LOINC description : Code indicating basis of assignment of census tract or block numbering area (BNA)
for an individual record. Helpful in identifying cases tracted from incomplete information
or P.O. Box. Most of the time, this information is provided by a geocoding vendor
service. Alternatively, a central registry staff manually assigns the code. This item
is not coded by the hospital. Codes are hierarchical, with lower numbers having priority.
Note: Codes 1-5 and 9 are usually assigned by a geocoding vendor, while code 6 is
usually assigned through a special effort by the central registry... NAACCR Data Standards
