Every Undercoded E/M Visit Is Money Your Practice Will Never Get Back

It happens in dermatology practices across the country, every single day. A new patient presents with psoriasis, two skin lesions requiring evaluation, and a suspicious mole that leads to a biopsy decision. The dermatologist documents a thorough encounter, spends 50 minutes with the patient, reviews prior records, and makes a clinically complex decision. Then the visit gets coded 99203 a low-complexity code because no one confirmed what the documentation actually supported.

The result? The practice collects $50–$80 less than it earned on that one visit. Multiply that by 15 new patients a week, 50 weeks a year, and the practice has left $37,500–$60,000 on the table annually from undercoding alone, without a single denied claim.

In 2026, with MDM-based coding now fully embedded in payer expectations and AMA E/M guidelines enforced at the claim level, understanding exactly how to select, document, and defend CPT codes 99202 through 99205 is one of the most direct revenue optimization levers available to any dermatology practice. This guide gives your team everything it needs to get it right.

💡  Did You Know?

The average dermatology practice undercodes E/M visits by 1–2 levels on approximately 30–40% of new patient encounters a systematic revenue gap that adds up to six figures annually for most practices.

Since the 2021 AMA E/M coding overhaul, Medical Decision Making (MDM) and total time are the only two pathways for E/M code selection. History and physical exam components no longer determine code level yet many practices still code as if they do.

RAC auditors and commercial payers are actively targeting E/M overcoding AND undercoding both create liability. The goal is precision: coding to exactly what the documentation supports, every time.

What Are CPT Codes 99202–99205 — And How Do They Work in 2026?

CPT codes 99202 through 99205 are the new patient office/outpatient Evaluation and Management (E/M) codes — used to bill for a patient's first visit to a practice (or a visit occurring more than three years after the last encounter with any provider in the same specialty group).

As of the 2021 AMA E/M revision still fully in effect in 2026 these codes are selected based on one of two pathways: Medical Decision Making (MDM) complexity, or Total Time spent by the provider on the date of service. History and physical exam components no longer determine code level. They are documented as medically appropriate, but they don't drive code selection.

For dermatology, this shift is significant. MDM-based coding now rewards clinical complexity rather than documentation volume — which means a provider who makes a genuinely complex clinical decision can support a 99204 or 99205 without needing an exhaustive multi-system exam to justify it. The challenge is that providers must understand MDM components well enough to document them accurately.

📊 CPT 99202–99205: Complete Comparison Table for Dermatology Billing

Here is the full reference guide for all four new patient E/M codes with dermatology-specific use cases and current reimbursement ranges:

📈  Revenue Impact Insight

A dermatology practice seeing 20 new patients per week that systematically codes all moderately complex new patient encounters at 99203 instead of 99204 is leaving $55 per visit × 20 visits × 50 weeks = $55,000 annually in legitimate, earned reimbursement uncollected. With zero additional patients. Zero additional clinical work. Just accurate code selection.

⏱ Time-Based vs. MDM-Based Coding — Which Pathway Should Dermatology Use?

One of the most common sources of confusion since the 2021 AMA revisions is when to use time-based coding versus MDM-based coding. The answer is straightforward: use whichever pathway the documentation best supports and whichever results in the most accurate and defensible code level.

For most dermatology encounters, MDM is the more defensible and often the more advantageous pathway. Dermatology visits naturally involve multiple problems, data review (lab results, pathology, imaging), and treatment risk decisions (Rx management, biopsies, systemic agents) all of which contribute directly to MDM level.

Time-based coding works best when the provider spends additional time on counseling, care coordination, or reviewing extensive records and that time is precisely documented in the chart note with a total encounter time statement.

