What the response or workflow means

How to use it operationally
Explain group codes, reason codes, amounts, and quantities as part of claim balancing. The information must remain consistent with related loops and segments. A change made late in the workflow—such as changing the subscriber relationship, diagnosis order, rendering provider, or service line—can require several connected elements to be rebuilt rather than one text value being replaced.
A realistic batch example
