CPT Codes 99202–99205: The 2026 Complete Guide to New Patient Office Visit Billing, Documentation & Reimbursement

Schedule Your Free Consultation

New patient office visits are among the most billed and most frequently miscoded encounters in outpatient medicine. Whether a provider is selecting CPT 99202 for a straightforward complaint or documenting what should be a 99205, an error in either direction carries real consequences: downcoding leaves legitimate revenue on the table, overcoding invites payer audits, and missing or unsupported documentation triggers denials that delay your cash flow for weeks.

In 2026, with CMS continuing to refine its Medical Decision Making (MDM) framework and commercial payers deploying AI-assisted claim review systems, getting these four codes right is not optional it is foundational to a healthy revenue cycle. Our billing specialists at MedCloudMD work every day with physicians, nephrologists, primary care providers, and specialty practices to ensure every new patient encounter is coded accurately, documented compliantly, and reimbursed at the correct level.

This guide gives you a practical, authoritative framework for CPT codes 99202 through 99205 from MDM logic and time-based thresholds to nephrology-specific scenarios, real-world billing examples, compliance safeguards, and documentation strategies that prevent denials before they happen.

💡  Did You Know?

CPT code 99201 was permanently deleted on January 1, 2021, and remains invalid in 2026. If your superbill templates or charge capture tools still list this code, every claim attached to it will be denied automatically. Auditing your charge capture tools regularly is a simple step that prevents unnecessary revenue loss.

Section 1: What Are CPT Codes 99202–99205?

CPT codes 99202 through 99205 are the Evaluation and Management (E/M) codes assigned to new patient office or outpatient visits. Published and maintained by the American Medical Association (AMA), these codes apply to encounters in physician offices, clinic settings, and outpatient facilities where a qualified clinician is performing an evaluation of a new patient.

Since the landmark 2021 E/M documentation revisions revisions that CMS has maintained and further refined through 2026 — code level selection for these visits is no longer driven by the volume of history elements or physical exam findings. Today, the correct code is determined by Medical Decision Making (MDM) or by total physician time on the date of the encounter. That shift alone has created significant confusion — and significant compliance risk for practices that have not updated their documentation and coding workflows.

Who Qualifies as a New Patient?

The AMA defines a new patient as an individual who has not received any professional services from the same physician, or another physician of the same specialty and subspecialty who belongs to the same group practice, within the past three years. This definition is precise and strictly enforced billing a returning patient as new is one of the most frequently audited E/M distinctions, and it can constitute fraudulent billing if done incorrectly.

Our billing team at MedCloudMD builds patient status verification directly into the front-end registration workflow specifically to prevent this error before the claim is ever submitted.

CPT Code Quick Reference: 99202–99205

Note: Total time ranges reflect 2026 CMS guidelines for total physician time on the date of the encounter — not face-to-face time alone. CPT 99201 was deleted in 2021 and must not be used.

Section 2: Individual Code Breakdowns

CPT 99202 — Straightforward Medical Decision Making

CPT 99202 applies to new patient visits involving minor or self-limited problems that require minimal data review and carry low-risk management decisions. This is the entry-level new patient code not the simplest imaginable visit, but one where clinical complexity is genuinely low and the management decision requires little independent judgment.

🩺  Typical Presentations

Minor upper respiratory infection, uncomplicated rash, a single-medication refill for a stable and well-documented condition with no new complications, or a routine preventive evaluation with no significant findings.

Billing Tip: Over-documenting does not justify billing a higher code level. If the MDM is straightforward, 99202 is the correct code regardless of how detailed the note is. Billing 99203 when 99202 is appropriate is a form of upcoding that carries audit risk.

CPT 99203 — Low Medical Decision Making

CPT 99203 applies to new patient visits involving low-complexity problems. At least one low-complexity acute illness or injury must be addressed, or a single stable chronic condition may qualify if the management decision reflects low complexity.

Common clinical scenarios include a urinary tract infection in an otherwise healthy patient, mild hypertension newly identified without target organ damage, or a patient new to the practice with one well-managed chronic condition requiring prescription renewal.

⚠️  Common Coding Mistake

Providers sometimes select 99203 based on the number of organ systems reviewed in the physical exam or the number of history elements documented. Under the 2021–2026 E/M framework, documentation volume no longer drives code levels. MDM is the driver. Reviewing 10 organ systems does not make a visit 99203 if the problem and management are straightforward.