🧠 MDM Simplified for Dermatology Providers — The Three-Element Framework

Medical Decision Making is assessed across three equally weighted elements. The final MDM level is determined by the overall complexity profile — not by the highest-scoring single element. Understanding each element in clinical dermatology terms is what allows accurate, defensible code selection:

MDM Level	Problems Addressed	Data Reviewed & Analyzed	Risk Level
Straightforward (99202)	1 self-limited/minor problem	Minimal or no data reviewed	Minimal risk — no Rx drugs, no procedures
Low Complexity (99203)	2+ self-limited problems OR 1 stable chronic condition	Limited data — 1–2 test results, prior records reviewed	Low risk — OTC Rx, minor procedures considered
Moderate Complexity (99204)	1+ chronic illness with mild exacerbation OR 2+ stable chronic conditions	Moderate data — independent interpretation of tests, discussion with other providers	Moderate risk — Rx drug management, minor surgical procedure ordered
High Complexity (99205)	1+ chronic illness with severe exacerbation OR 1 acute illness posing threat to life	Extensive data — independent interpretation of multiple tests, independent historian	High risk — drug therapy requiring intensive monitoring or major surgery decision

The critical takeaway: MDM level is determined by the complexity of the problems, the quantity and type of data analyzed, and the level of risk involved in management decisions. Dermatology providers regularly meet moderate and high MDM thresholds — they just don't always document them clearly enough to support those codes at the billing level.

🩺 Dermatology-Specific E/M Coding Scenarios — Code Selection in Practice

Scenario 1: New Patient — Mild Acne (CPT 99202 or 99203)

A 19-year-old new patient presents with mild comedonal acne. No prior treatment. No systemic concerns. The dermatologist reviews the patient's skin, discusses topical options, and prescribes a retinoid. This encounter meets Straightforward or Low MDM: single self-limited problem, minimal data, low-risk prescription. Code 99202 (if visit is brief and efficient) or 99203 (if time or additional complexity pushes to low MDM).

Scenario 2: New Patient — Suspicious Pigmented Lesion with Biopsy Decision (CPT 99204)

A 44-year-old new patient is referred for evaluation of a changing mole on the back. The dermatologist reviews previous dermatology records, performs dermoscopy, documents the lesion's features against ABCDE criteria, and decides to perform a punch biopsy with pathology review. This encounter meets Moderate MDM: one problem with significant diagnostic uncertainty, data review including prior records and independent interpretation of dermoscopy findings, moderate risk due to biopsy procedure and Rx decision. Code 99204 — not 99203.

Scenario 3: New Patient — Complex Psoriasis with Systemic Therapy Decision (CPT 99205)

A 52-year-old new patient with plaque psoriasis affecting 40% of BSA, psoriatic arthritis, and hypertension presents for initial evaluation. The dermatologist reviews records from the rheumatologist, evaluates cardiovascular risk for biologic therapy, discusses treatment options including methotrexate versus a biologic agent, and consults with the primary care provider about contraindications. This encounter meets High MDM: chronic illness with severe manifestation, extensive data review including independent evaluation of multiple records and discussion with other providers, high risk due to drug therapy requiring intensive monitoring. Code 99205 — fully justified.

Scenario 4: New Patient — Annual Skin Check with Multiple Findings (CPT 99203–99204)

A 61-year-old new patient requests a full skin examination. The dermatologist identifies actinic keratoses on the scalp, a suspicious seborrheic keratosis on the trunk, and mild rosacea. Three clinical problems are addressed, treatment recommendations are made for each, and a topical is prescribed. Code selection depends on MDM: if each problem is stable and data review is minimal, 99203 may apply. If the AK evaluation involved reviewing prior pathology or making a treatment decision for multiple conditions simultaneously, 99204 is more appropriate.

🧾 Documentation Requirements for CPT 99202–99205 — 2026 Compliance Checklist

Since history and physical exam no longer drive code level, the documentation focus has shifted entirely to MDM and time. Here is the complete documentation standard your practice must meet for defensible new patient E/M billing:

🧾  E/M Documentation Compliance Checklist — MedCloudMD 2026 Standard

✔  Problems Addressed Documented: Every condition assessed during the encounter listed with diagnostic status (new, established, worsening, stable). Number and complexity of problems drives MDM Problem element.

✔  Data Elements Explicitly Documented: If reviewing prior records, document what was reviewed and your clinical impression. If ordering tests, document reason. If consulting another provider, document the discussion and its impact on your clinical decision.

✔  Risk Level Documented: State the management decisions made — specifically prescription medications, procedures ordered, referrals made, or monitoring required. Risk is assessed based on the management decision with the highest risk level.

✔  History Documented 'As Medically Appropriate': Chief complaint, relevant HPI, ROS, and PFSH documented to the extent clinically relevant. Not required to be comprehensive for code selection — but completeness supports medical necessity.

