Navigating the world of medical billing and coding can feel like learning a new language. For healthcare providers, medical coders, and billers, understanding Evaluation and Management (E/M) codes is a fundamental part of the job. These codes are the backbone of how you get paid for patient visits. Among them, the code for a new patient office visit is one of the most frequently used.
This guide focuses specifically on CPT code 99202. It provides a comprehensive overview of what this code means, when to use it, and how the rules have changed in recent years. This information is crucial for accurate billing and maintaining a healthy revenue cycle.
What is CPT Code 99202?
CPT code 99202 represents an office or other outpatient visit for the evaluation and management of a new patient. The “new patient” designation is critical. It means the patient has not received any professional services from the physician or another physician of the same specialty in the same group practice within the past three years.
This code is used for visits that require a medically appropriate history and examination. It signifies a low level of medical decision making (MDM) is involved. This is the second-lowest level for new patient visits, sitting just above CPT code 99201. However, following major changes in 2021, 99201 was deleted, making 99202 the entry-level code for new patient E/M services.
The 2021 changes, implemented by the American Medical Association (AMA), revolutionized how E/M codes are selected. The focus shifted from a complex point system based on history, exam, and MDM to a simplified approach. Now, for codes 99202 through 99205, you can select the level of service based solely on the level of medical decision making or total time spent on the date of the encounter.
This change was designed to reduce the administrative burden on physicians, allowing them to spend more time on patient care and less on cumbersome documentation. The history and exam components are still performed, but they are only required to be “medically appropriate.” They are no longer used as a scoring tool to determine the correct code level.
Key Characteristics of 99202
- Patient Status: New patient.
- Setting: Office or other outpatient setting.
- Medical Decision Making: Straightforward.
- Total Time: 15-29 minutes.
Understanding these key characteristics is the first step in ensuring you are coding accurately. Let’s break down each of these components in more detail.
When to Use CPT Code 99202
Determining when to use 99202 requires a clear understanding of two main factors: the patient’s status as new and the level of medical decision making or time involved.
Defining a “New Patient”
A new patient is someone who has not received professional services from a physician or qualified health care professional (QHP) of the exact same specialty and subspecialty within the same group practice within the last three years. For example, if a patient sees a general cardiologist in a practice, they are a new patient if they are then referred to an interventional cardiologist in the same group, as these are considered different subspecialties.
The key elements to consider are:
- The professional service provided.
- The specialty of the provider.
- The group practice.
- The three-year time frame.
If all these conditions align to confirm the patient is “new,” then you can use a new patient E/M code (99202-99205). If the patient has been seen before, you must use an established patient code (99211-99215).
Understanding Medical Decision Making (MDM)
For E/M coding, MDM is the driving factor in code selection. For 99202, the MDM level is Straightforward. This is the lowest level of MDM. It typically involves:
- Number and Complexity of Problems Addressed: 1 self-limited or minor problem.
- Amount and/or Complexity of Data to be Reviewed and Analyzed: Minimal or none.
- Risk of Complications and/or Morbidity or Mortality: Minimal risk.
Here is a table that breaks down the MDM components for a Straightforward level of MDM:
| MDM Component | Straightforward MDM (for 99202) |
|---|---|
| Problems Addressed | 1 self-limited or minor problem (e.g., a common cold, insect bite, or simple rash). |
| Data Reviewed | Minimal or no data reviewed (e.g., reviewing a simple, recent lab test or vital signs). |
| Risk of Complications | Minimal risk of morbidity or mortality from additional testing or treatment. |
To use 99202, the MDM for the encounter must meet the criteria in at least two of the three categories above. This ensures that the encounter is relatively straightforward from a clinical perspective.
Understanding Total Time
One of the most significant shifts in 2021 was the redefinition of “time.” For E/M code selection, time is defined as the total time spent on the date of the encounter. This includes both face-to-face and non-face-to-face time spent by the physician or QHP.
The total time for CPT code 99202 is 15-29 minutes.
Eligible activities that can be counted toward this total time include:
- Preparing to see the patient (e.g., reviewing the chart).
- Obtaining and/or reviewing a separately obtained history.
- Performing a medically appropriate examination.
- Counseling and educating the patient, family, or caregiver.
- Ordering medications, tests, or procedures.
- Referring and communicating with other health care professionals (when not separately reported).
- Documenting clinical information in the electronic health record (EHR).
- Independently interpreting results (not separately reported) and communicating results to the patient, family, or caregiver.
- Care coordination (not separately reported).
This broader definition of time allows physicians to accurately reflect the true amount of work involved in a patient encounter, even when a large portion of it is not spent directly in front of the patient.
CPT Code 99202: Documentation Requirements
Although the documentation requirements have been simplified, they are still crucial for compliance and successful billing. The medical record must support the level of service billed. For 99202, the documentation must clearly show that the MDM was straightforward or that the visit’s total time fell within the 15-29 minute range.
