Which code is used for an established patient visit in outpatient settings?

The correct code for an established patient visit in outpatient settings is found within the range of CPT 99211-99215. These codes specifically represent various levels of service for established patients, allowing healthcare providers to bill for evaluation and management (E/M) services based on the complexity and time spent with the patient.

CPT codes 99211-99215 correspond to different levels of care. For instance, 99211 is typically used for a minimal visit that involves a straightforward issue, while 99215 represents a more comprehensive encounter that requires a higher level of decision-making and complexity in the patient's condition. This range is specifically designated for established patients, distinguishing it from codes used for new patients or more specialized inpatient services.

In contrast, the other provided codes span different categories. The codes 99201-99205 are designated for new patient visits, while 99221-99225 are for initial hospital care, and 99231-99235 pertain to subsequent hospital visits. Since the question specifies outpatient settings for established patients, the option of 99211-99215 is the most appropriate choice.
