Of all the billing errors we see when we audit cardiology and outpatient practice accounts, undercoding on new patient E/M visits is the most consistent, most costly, and most avoidable. Providers work through genuinely complex new patient evaluations multiple chronic conditions, layered diagnostic data, high-risk treatment decisions and then watch that clinical work get billed at 99202 or 99203 because the documentation wasn't structured to support a higher level.
CPT codes 99202 through 99205 govern new patient office visits, and getting them right in 2026 requires understanding two things that most practices still struggle with: how medical decision making (MDM) is actually defined and documented, and how time-based billing works as a legitimate alternative. Confuse those two pathways, pick the wrong one for the encounter, or document in a way that doesn't support your selected code and you've just given back revenue you clinically earned.
At MedCloud MD, we've rebuilt E/M coding workflows for practices across the country. This guide explains exactly how 99202–99205 work in 2026, where the revenue is being lost, and what it takes to recover it without adding clinical burden or audit risk.
40% of new patient visits are routinely undercoded | $220K+ avg. annual revenue loss per 3-physician practice | 78% of E/M denials tied to fixable documentation gaps |
💡 Did You Know? CMS data consistently shows that the majority of E/M undercoding isn't happening because providers are being cautious it's happening because billing teams and providers don't share the same understanding of what documentation is required to support each code level. The 2021 AMA E/M guideline revisions made higher-level coding more achievable than ever. But those revisions only help practices whose billing infrastructure actually applies them. In 2026, failure to optimize E/M coding on new patient visits is one of the single largest, most addressable revenue drains in outpatient medicine. |
1. What Are CPT Codes 99202–99205?
These four CPT codes represent new patient office or outpatient evaluation and management (E/M) visits. A 'new patient' under AMA definition is any patient who has not received professional services from the physician (or a physician of the same specialty and group) within the past three years. First encounter or no recent history these are the codes that apply.
Since the 2021 AMA E/M revisions took full effect, there are two legitimate pathways for selecting the appropriate code level: Medical Decision Making (MDM) the complexity of the clinical decisions made during the visit or total time spent on the encounter on the date of service. Providers can choose whichever pathway produces the better-supported, higher-level code for that specific encounter.
CPT 99201 was deleted as of January 2021. The current active range for new patient visits starts at 99202 (straightforward MDM) and tops out at 99205 (high complexity MDM). Here's how they break down:
2. 📊 99202–99205 Comparison Table — The Full Breakdown
This is the table your entire billing team should have memorized. Code selection starts here:
3. Understanding Medical Decision Making — The Engine of Accurate E/M Coding
MDM is where most E/M coding complexity lives and where most revenue is lost. There are three components to MDM: the number and complexity of problems addressed, the amount and complexity of data reviewed and analyzed, and the risk of complications and/or morbidity or mortality. To select a code based on MDM, two of the three elements must meet the threshold for that level.
Breaking Down Each MDM Component in Plain Terms
Component 1 — Problems Addressed
This is about what clinical problems were actively managed during the visit. A 'problem' in MDM terms includes any condition the physician directly evaluated, addressed, or made a treatment decision about. New, undiagnosed conditions score higher. Stable, well-controlled chronic conditions score lower. Cardiology patients almost always have multiple active problems which is exactly why undercoding at 99202 or 99203 in a cardiology setting is almost always a documentation failure, not a clinical one.
Component 2 — Amount & Complexity of Data
This covers the data the physician reviewed, ordered, or analyzed to inform clinical decisions. Ordering or reviewing diagnostic tests counts. Reviewing external records counts. Independently interpreting results (without relying solely on a formal reading by another provider) counts. Each of these contributes to your MDM data score and each needs to be documented in the note to be counted.
Component 3 — Risk of Complications
Risk is driven by the management options selected and the patient's condition. Prescribing a new chronic medication? That's moderate risk. Adding a medication requiring intensive monitoring? High risk. Ordering a minor procedure with no identified risk factors? Low. For most cardiology new patient visits, the treatment decisions — new antihypertensives, anticoagulants, antiarrhythmics, referrals for procedures — naturally push risk to moderate or high. But only if the note captures the decision explicitly.
✅ The MDM Documentation Rule That Changes Everything Your documentation doesn't need to mention 'medical decision making.' It needs to show the clinical thinking in a way that maps to MDM components. A note that describes the problems addressed, identifies what data was reviewed and how it informed the assessment, and explains the rationale for the treatment plan is an MDM-supporting note — even without using the phrase 'MDM'. |
4. Time-Based Billing for 99202–99205 — When to Use It and How
Since 2021, total time on the date of service not just face-to-face time counts toward E/M code selection. This includes pre-visit preparation, reviewing records, ordering tests, documentation, care coordination, and counseling, as long as it happens on the same calendar date as the encounter.
