosed new problem with uncertain prognosis. CPT 99215 requires high MDM: involving one or more chronic illnesses with severe exacerbation, or a new problem with potential threat to life or bodily function. Under time-based coding, 99214 covers 30–39 minutes and 99215 covers 40–54 minutes of total encounter time.
When should CPT 99211 be billed?	CPT 99211 is appropriate for established patient visits that do not require the presence of a qualified healthcare professional — typically a nurse or medical assistant visit for tasks like blood pressure checks, test results review, or suture removal. Under incident-to billing for Medicare, the supervising physician must be in the office suite during the service. 99211 does not require MDM documentation but the service must be clearly documented.
Can office visits be billed based on time?	Yes. Under current AMA/CMS guidelines in effect through 2026, any established patient office visit code (99212–99215) may be billed based on total time spent on the date of the encounter — this includes pre-visit preparation, face-to-face time with the patient, ordering and reviewing tests, and documentation time. The total time must be documented in the medical record. If time is used as the basis for code selection, the specific total minutes must be stated.
What documentation is required for E/M office visit coding?	Under current guidelines, code selection is based on either MDM or total time. MDM documentation requires: (1) the number and nature of problems addressed; (2) the amount and complexity of data reviewed and ordered; and (3) the risk of complications and/or morbidity or mortality of patient management. History and physical examination may still be documented but are no longer required for E/M level selection under the 2021+ guidelines.
How do payers determine reimbursement for 99211–99215?	Medicare reimburses these codes under the Medicare Physician Fee Schedule (MPFS) with GPCI geographic adjustment. Commercial payers set their own rates, often referenced as a percentage of Medicare. Documentation quality directly affects whether a claim is paid on first submission or denied; underpayment or recoupment risk on audit is directly tied to whether the documented MDM or time supports the code reported.
What are the most common coding mistakes for 99211–99215?	The most common errors are: upcoding (reporting 99214 or 99215 without adequate MDM or time documentation); downcoding (reporting 99212 or 99213 when documentation would support a higher level, leaving revenue uncaptured); copy-forward notes that don’t reflect the current encounter; and using the wrong basis (claiming MDM level but only documenting a complaint and exam without addressing MDM elements).
How can practices reduce E/M coding denials?	Key steps: (1) ensure all three MDM elements problems, data, and risk are explicitly documented when MDM is the basis; (2) document total time in minutes when time-based billing is used; (3) conduct quarterly internal coding audits; (4) provide providers with MDM-level reference guides; (5) review the top denial reason codes monthly and address them at the documentation workflow level, not just claim by claim.
Is it compliant to always bill 99213 or 99214 as a default?	No. This is one of the patterns most commonly identified in E/M coding audits. Code selection must be individually determined for each encounter based on the actual MDM complexity or total time documented. A practice that consistently bills the same code level regardless of clinical variation creates a pattern that payers and auditors recognize as a upcoding or downcoding risk, depending on the code selected.
Can 99211–99215 be reported on the same day as a procedure?	In many cases, yes — but a separately significant E/M service must be documented, and modifier 25 must be appended to the E/M code to indicate that the visit was distinct from the procedure performed on the same date. Without modifier 25, the E/M will typically be bundled with the procedure and denied. The E/M documentation must clearly show that it addresses a problem separate from the procedure.
