About ICD-9-CM 648.83
648.83 is an ICD-9-CM diagnosis code for abnormal glucose tolerance of mother, antepartum condition or complication. 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 O24.415 (Gestational diabetes mellitus in pregnancy, controlled by oral hypoglycemic drugs), O24.419 (Gestational diabetes mellitus in pregnancy, unspecified control) and O99.810 (Abnormal glucose complicating pregnancy). All of these are approximate matches, so review the record to pick the right one.
