The Current Procedural Terminology (CPT) code 99204 designates a specific level of evaluation and management (E/M) service for a new patient in an office or other outpatient setting. This code signifies a comprehensive history and examination, coupled with moderate complexity in medical decision-making. As an example, this code might be applied when a physician sees a new patient presenting with a complex medical history and multiple chronic conditions requiring a thorough workup and management plan.
Accurate application of this code is vital for appropriate reimbursement and compliance with coding guidelines. Correct usage ensures that healthcare providers are fairly compensated for the cognitive effort and resources expended during patient encounters. Historically, E/M coding has undergone revisions to clarify requirements and reduce ambiguity, emphasizing the importance of precise documentation to support the level of service billed.
