Composite Ambulatory Payment Classification (APC) Processing under the Outpatient Prospective Payment System (OPPS)
As composite APCs become more prevalent and are expanded to a variety of services, there exists a greater potential for a single line to meet the requirements for more than one Payment Adjustment Flag value. Therefore, effective for dates of service on or after January 1, 2009, the I/OCE shall create a new Composite Adjustment Flag in the APC Return Buffer.
