Which of the following services is not included in Ambulatory Patient Classifications (APCs) for reimbursement?

Organ transplantation is not included in Ambulatory Patient Classifications (APCs) for reimbursement because APCs are designed specifically for outpatient services provided by hospitals, typically encompassing services that do not require an overnight stay. Organ transplantation, on the other hand, is a complex procedure that often requires inpatient care, as it involves pre-operative evaluations, the surgical procedure itself, and post-operative monitoring and care. This complexity and the need for extended hospital resources place organ transplantation outside the scope of APCs, which focus on more routine outpatient procedures.

In contrast, services such as radiation therapy, preventive services, and screening exams are appropriate for APC reimbursement. These services are typically performed in an outpatient setting and are more aligned with the criteria used to establish APCs, which aim to categorize outpatient hospital services for the purpose of enhanced reimbursement efficiency.
