Which of the following codes would NOT be reported for an inpatient hospital encounter?

The code that would not be reported for an inpatient hospital encounter is a specific evaluation and management (E/M) service code that corresponds to outpatient settings. The codes in question are all from the E/M section of the CPT codes, which are used to report various types of patient encounters based on the complexity and time spent on evaluation and management.

The selected answer pertains to 99213, which is used for an established outpatient visit. Codes like 99215 and 99222, on the other hand, are typically utilized for more complex visits and can be applicable to inpatient encounters, particularly as 99222 is often used for initial hospital visits requiring a higher level of medical decision-making. Similarly, 99224 is meant for subsequent hospital visits, indicating it is directly related to inpatient care.

In summary, the distinction lies in the fact that 99213 is reserved for outpatient care, making it inappropriate for reporting during an inpatient encounter. Inpatient encounters would require codes that apply specifically to hospital settings, which include comprehensive initial or subsequent visit codes, reflecting the nature of care provided in those environments.