CPT 99204 — Moderate Medical Decision Making

CPT 99204 is one of the most frequently billed new patient codes in adult medicine and specialty care — and also one of the most frequently audited. It applies to encounters with moderate MDM, typically involving multiple chronic conditions, an undiagnosed problem with uncertain prognosis, or prescription drug management with meaningful clinical complexity.

Documentation Checklist — What Your CPT 99204 Note Must Support:

✔  Chief complaint clearly stated in clinical or patient-reported terms

✔  At least one moderate-complexity problem identified (e.g., exacerbating chronic condition, new undiagnosed problem with uncertain prognosis)

✔  Independent data review documented: labs, imaging, or external records reviewed AND interpreted by the physician

✔  Moderate-risk management decision supported — prescription drug management is the most common qualifier

✔  Rationale for tests ordered is documented in the note

✔  Treatment plan with clinical reasoning and follow-up timeline provided

✔  Patient education and counseling documented if used toward total time billing

✔  ICD-10 codes selected that align with and support the documented problems

CPT 99205 — High Medical Decision Making

CPT 99205 is the highest-level new patient office visit code and should only be selected when the documentation genuinely supports high-complexity medical decision making. It is also the code most likely to be reviewed, audited, and denied without sufficient clinical justification.

🚨  Compliance Alert

CPT 99205 is among the most audited codes in outpatient E/M billing. The OIG and commercial payers specifically flag practices with high concentrations of 99205 without documentation that supports it. If your practice consistently bills 99205 for new patients, your clinical notes must consistently reflect the high-level decision making that justifies it or you face audit risk, repayment demands, and potential exclusion.

High MDM indicators that support CPT 99205:

✔  Severe exacerbation or rapid progression of a chronic illness

✔  Acute illness posing a potential threat to life or bodily function

✔  Drug therapy requiring intensive monitoring (e.g., anticoagulants, immunosuppressants, ESAs)

✔  Documented consideration of hospitalization or escalation of care level

✔  Extensive independent review of external records, test results, or specialist consultations on the date of service

Section 3: 2026 Documentation Guidelines — MDM and Time-Based Coding

Two pathways exist for determining the correct CPT code level for a new patient visit: Medical Decision Making (MDM) and total physician time. CMS has maintained this dual-pathway model through 2026 with ongoing AMA guidance on specialty-specific applications and edge cases.

Medical Decision Making (MDM) — Three-Element Framework

MDM is composed of three elements. To qualify for a given code level, at least two of the three elements must meet or exceed the requirements for that level:

①  Number and complexity of problems addressed at the encounter

②  Amount and complexity of data reviewed and analyzed

③  Risk of complications and/or morbidity or mortality of patient management

Two of the three MDM elements must meet or exceed the threshold for the selected code level. A code is not justified simply because one element reaches a higher threshold.

Time-Based Coding — 2026 Rules and Documentation Requirements

When total time is used as the basis for code selection, the physician or other qualified healthcare professional must document total time spent on the date of the encounter in minutes. This includes all time described below not just face-to-face contact.

✅  What Counts Toward Total Time

✔  Face-to-face time with the patient and/or family or caregiver

✔  Reviewing test results and external records before the visit

✔  Ordering tests and reviewing results on the date of service

✔  Writing and completing the clinical note

✔  Care coordination performed on the same calendar date

✔  Counseling and education provided to patient or caregiver

❌  What Does NOT Count Toward Total Time

✖  Time spent by clinical staff (MAs, nurses, technicians)

✖  Activities performed on a different calendar date

✖  Travel time to or from the office or clinic

✖  Patient waiting room time or administrative intake time

2026 Time Thresholds — New Patient Office Visits

CPT Code	Minimum Total Time	Maximum Total Time
99202	15 minutes	29 minutes
99203	30 minutes	44 minutes
99204	45 minutes	59 minutes
99205	60 minutes	74 minutes
Important: The physician must explicitly state the total time in minutes in the note. Phrases like 'Total time spent: 47 minutes' are acceptable. Vague entries like 'significant time' are not sufficient for payer review and will not withstand audit scrutiny.

