About ICD-9-CM 45.51

45.51 is an ICD-9-CM procedure code for isolation of segment of small intestine. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.

The CMS General Equivalence Mappings translate it to 7 ICD-10-PCS codes, such as 0D160ZB (Bypass Stomach to Ileum, Open Approach), 0DB80ZZ (Excision of Small Intestine, Open Approach) and 0DB90ZZ (Excision of Duodenum, Open Approach). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
