About ICD-9-CM 938
938 is an ICD-9-CM diagnosis code for foreign body in digestive system, unspecified. 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 T18.8XXA (Foreign body in other parts of alimentary tract, initial encounter) and T18.9XXA (Foreign body of alimentary tract, part unspecified, initial encounter). All of these are approximate matches, so review the record to pick the right one.
