About ICD-9-CM 646.24
646.24 is an ICD-9-CM diagnosis code for unspecified renal disease in pregnancy, without mention of hypertension, postpartum 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 2 ICD-10-CM codes, such as O12.15 (Gestational proteinuria, complicating the puerperium) and O90.89 (Other complications of the puerperium, not elsewhere classified). All of these are approximate matches, so review the record to pick the right one.
