About ICD-9-CM 255.2
255.2 is an ICD-9-CM diagnosis code for adrenogenital disorders. 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 3 ICD-10-CM codes, such as E25.0 (Congenital adrenogenital disorders associated with enzyme deficiency), E25.8 (Other adrenogenital disorders) and E25.9 (Adrenogenital disorder, unspecified). All of these are approximate matches, so review the record to pick the right one.
