If the bleeding is controlled in the duodenum, do you choose the CPT by the instrument used: upper EGD scope versus pediatric colonoscope? How far does the exam need to reach in order to qualify for 44366? CPT states:44366= beyond second part of duodenum, not including ileum/ and 43255 = duodenum or jejunum.
If procedure is done in duodenum, either code seems to cover that area. What other detail would support the code choice?
