About ICD-9-CM 936
936 is an ICD-9-CM diagnosis code for foreign body in intestine and colon. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as T18.3XXA (Foreign body in small intestine, initial encounter) and T18.4XXA (Foreign body in colon, initial encounter). All of these are approximate matches, so review the record to pick the right one.