Time-based billing is often the better path when: the visit involves extensive counseling, complex care coordination, or prolonged documentation time that pushes the total encounter beyond MDM complexity thresholds. It's also valuable when documentation of MDM components is incomplete but time is well-documented.
5. 🧾 Documentation Checklist — What Every New Patient E/M Note Needs
Whether you're coding by MDM or time, your note must support the code level you select. Here's the complete checklist for 2026-compliant new patient E/M documentation:
Documentation Element | Required For | Key Compliance Point |
Chief complaint / reason for visit | All levels (99202–99205) | Must be clearly stated — establishes the encounter's clinical context |
History of present illness (HPI) | All levels | Depth should match visit complexity; brief for 99202, detailed for 99205 |
Relevant past medical, family, social history (PFSH) | 99203+ (MDM-based) | Not every element needed — document what's relevant to the presenting problems |
Review of systems (ROS) | Encouraged — improves problem documentation | Not required by 2021 guidelines for E/M level selection, but valuable context |
Physical examination | Documents clinical findings | Not required for code selection under 2021 guidelines — but documents care quality |
Assessment & plan — problems addressed | ALL levels (MDM Component 1) | List every problem actively managed; don't omit addressed conditions |
Data reviewed and analyzed | Moderate & High (MDM Component 2) | Name specific tests ordered/reviewed; document independent interpretations |
Treatment decision rationale & risk | All MDM-based coding | Document why treatment was selected; note monitoring requirements for new medications |
Total time (if time-based billing) | Time-based billing only | State total time; describe activities performed during that time |
Date of service | All claims | Obvious but commonly missing on handwritten or rushed documentation |
Provider signature and credentials | All claims | Unsigned notes are legally and financially void |
ICD-10 diagnosis code linkage | All claims | All billed codes must link to supporting diagnoses — code specificity matters |
✅ Pro Tip: The Assessment & Plan Is Your Highest-Value Documentation Real Estate Under 2021 guidelines, the Assessment & Plan section does the most work for MDM-based coding. Every problem addressed, every test ordered and why, every treatment decision with its rationale — these all live in the A&P and directly map to MDM components. A well-structured A&P turns a 99203 into a justified 99204 or 99205 without adding a single word to the HPI or exam. |
6. 💰 Reimbursement Breakdown — What Each Code Is Worth in 2026
Reimbursement varies by geography, payer, and facility type. Here's a realistic national benchmark for 2026 and the revenue impact of consistently coding at the correct level:
📈 Revenue Impact Insight A three-physician cardiology group seeing 50 new patients per month and consistently coding one level lower than supported by clinical documentation is leaving $90,000–$150,000 on the table annually — not from fraud risk, not from complex billing strategy, but from documentation that doesn't reflect the clinical work already being performed. Closing that gap doesn't require seeing more patients. It requires documentation that actually captures what's already happening in the exam room. |
7. 🚫 The E/M Billing Mistakes That Are Quietly Draining Your Revenue
These are the patterns we find every time we audit a new client's E/M coding. Every single one is preventable but only once you know it's happening:
8. 📈 Revenue Optimization Strategies — Code at the Level You Earned
Strategy #1 — Train Providers on MDM Documentation, Not Just Code Selection
The most effective E/M revenue improvement we implement is shifting provider education from 'which code to pick' to 'how to document MDM support'. Providers who understand what Problem Complexity, Data, and Risk look like in their own notes start capturing them naturally without additional clinical burden or documentation time.
Strategy #2 — Implement a Pre-Bill MDM Review on New Patient Visits
Before any new patient claim goes out, have a coder or billing lead verify that the documentation supports the selected MDM level. For practices with high new patient volume, a 2-minute review per encounter — looking for two confirmed MDM components — can recover more than an hour's worth of physician fees per day.
Strategy #3 — Use Time-Based Billing Strategically, Not as a Default
Time-based billing is a genuine tool but it's most valuable for encounters where the total time clearly exceeds MDM thresholds, such as complex counseling visits or high coordination encounters. For standard complex cardiology new patient visits, MDM-based coding almost always produces the better-supported, higher-level result. Know when to apply each pathway.
Strategy #4 — Audit Your Top 20 New Patient Claims Monthly
Pull 20 new patient claims each month and review the selected code against the documentation. Look for two patterns: notes that support a higher code than was billed, and bare minimum documentation on high-code claims. The first reveals revenue opportunity. The second reveals audit exposure. Both need to be addressed — and monthly auditing surfaces them before they become costly problems.
Strategy #5 — Leverage the A&P Section as Your MDM Evidence Base
Teach providers to treat the Assessment & Plan as structured MDM documentation, not just a clinical summary. Each problem should be listed with its current status. Each test should reference the clinical question it was ordered to answer. Each treatment decision should note the reasoning and any monitoring requirements. A well-written A&P is the difference between 99204 and 99205 on most cardiology new patient visits.
