Just as you are the first line of defense for your patients’ health, accurate medical coding is your frontline protection against claim denials. In primary care, Current Procedural Terminology (CPT) coding can be intricate. Primary care providers tackle a wide array of services daily, from routine check-ups to complex diagnoses and treatments. Translating these diverse services into precise 5-digit CPT codes is crucial for proper billing and reimbursement.
Navigating the hundreds of CPT codes applicable to primary care—covering everything from office visits and diagnostic tests to preventive care and vaccinations—can feel overwhelming. This guide highlights the most commonly used primary care CPT codes, ensuring you’re well-equipped for efficient and accurate medical coding.
Top CPT Codes for Primary Care Evaluation and Management (E/M) Visits
Evaluation and Management (E/M) codes are the bedrock of primary care billing. These codes represent the cognitive and physical work physicians perform in evaluating and managing a patient’s health. Here are the most frequently used E/M codes for both new and established patients in outpatient settings.

|---|---|---|---|
| 99202 | Outpatient visit with a new patient requiring a straightforward level of medical decision making. Includes history, examination, and simple decision-making. | 15 minutes | Straightforward |

| 99212 | Outpatient visit with an established patient requiring a straightforward level of medical decision making. Direct physician interaction for routine follow-up or simple issues. | 10 minutes | Straightforward |
| 99213 | Outpatient visit with an established patient requiring a low level of medical decision making. For managing stable chronic conditions or minor acute problems. | 20 minutes | Low Complexity |
| 99214 | Outpatient visit with an established patient requiring a moderate level of medical decision making. For patients with moderate complexity, potentially involving treatment plan adjustments. | 30 minutes | Moderate Complexity |
| 99215 | Outpatient visit with an established patient requiring a high level of medical decision making. For managing complex or unstable chronic conditions, or significant acute issues. | 40 minutes | High Complexity |
