Revenue Center Unit Count (FFS)

SAS Name

A quantitative measure (unit) of the number of times the service or procedure being reported was performed according to the revenue center/HCPCS code definition as described on an institutional claim.

Depending on type of service, units are measured by number of covered days in a particular accommodation, pints of blood, emergency room visits, clinic visits, dialysis treatments (sessions or days), outpatient therapy visits, and outpatient clinical diagnostic laboratory tests


When revenue center code = '0022' (SNF PPS) the unit count will reflect the number of covered days for each HIPPS code and, if applicable, the number of visits for each rehab therapy code.