Section 4: Complete Documentation Checklist for CPT 99202–99205

📋  Every New Patient Note Must Address the Following:

✔  Chief Complaint — Reason for the visit clearly stated in the patient's own words or a clinical summary

✔  History of Present Illness (HPI) — Relevant history addressing the presenting problem(s), including onset, duration, and relevant context

✔  Assessment — Diagnoses or clinical impressions with supporting rationale and differential considerations where applicable

✔  Medical Decision Making — Explicit narrative of all three MDM elements relevant to this encounter

✔  Diagnostic Review — Labs, imaging, or external records reviewed with physician interpretation noted separately

✔  Lab Results — Specific values referenced and interpreted; 'labs reviewed' alone is insufficient

✔  Imaging — Report findings documented or test ordered with clinical rationale stated

✔  Treatment Plan — Management decisions, prescriptions, referrals, and procedural plans with supporting reasoning

✔  Follow-Up — Specific timeframe and return instructions documented

✔  Patient Counseling — Topics covered and time spent if used toward time-based coding

✔  Care Coordination — Nature and time of coordination documented if that time is being counted

Section 5: Step-by-Step Billing Workflow for New Patient Office Visits

A clean, compliant claim for CPT 99202–99205 depends on every step of the billing workflow functioning correctly. Our billing team at MedCloudMD uses a structured, end-to-end workflow that reduces error rates, accelerates reimbursement timelines, and keeps practices protected from compliance exposure:

01	Patient Registration  — Verify identity, demographics, and critically confirm new vs. established patient status before the encounter begins
02	Insurance Verification  — Confirm active coverage, new patient benefits, applicable deductibles, and whether prior authorization is required
03	Medical Documentation  — Provider completes a thorough note that addresses MDM explicitly or documents total time in minutes accurately
04	MDM or Time Review  — Billing team reviews the note for MDM element sufficiency and code-level alignment before CPT selection
05	Correct CPT Selection  — Assign 99202–99205 based on two-of-three MDM elements or documented total time; verify no 99201 usage
06	ICD-10 Assignment  — Select diagnosis codes that support medical necessity and align logically with the CPT code level selected
07	Modifier Review  — Confirm modifiers (e.g., -25 if E/M is billed same day as procedure) are applied correctly and are payer-compliant
08	Claim Submission  — Submit clean claim via electronic channel with all required fields complete and no errors in demographic or coding data
09	Payment Posting & Reconciliation  — Post EOBs and remittances accurately; flag underpayments and contractual variances for follow-up
10	Denial Management  — Analyze denial reason codes, appeal where appropriate, and adjust workflows to prevent the same denial from recurring

Section 6: Common Billing Errors and How to Prevent Them

Section 7: Reimbursement Overview — 2026 Considerations

Actual reimbursement for CPT codes 99202–99205 varies significantly by payer, geography, and contracted rates. We do not publish specific dollar amounts because they change annually and differ substantially across Medicare Administrative Contractors (MACs), commercial plans, and managed care organizations.

What is consistent is the relationship between code complexity and reimbursement: higher-complexity codes carry meaningfully higher Relative Value Units (RVUs), which translate directly into higher payment. Every dollar of undercoding is direct revenue loss. Every dollar of overcoding creates compliance liability.

Key Reimbursement Factors to Understand in 2026

✔  Medicare RVUs and GPCI: CMS assigns Work, Practice Expense, and Malpractice RVUs to each code. These are multiplied by the Conversion Factor and adjusted by your region's Geographic Practice Cost Index (GPCI). Higher codes = higher RVUs = higher payment.

✔  Commercial Payer Contracts: Most commercial payers reimburse at a percentage of Medicare or via independently negotiated fee schedules. Rates vary widely — verify your contracted amounts against what you are actually receiving.

✔  Clean Claim Submission: A clean claim submitted without errors is the single most reliable way to protect your reimbursement timeline. A denied claim costs twice — once to work and once in delayed or lost cash flow.

✔  Modifier Accuracy: Certain billing scenarios require modifiers (e.g., Modifier -25 when an E/M is billed same-day as a minor procedure). Missing or misused modifiers are a leading cause of E/M denials.

✔  Timely Filing Windows: Every payer has a timely filing deadline. Missing it forfeits the claim entirely, regardless of how accurately it was coded or how medically necessary the service was.

Section 8: Compliance & Audit Risks in 2026

🚨  OIG Work Plan — New Patient E/M Codes

The Office of Inspector General (OIG) consistently includes new patient E/M coding in its annual Work Plan. Practices with high concentrations of 99204 and 99205 — particularly those without documentation that clearly supports those levels — are statistically more likely to be selected for focused medical record review or full-scale audit.

Compliance risks your practice must actively manage in 2026:

✔  Upcoding: Billing a code level higher than the documentation supports. This is the most audited E/M risk and can result in repayment demands, False Claims Act exposure, and exclusion from Medicare and Medicaid.

