The type of facility.
This field, in combination with the service classification type code (variable called CLM_SRVC_CLSFCTN_TYPE_CD) indicates the “type of bill” for an institutional claim. Many different types of services can be billed on a Part A or Part B institutional claim, and knowing the type of bill helps to distinguish them.
The type of bill is the concatenation of two variables:
-facility type (CLM_FAC_TYPE_CD)
-service classification type (CLM_SRVC_CLSFCTN_TYPE_CD).
Note that sometimes 3 variables are used for “type of bill”, where the 3rd digit is the claim frequency code (CLM_FREQ_CD).
