80.3 - Beneficiary Other Insurance Information (HUBO) Maintenance
Transaction Error Codes
(Rev. 4009, Issued: 03-23-18, Effective: 04-23-18, Implementation: 04-23-18)
Effective January 2, 2007, the CWF shall accept and process a HUBO transaction that
either updates an existing Beneficiary Other Insurance (BOI) auxiliary record or adds a
new BOI auxiliary record occurrence.
If the CWF receives an incoming HUBO transaction whose COBA identification number
(ID) and ‘beneficiary supplemental eligibility-from date’ (CCYYMMDD) match the
equivalent elements within an existing BOI auxiliary record, it shall overlay the existing
record with the incoming record. However, if the CWF receives an incoming HUBO
transaction whereby the COBA ID and ‘beneficiary supplemental-from date’ do not match
the equivalent elements within an existing BOI auxiliary record, it shall create a new BOI
auxiliary record occurrence.
For purposes of applying COBA eligibility files to the BOI auxiliary file, the CWF
maintainer shall redefine Action Type ‘0- Add’ as ‘1-Add/Update.’ For purposes of
applying COBA eligibility files to the BOI auxiliary record, the CWF shall now accept and
process only two Action Types—‘1 - Add/Update’ and ‘2 – Delete’—from the BCRC as
part of the COBA crossover process.
The CWF shall continue to apply the applicable ‘BO’ edits that would relate to add/update
or delete actions accomplished via the HUBO transaction.
