About ICD-9-CM 237.3
237.3 is an ICD-9-CM diagnosis code for neoplasm of uncertain behavior of paraganglia. 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 D44.6 (Neoplasm of uncertain behavior of carotid body) and D44.7 (Neoplasm of uncertain behavior of aortic body and other paraganglia). All of these are approximate matches, so review the record to pick the right one.
