ABSTRACT: The Version 54 Summary provides a synopsis, by topic, of the changes that will be contained in Transmittal 87 of the CABS Billing Outputs Specifications (BOS). The Version Summary explains, on an item-by-item approach, the changes being made for a particular version. This item-by-item approach avoids a review of the entire CABS BOS to determine what changes are being incorporated. It is a stand-alone document primarily intended for programmers, analysts, and spec writers. The Version 54 Summary addresses the incorporation of a new phrase code to bill for reconcilliation of payment plans, incorporation of a default value for the Discount Application Indicator and the addition of an existing element (Reciprocal Compensation Charge Type Ind) was added to the 10-39-10 (Unbundled End Office Usage Detail) record to show when the Reciprocal Compensation terminating rate is being used. Version 54 becomes effective September 2014.
