Beneficiary Data Streamlining (BDS)
20.2.1 - Beneficiary Data Streamlining (BDS)
(Rev. 4009, Issued: 03-23-18, Effective: 04-23-18, Implementation: 04-23-18)
The BDS system provides access to a common eligibility service which occurs earlier in
the claims lifecycle than the CWF eligibility check. The BDS transactions, 'HBDA' for
Part A, 'HBDB' for Part B, and 'HBDD' for DME, will allow the Shared Systems claims
processing to query eligibility edits for Part A, Part B, and DME claims. The BDS system
uses the CWF data repository to provide eligibility and entitlement responses to the
Shared Systems query. The information is returned on a BDS Basic Reply Record. (See
§20.3.1) BDS records can be of the following types:
• A/B MAC (A) Claim Record: A/B MAC (A) bills are input on the HBDA
record.
• A/B MAC (B) Claim Record: A/B MAC (B) bills are input on the HBDB record.
• DMEPOS Claim Record: DMEPOS bills are input on the HBDD record.
