_(<patient> not found, generate \[max + 1\])_
\\
If the <patient_id> source in the <patient> object is not 'HIVE' *and* the _PATIENT_ID source_ ('MGH') *and* value ('123') combination do not exist, then a new PATIENT_NUM with value max (patient_num)+1 will be generated. All the PATIENT_NUMs for this patient will receive this value. The new patient number must also be added to the PATIENT_DIMENSION table
\\
*_+Example{+}:_*
New <patient_id> source / value pair = 'MGH' / 123
Select max(patient_num) from patient_mapping = 527
New patient_num = max(patient_num) + 1 = 528
