- Medical history review focused on the current problem.

- Examination focused on the affected body area or system related to the problem.

- Limited discussion of the diagnosis, treatment plan, and prognosis.

- Coding requirements for 99203:

- The medical history, exam, and medical decision-making are all limited in scope.

99213: Office or other outpatient visit, established patient, detailed.

In summary, 99203 is used for focused visits with established patients involving a single, uncomplicated problem, while 99213 is used for more comprehensive visits with established patients involving complex medical issues or multiple coexisting problems. The choice of code depends on the complexity of the patient's condition and the time spent by the physician in providing care.