✔  Downcoding: Systematically billing lower codes than warranted. While less scrutinized than upcoding, it represents real and recoverable revenue loss and may indicate documentation or training gaps.

✔  Medical Necessity: Every service billed must be medically necessary. The ICD-10 diagnosis must align with the CPT code level and explain why the visit was clinically warranted at that level of complexity.

✔  Record Retention: CMS requires Medicare records to be retained for at least seven years. Many states impose longer periods. Inability to produce records during an audit is treated as lack of documentation.

✔  AI-Assisted Payer Auditing: Commercial payers now use AI tools to detect template-heavy, copy-paste, or statistically aberrant documentation patterns. Each note must genuinely reflect the individual patient encounter.

Section 9: Specialty Spotlight — Nephrology Practices

New patient office visits in nephrology are among the most documentation-intensive encounters in outpatient medicine. Nephrologists routinely evaluate patients with layered, interconnected conditions CKD, hypertension, anemia of chronic disease, electrolyte imbalances, proteinuria, and high-risk medication management all of which must be individually addressed and collectively documented to justify the appropriate code level.

Clinical Condition	Coding Implication for CPT 99202–99205
Chronic Kidney Disease (CKD Stages 1–5)	Multi-problem evaluation with significant data complexity typically supports 99204 or 99205
Hypertension with Renal Involvement	Moderate MDM baseline; escalates to high if target organ damage (cardiac, renal) is present and documented
Acute Kidney Injury (AKI)	Severity, underlying cause, and clinical risk often support high MDM may justify 99205
Electrolyte Disorders (Hyperkalemia, Hyponatremia, etc.)	Complexity depends on severity and etiology; life-threatening cases clearly support 99205
Proteinuria / Hematuria Workup	New undiagnosed problem with uncertain prognosis — typically moderate MDM, may escalate based on data reviewed
Dialysis Evaluation (Pre-ESRD or Initiation)	Complex multi-system review with high data intensity typically supports 99205
Kidney Function Assessment with Multi-System Review	MDM level determined by the number of problems, data intensity, and risk of management decisions
High-Risk Medication Management (Tacrolimus, ESAs, Warfarin)	Drug therapy requiring intensive monitoring is an explicit high-risk management qualifier under 2026 MDM rules

Nephrology billing carries complexity that general billing teams are often not trained to navigate. Patients frequently present with conditions managed across multiple specialties, and the documentation must demonstrate independent review of external data, laboratory trends, and prior consultation notes. A nephrologist who independently interprets external labs, reviews a hospital discharge summary, and discusses findings with a cardiologist all on the same date of service may have sufficient data complexity alone to justify a moderate or high MDM level.

Section 10: Real-World Billing Scenarios

The following scenarios are based on representative clinical presentations commonly encountered in nephrology and internal medicine. No patient-identifying information is used. These examples are intended to illustrate how MDM elements interact in real documentation contexts and how the correct code is selected.

Scenario 1: New Patient with Elevated Creatinine and Suspected CKD

Patient Presentation: A 58-year-old male, new to the practice, referred by his PCP for elevated creatinine on three consecutive lab draws. History includes hypertension and Type 2 diabetes, both under management with primary care.

Medical Decision Making: The nephrologist independently reviews external labs, a prior PCP summary note, and an old renal ultrasound. Two chronic conditions are actively addressed with potential CKD progression. New renal function panel ordered. ACE inhibitor dose reviewed and adjusted. Management plan documents both conditions and the clinical rationale.

Correct CPT: 99204 — Moderate MDM (Two chronic conditions addressed; independent external data review; prescription drug management)

Documentation Tip: Explicitly state in the note that external records were independently reviewed and interpreted by the physician — not simply acknowledged as received. This distinction is critical for the data element of MDM.

Common Denial Risk: External records referenced in the note but not stated as independently reviewed and interpreted by the physician. This collapses the data element and may drop the encounter to 99203.

Scenario 2: New Patient with Life-Threatening Hyperkalemia

Patient Presentation: A 72-year-old female, new patient, referred directly from the ED with lab-confirmed hyperkalemia (K+ 6.4 mEq/L). Currently on an ACE inhibitor for hypertension with recent dose increase by PCP.

Medical Decision Making: The nephrologist evaluates cardiac risk, reviews the medication list, adjusts the ACE inhibitor, orders repeat potassium and EKG review, and documents an explicit decision regarding hospitalization versus outpatient management with 48-hour follow-up.

