Territories & States Beneficiary Query (TBQ) File


The Territory & States Beneficiary Query (TBQ) is a data exchange between CMS and states or territories. States and territories query CMS for detailed Medicare beneficiary information on Medicare Parts A, B, C, and D eligibility and enrollment.

The Medicare Advantage Prescription Drug (MAPD) State Users Guide (SUG) (Version 7.0 (02/28/2018)) includes the following information on TBQ files:

  • Section 10, Territory & States Beneficiary Query Request File
  • Section 11, Territory & States Beneficiary Query Response File

More information about the TBQ process can be found in the Medicare Beneficiary Database Suite of Systems (MBDSS) Interface Control Document (ICD) TBQ (Version 5.5 (06/21/2017)).