💡 The Code Audit That Pays for Itself In virtually every new client E/M audit we perform, we find consistent undercoding on 20–40% of new patient visits. At the average Medicare reimbursement differential between 99203 and 99205, that translates to $100,000–$250,000 in annualized recoverable revenue for a mid-size practice — from documentation changes, not new patient volume. The audit itself takes a few hours. The revenue impact lasts the life of the practice. |
9. Why Cardiology Practices Lose More E/M Revenue Than Almost Any Other Specialty
Cardiologists see some of the most clinically complex new patients in all of outpatient medicine. Multiple chronic conditions, high-risk medication decisions, diagnostic data from multiple sources, life-function-threatening presentations — this is the clinical profile that MDM was designed to recognize and reward at the highest levels.
And yet cardiology ranks among the specialties with the highest rates of E/M undercoding — not because the clinical complexity isn't there, but because the documentation rarely captures it fully. Here's what drives that gap in cardiology specifically:
• Complex patients, rushed documentation: Cardiologists managing high patient volume don't always have time to document every MDM element they clinically addressed. The clinical work happens. The documentation trail doesn't.
• Diagnostic interpretation underdocumented: Cardiologists routinely review ECGs, echoes, Holter results, and stress tests from external facilities and form independent clinical judgments. This counts as high-value MDM data — but only when it's documented explicitly, which it often isn't.
• Multi-problem complexity miscounted: A new cardiology patient presenting with uncontrolled hypertension, newly diagnosed atrial fibrillation, and a history of CAD isn't a 'moderate complexity' visit — it's high complexity. But if the note lists these as separate past medical history items rather than actively addressed problems, the MDM problem score drops.
• High-risk treatment decisions go unnoted: Initiating anticoagulation, adding an antiarrhythmic, or referring for invasive workup carries high treatment risk under MDM. But unless the note documents the decision and its rationale explicitly, that risk level doesn't show up in the billing.
10. Before vs. After: What Optimized E/M Billing Actually Looks Like
The performance gap between reactive E/M coding and MedCloud MD-optimized E/M coding is consistent and measurable:
11. Why Outsourcing E/M Coding to Specialists Is a Revenue Decision, Not Just an Operational One
Managing 99202–99205 coding accurately across a high-volume cardiology practice isn't a task that falls naturally to generalist billing staff. It requires deep familiarity with the 2021 E/M guidelines, understanding of specialty-specific MDM patterns, the ability to read a clinical note and identify documentation gaps before the claim goes out, and the discipline to run monthly audits and act on what they find.
When that expertise isn't in the room, the default is undercoding which feels safe but costs significantly more than the compliance risk you think you're avoiding. Undercoding isn't conservative billing. It's revenue loss with a compliance rationale attached to it.
What In-House E/M Coding Typically Looks Like • Code selection driven by habit, not MDM analysis • Documentation gaps caught after denial — not before submission • No regular audit of code distribution vs. clinical complexity • Providers unclear on MDM documentation requirements • EHR auto-population used as documentation — not documentation support • Revenue opportunity invisible because no benchmark data exists | What MedCloud MD Delivers • MDM-based code selection on every new patient claim before submission • Pre-bill documentation review flagging gaps before denial • Monthly audit reports: code distribution, denial patterns, revenue recovery • Provider-level feedback on documentation improvements — no clinical burden added • Audit-ready documentation framework built into your billing workflow • Revenue benchmarking so you know what optimized coding is worth to your practice |

12. Frequently Asked Questions — CPT 99202–99205
Q: Can 99205 be billed regularly without audit risk?
Yes — when the documentation supports high-complexity MDM or when the total time on the date of service meets the 60-minute threshold. High-frequency 99205 billing only becomes an audit risk when the documentation doesn't support it. A cardiology new patient with multiple uncontrolled chronic conditions, complex diagnostic data, and a high-risk treatment decision routinely meets 99205 criteria. The risk is in the documentation, not the code.
Q: Do we need a physical exam for 99204 or 99205?
Not for code level selection under the 2021 AMA guidelines. Physical exam findings do not factor into E/M code selection under current guidelines the code is determined by MDM or time. However, documenting exam findings remains important for clinical continuity, risk management, and overall medical record quality.
Q: How do we know if we're undercoding?
The clearest signal is a code distribution that doesn't match your patient complexity. If a cardiology practice is billing 60–70% of new patients at 99203, that's almost certainly undercoding. A benchmark audit comparing your code distribution against your actual clinical documentation MDM element by element will confirm the gap and quantify the revenue opportunity.
Q: Can the same day E/M and a procedure both be billed?
Yes, with appropriate modifier -25 on the E/M code to indicate it represents a separately identifiable E/M service above and beyond the usual pre- and post-procedure work. The E/M note must support the code level independently from the procedure documentation. This is a frequently misapplied scenario modifier -25 without supporting documentation is an audit red flag.
