Which billing code corresponds to a detailed exam with moderate complexity?

In the context of billing for medical services, the code that corresponds to a detailed exam with moderate complexity is indeed significant. The coding system used primarily here is the Current Procedural Terminology (CPT), which categorizes evaluation and management (E/M) services based on the complexity and intensity of the clinical encounters.

The 99204 code specifically refers to an outpatient visit for the evaluation and management of a new patient, requiring a detailed history, a detailed examination, and medical decision-making of moderate complexity. This classification indicates that the healthcare provider has performed an in-depth assessment, which requires a good understanding of the patient's history and current health status.

In contrast, codes like 99201 and 99202 generally pertain to less complex patient interactions, where either a straightforward or low-complexity evaluation is warranted. Meanwhile, 99203 also indicates a moderate level of complexity but aligns with a less detailed examination than what is specified for 99204. Therefore, 99204 accurately represents the criteria for a detailed exam accompanied by moderate complexity in the scenario presented. Understanding these distinctions is crucial for accurate billing and appropriate compensation for the services rendered.
