Must lay summaries of the "addendum" or "comparison" medical report be provided to all patients, even if there is no change in the findings or recommended course of action?

A lay summary of the “addendum” or “comparison” medical report must be provided to all patients even if there is no change in the findings or recommended course of action. For the specific case where there is no significant change in the report, a simple statement that the comparison has been performed and that there is no overall change would satisfy the requirement. If the “addendum” merely stated that the referring health care provider had been notified of the results of the patient’s examination, the addendum lay summary could be a simple statement informing the patient of that fact.