The AMA’s 2021 guidelines emphasize that the medical record should be “medically appropriate.” This means you should document a clinically relevant history and physical exam that tells the story of the patient’s visit. You no longer need to hit a specific number of elements in the history or exam.
When documenting time, it is a best practice to explicitly state the total time spent on the visit in the encounter note. For example, a simple sentence like, “I spent 20 minutes on this patient encounter, including reviewing records, the examination, and documenting,” is sufficient. This proactive approach removes any ambiguity during an audit.
How the 2021 E/M Changes Impacted 99202
The overhaul of E/M coding in 2021 was a landmark event. Before this, coders and physicians had to navigate a complex grid of history (HPI, ROS, PFSH), examination (organ systems, body areas), and MDM. This often led to “note bloat,” where patient charts were filled with irrelevant or copied-and-pasted information just to justify a higher level of billing.
The new guidelines for 99202 and other office visit codes were designed to:
- Reduce Administrative Burden: By allowing the selection of the code to be based on MDM or time alone, the amount of time spent worrying about documentation checkboxes decreased significantly.
- Improve Patient Care: With less focus on meeting documentation quotas, physicians can focus more on the patient, improving the quality of the visit.
- Simplify Coding: The guidelines are now cleaner and more intuitive. If the medical decision making is straightforward, you bill 99202. If you spent 20 minutes of total time, you bill 99202.
This change meant that the older requirement for a specific level of history and exam was no longer a determining factor for code selection. The responsibility shifted to accurately documenting the complexity of the medical decision making or the total time spent.
Comparing CPT Code 99202 to Other E/M Codes
Understanding how 99202 fits into the broader landscape of E/M codes is essential for accurate billing. Here is a comparison with other common office visit codes.
Comparison of New Patient and Established Patient Codes
The main difference is the patient’s status. This table compares the new patient codes (99202-99205) with their established patient counterparts (99212-99215) based on the 2021 guidelines.
| Feature | New Patient Codes (99202-99205) | Established Patient Codes (99212-99215) |
|---|---|---|
| Patient Status | New to the provider/specialty/group in the last 3 years. | Has been seen by the provider/specialty/group in the last 3 years. |
| Code Selection Basis | Medical Decision Making (MDM) or Total Time. | Medical Decision Making (MDM) or Total Time. |
| MDM Levels | Straightforward, Low, Moderate, High. | Straightforward, Low, Moderate, High. |
| Key Rule | Must meet MDM criteria in 2 of 3 elements or meet time threshold. | Must meet MDM criteria in 2 of 3 elements or meet time threshold. |
The complexity of MDM is similar, but the total time thresholds are slightly lower for established patients, as the work of gathering initial history is not usually repeated.
CPT Code 99202 vs. 99212
These two codes represent a similar, low level of medical decision making but apply to different patient types.
| Feature | CPT Code 99202 | CPT Code 99212 |
|---|---|---|
| Patient Type | New Patient | Established Patient |
| Level of MDM | Straightforward | Straightforward |
| Total Time | 15-29 minutes | 10-19 minutes |
| Typical Scenario | A new patient presents with a simple, minor complaint like a rash or a common cold. | An established patient calls in for a quick prescription refill or a very minor issue. |
The primary distinction is the patient’s status. As a rule, new patient visits require more work to review past medical, family, and social history, which is why the time requirement is slightly higher.
Common Scenarios for Using CPT Code 99202
To make this more concrete, let’s look at some realistic examples where 99202 would be the correct code to bill.
Scenario 1: The Simple Rash
A 30-year-old new patient comes in for a mild, localized rash on their arm that appeared two days ago. They have no other symptoms. You review their past medical history, perform a focused examination of the skin, determine it is contact dermatitis, and recommend an over-the-counter hydrocortisone cream. The MDM is straightforward, as it involves one minor problem and minimal risk. You spend 16 minutes on the encounter. Code 99202 is appropriate.
Scenario 2: A Minor Sports Injury
A 22-year-old new patient presents with a mild ankle sprain from playing basketball. The pain is manageable, and they can walk with a slight limp. You perform a problem-focused exam, determine there are no fractures by following the Ottawa Ankle Rules, and advise rest, ice, compression, and elevation (RICE). The medical decision making is straightforward. The total visit time is 18 minutes. Code 99202 is appropriate.
Scenario 3: A Routine Question
A new patient comes in with a single, simple question about a minor issue, like a small wart on their hand. You examine the wart, explain the treatment options (e.g., over-the-counter salicylic acid or cryotherapy), and answer their questions. The problem is minor, the data reviewed is minimal, and the risk is low. The total time spent is 15 minutes. Code 99202 is appropriate.
Common Mistakes to Avoid When Billing 99202
Even with simplified guidelines, errors can occur. Here are some common pitfalls to watch out for.
