An OPPS status indicator is assigned to every HCPCS code. The status indicator identifies whether the service described by the HCPCS code is paid under the OPPS and if so, whether payment is made separately or packaged. The status indicator may also provide additional information about how the code is paid under the OPPS or under another payment system or fee schedule. For example, services with status indicator A are paid under a fee schedule or payment system other than the OPPS. Services with status indicator N are paid under the OPPS, but their payment is packaged into payment for a separately paid service. Services with status indicator T are paid separately under OPPS but a multiple procedure payment reduction applies when two or more services with a status indicator of T are billed on the same date of service.
The full list of status indicators and their definitions is published in Addendum D1 of the OPPS/ASC proposed and final rules each year. The status indicator for each HCPCS code is shown in OPPS Addendum B.
