True or False: A procedure record is necessary to document a historical immunization.

In the context of documenting historical immunizations, it is accurate to state that a procedure record is not necessary for every instance. While it is important to keep comprehensive records of immunizations, historical immunizations—those that were administered before a current treatment encounter—can typically be documented without creating a new procedure record.

In many electronic health record systems, including Epic, historical immunization data can often be entered or pulled from existing databases, allowing healthcare providers to maintain a complete immunization history without the need for a specific procedure record for each historical entry. This distinguishes the documentation approach used for active or newly administered immunizations, which do require a procedure record, from those that are merely being referenced in a patient's history.

Therefore, the statement correctly indicates that a procedure record is not necessary to document a historical immunization, confirming the answer as true.
