What is an example of a Category I code for a physical examination?

The choice of 99213 as a Category I code for a physical examination is appropriate because it specifically refers to an office visit for an established patient, where a level of medical decision-making and evaluation is conducted. This code reflects the process of assessing a patient’s health, which is a key component of a physical examination.

In the context of CPT codes, Category I codes represent procedures and services that are widely accepted and used in clinical practice, which includes office visit evaluations like 99213. Established patient visits typically involve a review of systems, a medical history update, and a physical examination, all of which fall under the activity characterized by this code.

Other choices, while they are important medical procedures, do not represent a physical examination in the same way. For example, 93000 pertains to an electrocardiogram, which is a diagnostic test rather than an evaluation of overall health. The code 20610 refers to an arthrocentesis, a specific procedure involving the joint that is not a comprehensive examination. Lastly, 36415, which covers the collection of a venous blood sample, is also more procedural in nature rather than encompassing the comprehensive evaluation typically associated with a physical examination.
