Proposed Wording
Need to change the modeling of Diagnostic Order to make it a type of Order.

Comments
The modeling for a diagnostic order and the generalized order are needlessly dissimilar. The sequencing of elements is different; e.g. Identifier comes first in Order and is the third element in Diagnostic Order. What rule says an order for a Lab test needs a model unique and different from all other orders.

Would recommend that all orders derived from a base order and that Diagnostic Order simply profile or extend the base order model.

Need to sit down and explain the model to balloter.

Not Persuasive with Mod

Disposition Comment
Order is a workflow resource. It can point to DiagnosticOrder but it is not a specialization of Order. However, consistency in ordering of elements is reasonable
