CPT code 99205: definition, documentation, MDM, and 2026 Medicare rates

Key Takeaways

CPT code 99205 is the highest-level new patient office or outpatient E/M code, requiring high complexity MDM or 60-74 minutes of total time on the date of encounter.

Code selection uses either the MDM pathway or the time pathway – not both; high MDM requires meeting 2 of 3 AMA elements at the high level.

Modifier 25 is required when billing 99205 on the same day as a procedure; upcoding 99205 is a known OIG and RAC audit target.

Practice management software like Pabau, with claims management and an AI medical scribe, helps practices document, code, and submit E/M visits accurately to reduce denials.

CPT code 99205 is the highest-level evaluation and management (E/M) code for a new patient office or outpatient visit. Also searched as procedure code 99205, it applies when the encounter involves high-complexity medical decision-making or 60 to 74 minutes of total time on the date of service. This guide covers the definition, the MDM and time documentation rules, modifier and reimbursement considerations, and how 99205 differs from 99204.

CPT code 99205: definition and official description

Most new patient visits never reach this level. Claims management software that logs denial patterns across thousands of encounters consistently flags 99205 as one of the most commonly miscoded new patient E/M codes – billed too often for encounters that don’t meet the threshold, and sometimes under-billed when they do.

CPT code 99205 is the highest-level evaluation and management code for new patient office or other outpatient visits, as defined by the American Medical Association’s CPT code set.

The official descriptor reads: Office or other outpatient visit for the evaluation and management of a new patient, which requires a medically appropriate history and/or examination and high level of medical decision making. When using time for code selection, 60-74 minutes of total time is spent on the date of the encounter.

This article covers the documentation requirements, MDM criteria, time rules, 2026 Medicare reimbursement rates, applicable modifiers, and common denial reasons for CPT code 99205.

New patient E/M code series: 99202 through 99205

CPT code 99205 sits at the top of the new patient office visit series. Understanding where it lands in the full range helps coders choose the right level and avoid upcoding exposure.

CPT code 99201 was deleted effective January 1, 2021, when the AMA overhauled the E/M guidelines and the new patient series became 99202-99205. Before 2021, all three key components (history, examination, and MDM) were required for new patient codes. That requirement no longer applies. Code selection now rests on MDM complexity or total time on the date of encounter – whichever the provider chooses.

One important distinction: 99205 is classified as a new patient code. A patient is “new” if they have not received professional services from the billing provider (or any provider of the same specialty in the same group practice) within the past three years. Established patients use codes 99211-99215.

Documentation requirements and MDM criteria

Every 99205 claim needs documentation that supports the selected pathway – MDM or time. Incomplete or vague notes are the most common reason for downcoding on audit.

MDM pathway: high complexity

High complexity MDM requires meeting at least 2 of the following 3 AMA elements at the high level:

• Problems addressed: One or more chronic illnesses with severe exacerbation, progression, or side effects of treatment; or a new problem with uncertain prognosis; or an acute or chronic illness that poses a threat to life or bodily function.
• Amount and/or complexity of data: Must include a combination that meets the “extensive” threshold – typically involving independent interpretation of tests, independent historian documentation, or discussion with external providers.
• Risk of complications and/or morbidity or mortality: Drug therapy requiring intensive monitoring for toxicity, decision for hospitalization, or decision to de-escalate care due to poor prognosis.

The note must reflect each element clearly. Phrases like “patient has complex medical history” don’t cut it. Document the specific conditions addressed, the data reviewed, and the risk-based decision made during the encounter. Digital intake forms that capture structured history before the visit give providers a starting point – but the clinical note itself must carry the MDM documentation.

Time pathway: 60-74 minutes

The 99205 time requirement is 60 to 74 minutes of total time on the date of the encounter. Since 2021, “time” for E/M purposes means total provider time – not just face-to-face time. This includes reviewing records, ordering tests, coordinating care with other providers, and preparing notes. Time spent by clinical staff members who are not the billing provider does not count.

The note must document the total time spent and briefly describe the activities performed. A simple statement such as “Total time today including pre-visit review, examination, and care coordination: 65 minutes” satisfies the requirement when the activities are also summarized.

For encounters exceeding 74 minutes, prolonged services can be added to CPT code 99205: bill HCPCS add-on G2212 for Medicare, or CPT +99417 for commercial and other AMA-aligned payers. Verify payer-specific acceptance before billing.

Practices managing high-volume new patient schedules benefit from consistent documentation templates, such as a standard admissions assessment and intake evaluation template. Reviewing your HIPAA compliance checklist for primary care alongside your documentation standards helps ensure notes meet both privacy and billing requirements.

Time-based billing and modifier rules

Two modifier situations arise frequently when billing CPT code 99205, and both carry audit risk.

Modifier 25: same-day procedure

When a provider performs a procedure on the same date as a new patient E/M visit, Modifier 25 must be appended to the E/M code. It signals that the E/M service was a separately identifiable evaluation – not just the pre-service workup for the procedure itself.

The documentation burden here is real. The note must demonstrate that the E/M service addressed a problem or condition that was distinct from the procedure, or that the decision to perform the procedure was itself based on findings from the E/M.

