Procedure Clusters associated with Diagnostic Related Groups (DRG).  
This file should not be modified locally.  
Clusters or Groups of Procedures that in combination affect the DRG 
calculations.  
  
All the Procedures in a cluster must be associated with a patient record 
for the cluster to be applied to the DRG calculation of that record.  The 
set of Procedures in a cluster act as a single Procedure when determining 
if a Code Set is satisfied.
