Understanding CPT Codes 99202-99205: Descriptions, Billing Guides, and Differences
What Are CPT Codes 99202 to 99205?
The Current Procedural Terminology (CPT) code range for Office or Other Outpatient Services, specifically 99202-99205, is maintained by the American Medical Association.
These codes are used for new patient visits in office or outpatient settings and are part of the Evaluation and Management (E/M) coding system. These codes classify visits based on four main factors:
Time spent with the patient
History and examination were conducted during the visit
Medical decision-making complexity
Level of risk associated with the patient’s condition
Each code within this range corresponds to a different level of service, with CPT 99202 representing the simplest level and CPT 99205 being the most complex. Here’s a closer look at each code:
CPT 99202: Used for low-complexity new patient visits, requiring minimal history and examination.
CPT 99203: Represents a moderate complexity visit with a more detailed history and examination.
CPT 99204: Used for visits with moderate to high complexity, requiring a thorough history, examination, and medical decision-making.
CPT 99205: The highest level, involving extensive history, examination, and medical decision-making, often associated with high-risk conditions.

CPT Code 99202: Low Complexity, Quick Visit
Description:
CPT 99202 is used for new patients who need a basic evaluation for low complexity conditions. This code is ideal for visits that involve minimal time and straightforward medical decision-making.
Time Spent: 15-29 minutes
History and Examination: Medically appropriate, expanded problem-focused
Medical Decision Making: Straightforward (minimal risk)
Examples: This code is appropriate for patients with minor acute conditions such as a sore throat or simple health concerns like routine check-ups or minor injuries.
To correctly bill for CPT 99202, documentation should clearly support the straightforward nature of the visit, highlighting the time spent and the minimal complexity of the decision-making process.
CPT Code 99203: Low Complexity with Detailed Documentation
Description:
CPT 99203 is for new patient visits that require a bit more detail than 99202. In this case, the physician conducts a detailed history and examination and faces low complexity in medical decision-making.
Time Spent: 30-44 minutes
History and Examination: Detailed (includes review of systems, history of present illness, past medical, social, and family history)
Medical Decision Making: Low complexity
Examples: This code is often used for visits that require a deeper review, such as those involving well-controlled chronic conditions or concerns that need more investigation but don’t involve high risk. Conditions like mild asthma, controlled hypertension, or a routine mental health check-up might fall under this code.
The documentation should include a comprehensive history and detailed examination, along with low-risk decision-making.
CPT Code 99204: Moderate Complexity, Comprehensive Evaluation
Description:
For more complex cases, CPT 99204 is used. This code is ideal for new patients who need a comprehensive history, physical exam, and moderate complexity in decision-making.
Time Spent: 45-59 minutes
History and Examination: Comprehensive, covering multiple organ systems or extensive examination of a single organ system
Medical Decision Making: Moderate complexity
Examples: A visit for someone with uncontrolled hypertension or unexplained chronic fatigue would fit this code. These are cases that require more in-depth analysis, such as reviewing multiple lab results, coordinating care with specialists, or assessing the overall health status of the patient.
If counseling or coordinating care takes up more than 50% of the visit, it should be documented properly to ensure accurate billing.
CPT Code 99205: High Complexity, Extensive Workup
Description:
CPT 99205 is the highest-level E/M code for new patients. This code applies when the patient’s condition is of high complexity, requiring an extensive history, physical examination, and significant decision-making.
Time Spent: 60-74 minutes
History and Examination: Comprehensive (involves a full review of systems and detailed examination)
Medical Decision Making: High complexity (high risk)
Examples: This code is used for serious conditions that pose an immediate threat to life or physical function, such as a newly diagnosed cancer, severe mental health issues like depression with suicidal ideation, or a major health crisis requiring urgent care.
Due to the significant complexity and time required, this code typically commands a higher reimbursement rate and requires extensive documentation to justify the level of care provided.
Comparison Table for CPT Codes 99202-99205
| CPT Code | Time Spent | History & Exam | Medical Decision Making | Complexity Level | Examples |
|---|---|---|---|---|---|
| 99202 | 15-29 minutes | Medically appropriate, expanded problem-focused | Straightforward | Minimal | Minor illnesses (e.g., sore throat, routine check-ups) |
| 99203 | 30-44 minutes | Detailed (HPI, review of systems, social history) | Low complexity | Low risk | Chronic conditions (e.g., mild asthma, minor hypertension) |
| 99204 | 45-59 minutes | Comprehensive (multi-system review) | Moderate complexity | Moderate risk | Uncontrolled hypertension, significant fatigue |
| 99205 | 60-74 minutes | Comprehensive (full systems review) | High complexity | High risk | Serious conditions (e.g., cancer, depression with suicidal ideation) |
Conclusion
Understanding and correctly using CPT codes 99202 through 99205 is crucial for proper medical billing, accurate coding, and appropriate reimbursement.
By matching the complexity of the patient’s condition with the appropriate CPT code, healthcare providers ensure they are compensated fairly for their time and expertise.
Whether you’re dealing with minor illnesses, chronic conditions, or serious medical crises, these codes help streamline the billing process and reflect the true nature of the care provided.

Frequently Asked Questions (FAQs)
1. What’s the difference between CPT 99202 and CPT 99203?
CPT 99202 is for visits requiring less time (15-29 minutes) and simpler decision-making, while CPT 99203 involves a more detailed history and examination (30-44 minutes), with low complexity decision-making.
2. When should CPT 99204 be used?
CPT 99204 is appropriate for new patient visits that involve moderate complexity, such as cases requiring a detailed review of medical history and a more extensive examination (45-59 minutes).
3. What types of conditions are best suited for CPT 99205?
CPT 99205 should be used for high-risk conditions requiring an in-depth review and management, such as newly diagnosed cancer, serious mental health conditions, or any other complex health issue that poses a threat to life or function.
4. Does the time spent include only the doctor’s face-to-face time with the patient?
Yes, the time refers to the direct face-to-face time spent with the patient or family. If more than half of the time is spent on counseling or care coordination, this must be documented appropriately.
5. How does medical decision-making impact coding?
The complexity of medical decision-making directly influences the CPT code. The higher the complexity—based on the number of problems being managed, the amount of data reviewed, and the risk level—the higher the code and reimbursement rate.
6. Can these CPT codes be used for follow-up visits?
No, CPT 99202-99205 are only for new patient visits. Follow-up visits for established patients are coded differently (e.g., 99211-99215).
7. What should be documented for CPT 99203, 99204, and 99205?
To accurately bill for these codes, providers must document a detailed history, comprehensive physical examination, and medical decision-making complexity. Time spent with the patient, especially if counseling or coordination of care accounts for more than 50% of the visit, should also be documented.