✔  Physical Exam Documented 'As Medically Appropriate': Exam findings documented based on clinical need — not a required element count. Focus on findings that directly support the MDM complexity being claimed.

✔  Total Time Documented (If Time-Based): State total provider time on date of service in minutes — including both face-to-face and non-face-to-face time (chart review, documentation, care coordination). Must be performed on the same calendar date.

✔  New Patient Status Confirmed: Verify patient has not been seen by any provider of the same specialty within the same group practice in the past three years. Billing a new patient E/M incorrectly triggers both denial and compliance exposure.

✔  MDM Level Supported by All Three Elements: Before selecting the code, confirm that the Problems, Data, and Risk elements collectively support the MDM level being billed. All three must independently support — or the lower element caps the code.

✔  Diagnosis Codes Match Clinical Narrative: Every ICD-10 code submitted must be directly traceable to a condition documented in the clinical note. Diagnosis-note mismatches are among the top triggers for automated denials.

✔  Provider Signature and Date: All documentation signed and dated by the treating provider on the date of service. Co-signed or undated notes create compliance vulnerabilities in any payer audit.

💰 Revenue Impact of Accurate E/M Coding — Undercoding vs. Correct Code Selection

Here is the direct revenue comparison between systematic undercoding and accurate E/M code selection across the most common new patient dermatology scenarios. These figures use conservative Medicare reimbursement estimates:

Clinical Scenario	Code Used (Undercoded)	Undercoded Reimbursement	Correct Code	Correct Reimbursement	Revenue Gained
New patient acne evaluation	99202 (undercoded)	$95	99203	$140	+$45 per visit
Psoriasis initial consultation	99203 (undercoded)	$140	99204	$195	+$55 per visit
Suspicious mole + biopsy decision	99203 (undercoded)	$140	99204	$195	+$55 per visit
Complex multi-diagnosis new patient	99204 (undercoded)	$195	99205	$240	+$45 per visit
Melanoma workup + systemic review	99204 (undercoded)	$195	99205	$240	+$45 per visit

📈  Annual Revenue Projection — The Real Cost of Systematic Undercoding

A dermatology practice seeing 800 new patients per year that undercodes 35% of visits by one code level loses an average of $50 per affected visit × 280 visits = $14,000 annually at minimum. When two-level undercoding occurs on complex visits coding 99203 instead of 99205 the per-visit loss reaches $100–$145, pushing total annual revenue leakage to $28,000–$40,000+. This is unrecovered revenue from clinical work already performed.

🚫 Common E/M Billing Mistakes That Cost Dermatology Practices Revenue

🚫  The Coding Errors Your Practice Cannot Afford to Keep Making

Defaulting to 99203 for All New Patient Visits: Using 99203 as a 'safe' default code for every new patient encounter is one of the most costly systematic billing errors in dermatology. The majority of new patient visits in a dermatology practice involving multiple diagnoses, data review, and prescription decisions — meet 99204 criteria or higher.

Coding by Time Without Documenting Time: Selecting a higher-level code based on time without explicitly stating total provider time in the chart note creates an indefensible claim. Time-based coding without documented total time is not a valid basis for code selection in any payer audit.

Using History and Exam Elements to Select MDM Level: Since 2021, the number of systems reviewed or exam elements documented no longer determines E/M code level. Providers who still code this way are systematically miscoding — either under or over — based on outdated criteria.

Failing to Document the Data Element of MDM: Many providers document the problem and the management decision clearly but omit documentation of what data they reviewed — prior records, test results, independent interpretations. Without data element documentation, the MDM level is capped lower than the encounter may support.

Billing 99205 Without High-Complexity MDM Support: 99205 requires high complexity MDM — including a problem with severe exacerbation, extensive data review, and high-risk management decisions. Applying it to moderate-complexity encounters is a red flag audit trigger, especially for Medicare.

Ignoring New Patient vs. Established Patient Status: Billing a new patient code for an established patient — particularly in group practices where the patient has seen another provider in the same specialty — is a compliance violation that results in both denial and potential overpayment recoupment.

Not Reviewing MDM Documentation Before Submitting Claims: Claims submitted without a pre-submission review of MDM element support consistently generate higher denial rates and underpayment rates than claims with a structured coding review process.