- Confusing New and Established Patients: This is the most frequent mistake. Always verify the patient’s status with your practice’s records before selecting the code. A patient seen by a colleague in the same specialty is an established patient, even if you have never personally seen them.
- Undercoding: Some providers, out of caution or confusion, might bill 99202 for a visit that warranted a higher code like 99203 or 99204. If the MDM or time supports a higher level, you should bill that higher level. Undercoding means you are not getting reimbursed for the full work you performed.
- Overcoding: This is the opposite problem. Billing 99202 when the visit only involved a quick question or a service that doesn’t meet the criteria could be viewed as upcoding if the MDM or time was not there. While 99202 is the lowest level now, it still requires 15 minutes of time or straightforward MDM.
- Misinterpreting “Time”: Some providers still think of time as only face-to-face time. The total time includes pre-visit review, documentation, and post-visit coordination. Be sure to count all time spent on the date of service.
- Failing to Document Time: If you are using time to select the code, you must document it. A claim without documentation of total time is vulnerable to a downcode or denial during an audit.
The Impact of 99202 on Your Practice
Accurate use of 99202 directly impacts your practice’s financial health. For many primary care and specialty practices, new patient visits are the lifeblood of growth. Correct coding ensures you are appropriately reimbursed for the time and effort spent managing these new patients.
The 2021 changes were designed to make E/M coding more intuitive. However, they also require a shift in mindset. Providers must be diligent in understanding what constitutes straightforward MDM and be meticulous in documenting their total time. Proper training for all staff involved in the revenue cycle—from front desk staff who check patient status to providers who document the visit to coders who submit the claim—is essential for success.
It is also important to understand that 99202 is not a “filler” code. It represents a specific, measurable amount of work and clinical judgment. Treating it as a default for all simple new patient visits is appropriate, but you must ensure the documentation supports it.
Medicare Reimbursement for 99202
Reimbursement rates vary by geographical location. However, the 2024 Medicare Physician Fee Schedule provides a national average for the non-facility setting (like a private office).
| Code | Description | MDM Level | Total Time | 2024 Non-Facility Total RVU* (Approx.) |
|---|---|---|---|---|
| 99202 | New patient office visit | Straightforward | 15-29 min | ~1.83 |
| 99203 | New patient office visit | Low | 30-44 min | ~2.52 |
| 99204 | New patient office visit | Moderate | 45-59 min | ~3.81 |
| 99205 | New patient office visit | High | 60-74 min | ~4.94 |
*RVU = Relative Value Unit. The actual dollar amount is calculated by multiplying the total RVU by the Medicare conversion factor for the year. These figures are approximate and used for illustration.
How to Document for 99202: A Simple Checklist
To ensure you are billing 99202 correctly, follow this checklist for every new patient visit.
- Confirm Patient Status: Verify the patient is indeed “new” to your practice/specialty.
- Assess the Encounter: Determine the level of medical decision making (MDM).
- Is there one self-limited or minor problem?
- Is there minimal or no data to review?
- Is the risk of complications minimal?
- If you answered “yes” to at least two of these, the MDM is straightforward.
- Track Your Time: Record the total time spent on the visit for the day.
- Document Clearly: Write a concise note that includes a medically appropriate history and exam. Explicitly state: “Total time spent: XX minutes, with >XX minutes in counseling/coordination of care” (if applicable) or “Medical decision making was straightforward.”
- Select the Code: Based on MDM or time, choose 99202.
Conclusion
CPT code 99202 is a fundamental code for billing straightforward new patient office visits. The 2021 E/M coding updates simplified its use, basing it on medical decision making or total time. Understanding the rules for defining a new patient and documenting the encounter is essential for compliance and accurate reimbursement.
Frequently Asked Questions (FAQ)
Q: What does “new patient” mean for CPT code 99202?
A: A new patient is someone who has not received professional services from a physician or other qualified health care professional of the exact same specialty and subspecialty who belongs to the same group practice, within the past three years.
Q: How do I choose between using time or medical decision making (MDM) for 99202?
A: You can use whichever is most advantageous for that specific encounter. If the MDM is straightforward, you can use 99202. If you spent between 15 and 29 minutes of total time on the visit date, you can also use 99202. You do not need to meet both criteria.
Q: Can I still bill 99202 if a patient has insurance from a different company than a previous visit?
A: No, insurance type does not determine a patient’s status. If they have been seen by your group within the last three years for a professional service, they are considered an established patient, regardless of their insurance provider.
Q: What is included in “total time” for code 99202?
A: Total time includes all the time spent on the encounter on the date of the visit. This includes reviewing records before seeing the patient, the face-to-face time, documenting in the chart, ordering tests, and communicating with the patient or other providers about the care.
Q: What was deleted in the 2021 E/M changes related to 99202?
A: The major change was the deletion of CPT code 99201, which was previously the lowest-level new patient code. The requirements for a specified level of history and examination were also eliminated as key components for code selection. Now, only MDM or time dictates the code.