The Office of Inspector General (OIG) has flagged Modifier 25 as a high-risk billing pattern for years. Claims that bill an E/M with a procedure on every date of service attract RAC scrutiny.

99205 vs 99204: choosing the right level

The practical question for most coders is whether a given new patient encounter supports 99205 or the adjacent 99204. The MDM distinction is moderate versus high complexity.

In behavioral health and psychiatry, CPT code 99205 is commonly appropriate for initial evaluations involving multiple psychiatric comorbidities, active suicidal ideation, or severe substance use disorders with medical complications. Practices serving these populations should review their psychiatry EMR software capabilities for documentation support at these complexity levels.

Primary care and family practices see similar complexity when new patients present with several unmanaged chronic conditions. Reviewing how GP clinic software handles time tracking and problem lists helps support the same MDM documentation standard.

CPT code 99205 reimbursement rates and RVU values

Medicare reimbursement for CPT code 99205 is calculated using the Resource-Based Relative Value Scale (RBRVS). The 2026 national non-facility rate is approximately $236.81, but this figure varies by geographic locality. Always verify the current rate using the CMS Physician Fee Schedule lookup tool for your specific practice location.

RVU breakdown

The 99205 RVU breakdown has three components. For CPT code 99205, the approximate 2026 values are:

These are approximate 2026 values. Verify the exact current figures against the CMS 2026 Medicare Physician Fee Schedule (MPFS) RVU file using the CMS Physician Fee Schedule lookup tool before relying on them for billing. RVU values shift annually with the MPFS final rule, and the total RVU above is what supports the payment figure quoted earlier in this guide.

Nurse practitioners and physician assistants

NPs and PAs can bill CPT code 99205 independently under Medicare at 85% of the physician fee schedule rate. Under incident-to billing, the rate is 100% – but incident-to rules require the supervising physician to have an established treatment plan and be present in the office suite during the visit.

New patients almost always require the NP or PA to bill in their own name, since incident-to applies only when treating an established condition. Always confirm payer-specific rules before selecting the billing path.

State Medicaid programs and commercial insurers set their own rates independently of Medicare. Reimbursement can vary significantly. For practices evaluating software that tracks payer-specific rates, resources like finding the best EHR for private practice cover key considerations for practices billing multiple payer types.

Common denial reasons and how to avoid them

CPT code 99205 is a known audit target. It’s the highest-level new patient code, which makes it the first place payers look when reviewing outlier billing patterns. Practices with high 99205 utilization relative to their specialty benchmark attract RAC and payer review.

• Insufficient MDM documentation: The note lists diagnoses without demonstrating the complexity of decision-making. Fix: document specific conditions addressed, data sources reviewed, and risk-based decisions in distinct sections.
• Vague or missing time documentation: The note says “complex visit” without stating total time or activities performed. Fix: record total time explicitly and summarize pre/post-visit work in addition to the examination itself.
• Modifier 25 without separate E/M documentation: The E/M note doesn’t stand independently from the procedure note. Fix: document the E/M findings and decision-making in a separate section of the record.
• New patient status error: The patient was seen within the last three years by a same-specialty provider in the same group. Fix: verify new patient status at intake, before billing.
• Upcoding pattern: A provider bills 99205 for more than 20-25% of new patient visits, which is above typical specialty benchmarks. Fix: audit your E/M level distribution quarterly against AAPC coding benchmarks for your specialty.

Practices running direct primary care software sometimes bypass insurance billing entirely, but for those who bill Medicare or commercial plans, periodic internal audits of CPT code 99205 claims are standard risk management. Pulling a sample of 99205 claims quarterly and checking the notes against MDM or time criteria takes less than an hour and identifies pattern problems before a payer audit does.

Practices can also benefit from reviewing how other CPT code guides, such as CPT code 01470 and CPT code 00922, handle documentation workflows – the principles for capturing clinical complexity apply across specialties.

Telehealth and software billing considerations

CPT code 99205 can be billed for telehealth encounters under CMS’s ongoing telehealth flexibilities. The same MDM or time criteria apply. For time-based billing via telehealth, total time includes the video visit itself plus pre- and post-encounter work completed on the same date.

Post-PHE telehealth rules continue to evolve, so confirm the current Place of Service (POS) code requirements with your Medicare Administrative Contractor (MAC) before billing 99205 for a telehealth new patient visit. POS 02 (telehealth, patient not in their home) and POS 10 (telehealth, patient in their home) carry different reimbursement implications.

Modifier 95 is typically appended to the E/M code for synchronous audio-video telehealth, in addition to the correct POS code.

On the software side, practices using AI medical scribe tools during telehealth visits can capture structured notes in real time, which supports both time documentation and MDM evidence. The note generated during the visit should be reviewed and attested by the billing provider before the claim goes out.

For practices building out their first visit workflows, reviewing what practice management software needs to handle across billing, scheduling, and documentation helps connect the dots between clinical and operational requirements. The 99205 claim is only as strong as the workflow supporting it.

Conclusion

CPT code 99205 is the highest-stakes new patient E/M code in the 99202-99205 series. Getting it right means meeting the MDM or time threshold, documenting it clearly, and applying Modifier 25 correctly when procedures appear on the same date.
