Procedures and Procedure Triggers: "have been created for optional use in a Procedures Section (entries required) (V2) Section contained in an Initial Public Health Case Report Document (eICR) (V4). They indicate that the procedure code is a trigger code and further constrain the following C-CDA R2.1 templates:"   There seem to be some extra words here. "Procedures Section (entries required) (V2) Section" seem to be better stated as "optional use in Procedures Section contained in an Initial Public Health Care Report Document (eICR)..."  The extra wording makes the statement hard to follow and the next paragraph is more simply stated.
