About ICD-9-CM 235.5
235.5 is an ICD-9-CM diagnosis code for neoplasm of uncertain behavior of other and unspecified digestive organs. 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 D37.8 (Neoplasm of uncertain behavior of other specified digestive organs) and D37.9 (Neoplasm of uncertain behavior of digestive organ, unspecified). All of these are approximate matches, so review the record to pick the right one.
