The UB2 segment contains data necessary to complete UB92 bills specific to the United States; other realms may choose to implement using regional code sets. Only UB92 fields that do not exist in other HL7 defined segments appear in this segment. For example, Patient Name and Date of Birth are required; they are included in the PID segment and therefore do not appear here. UB92 field locators are provided in parentheses ( ). The UB codes listed as examples are not an exhaustive or current list; refer to a UB specification for additional information.

The Uniform Billing segments are specific to the US and may not be implemented in non-US systems.