✅ Pro Tips to Maximize Dermatology E/M Revenue in 2026

✅  Expert Strategies From the MedCloudMD E/M Coding Team

Train Providers to Document the MDM Story — Not Just the Clinical Facts: The clinical note should tell the story of complexity. 'Reviewed prior dermatology records from 2023, identified previous biopsy results, and independently reassessed pathology findings in the context of current presentation' is far more defensible than 'reviewed prior records'.

Create a Dermatology-Specific MDM Quick Reference Card: Post a laminated MDM reference card in every exam room showing the three MDM elements and what meets each level in a dermatology clinical context. When providers can see the criteria while they're documenting, code accuracy improves immediately.

Use Time-Based Coding Strategically for Complex Counseling Visits: When a new patient consultation involves extensive counseling about treatment options, risks, and lifestyle factors and the provider spends 55+ minutes on the encounter — time-based coding at 99205 may be more supportable than MDM-based coding. Document total time explicitly.

Bill 99204 Confidently for Multi-Diagnosis New Patient Visits: Any new patient encounter involving two or more chronic conditions, a prescription decision, or a procedure evaluation almost always meets Moderate MDM. Coding it at 99203 is systematic undercoding. Build a workflow that prompts providers to identify when 99204 applies.

Conduct Quarterly E/M Coding Audits — Even With Outsourced Billing: Pull a random sample of 25 new patient encounters each quarter and evaluate whether the documented MDM matches the code selected. Systematic drift in either direction surfaces quickly and is correctable before payers identify it.

Align Diagnosis Coding With E/M Level: A 99205 claim supported by a single ICD-10 code for a minor skin condition raises automatic audit flags. The diagnoses submitted must reflect the complexity claimed in the E/M code — multiple conditions, systemic considerations, or high-risk diagnoses.

⚠️ 2026 Compliance & Audit Risks — What Every Dermatology Practice Must Know

⚠️  Compliance Alert — E/M Audit Activity Is Increasing in 2026

Medicare RAC Auditors Are Actively Targeting E/M Coding Patterns: Recovery Audit Contractors review practices whose E/M code distribution differs significantly from specialty benchmarks. A dermatology practice billing 99205 on 60% of new patient visits will be flagged — regardless of whether individual claims are supported.

OIG Work Plan Includes E/M Upcoding as a Recurring Target: The Office of Inspector General consistently identifies E/M upcoding in high-procedure specialties as a billing integrity risk. Practices with outlier coding profiles face pre-payment and post-payment audits.

Commercial Payers Are Implementing Algorithmic Claim Review: Major commercial insurers now use AI-driven claim review systems that flag E/M codes inconsistent with the submitted diagnoses, provider specialty, and historical coding patterns. These systems catch both overcoding and undercoding.

Undercoding Is Also a Compliance Risk — Not Just a Revenue Problem: Systematically undercoding to avoid scrutiny is not a safe strategy. It creates an inaccurate financial record of the practice's services and, in certain contexts, can be characterized as misrepresentation of services rendered.

Documentation Must Match the Code — Not the Other Way Around: Selecting the code first and then writing documentation to support it is a compliance violation. Documentation must reflect the actual clinical encounter, and code selection must follow from that documentation.

Why Dermatology Practices Are Outsourcing E/M Billing to Specialist Teams

E/M coding for new patient encounters is not a mechanical process it requires clinical coding judgment, MDM analysis, documentation review, and continuous payer policy awareness that most in-house billing teams are not equipped to apply consistently across high-volume dermatology practices.

The Staff Error Problem Is Systematic, Not Individual

When in-house billing staff apply the same default code 99203 to every new patient encounter, it's rarely because they're making a careless mistake. It's because they haven't been trained on MDM-based coding analysis and don't have the clinical context to identify when a 99204 or 99205 is appropriate. This is a structural problem that training sessions don't reliably fix and one that outsourced specialist coders solve permanently.

The Revenue Leakage Compounds Silently

E/M undercoding doesn't generate denial notices. There's no system alert when a 99204 is coded as a 99203. The revenue simply never arrives and the practice never knows it was entitled to more. Only a structured coding audit reveals the pattern and only a specialist billing team prevents it from recurring.
