Changes made to the gray boxes in the guide regarding when and how Critical Care contact information is sent creates a possible reject situation if all the contact information segments are not included.
Reason:
The gray boxes need to accommodate an instance where the contact information loop can be sent without some of the segments. An example of this would be if the contact information becomes optional in the PUCT form and if the customer only provides an address with no phone number. The guide as written requires that all the segments be present if the loop is sent.