Correct CPT: 99205 — High MDM (Acute illness posing threat to life; high-risk management decision including documented hospitalization consideration)

Documentation Tip: Include this exact type of sentence in the note: 'Hospitalization was considered and deferred based on patient's hemodynamic stability and response to initial management; follow-up within 48 hours arranged.' This explicitly documents the high-risk decision.

Common Denial Risk: Payer requests medical records to validate severity. The potassium level, EKG result, and the hospitalization decision rationale must all be clearly documented or the claim will be downcoded or denied.

Frequently Asked Questions: CPT 99202–99205

The following questions reflect what physicians, coders, and practice managers most frequently ask about new patient E/M billing. Answers reflect current AMA CPT guidance and CMS documentation requirements as of 2026.

Q1:  What is CPT 99202 used for?

CPT 99202 is used for new patient office visits involving straightforward MDM. It applies when the presenting problem is minor or self-limited, data review is minimal, and the management plan carries low risk. Common examples include a minor infection, an uncomplicated rash, or a single-medication refill for a stable, well-documented chronic condition.

Q2:  What is the difference between CPT 99203 and CPT 99204?

CPT 99203 reflects low-complexity MDM typically one low-complexity acute illness or a single stable chronic condition. CPT 99204 requires moderate-complexity MDM usually two or more stable chronic conditions, one chronic condition with mild exacerbation, or an undiagnosed new problem with uncertain prognosis. The data and risk thresholds are meaningfully higher for 99204, and prescription drug management must be explicitly supported in the note.

Q3:  How is CPT 99205 justified?

CPT 99205 requires high-complexity MDM, meaning at least two of the three MDM elements must reach the high threshold. Indicators include a severe exacerbation of a chronic illness, an acute illness posing risk to life or bodily function, drug therapy requiring intensive monitoring, or a documented decision regarding hospitalization. The physician's note must explicitly narrate the clinical reasoning listing diagnoses alone is not sufficient.

Q4:  Can total physician time be used to select the CPT code?

Yes. Under the 2021–2026 E/M guidelines, total physician time on the date of the encounter can be the sole basis for code selection. This includes preparatory review, face-to-face time, documentation time, care coordination, and patient education all on the same calendar date. The physician must document the total time in minutes explicitly in the note.

Q5:  What defines a 'new patient' for billing purposes?

Per AMA definition, a new patient is someone who has not received professional services from the same physician, or another physician of the same specialty and subspecialty within the same group practice, within the past three years. This applies regardless of whether a patient chart exists in your system the three-year window is what matters.

Q6:  Are history and physical exam still required in 2026?

History and physical exam are no longer drivers of E/M code levels under the current guidelines. However, a medically appropriate history and exam are still expected and should be documented as clinically warranted. Their complete absence in a complex note particularly for 99204 or 99205 may raise red flags during a payer audit or OIG review.

Q7:  Can nurse practitioners and physician assistants bill CPT 99202–99205?

Yes. NPs and PAs may bill these codes when operating within their scope of practice, state law, and payer credentialing requirements. For new patients specifically, incident-to billing rules do not apply the encounter must be billed under the NP's or PA's own NPI. Billing a new patient encounter as incident-to the supervising physician is an audit risk.

Q8:  How do Medicare and commercial payers differ for these codes?

Medicare follows CMS guidelines with RVU-based payment adjusted by the Geographic Practice Cost Index (GPCI) for your location. Commercial payers typically contract at a percentage of Medicare or via their own fee schedules and may apply additional medical necessity or documentation requirements beyond CMS. Never assume Medicare rules apply universally to commercial payer billing.

Q9:  What documentation supports high-level MDM for CPT 99205?

High MDM documentation requires: a problem that is severe or life-threatening, extensive data reviewed (independent interpretation of test results, external records, or specialist consultation on the same date), and a high-risk management decision (intensive drug monitoring, hospitalization consideration, or surgery discussion). The physician must narrate the clinical reasoning explicitly 'complex patient' is not a substitute.

Q10:  What are the most common denial reasons for CPT 99202–99205?

The most frequent denials include: incorrect patient status (established patient billed as new), documentation insufficient to support the code level selected, missing ICD-10 to CPT alignment, missing or incorrect modifiers when procedures are billed alongside E/M services, and timely filing violations. Our team monitors denial patterns monthly and adjusts workflows proactively to address root causes before they compound.
