The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as O15.02 (Eclampsia complicating pregnancy, second trimester), O15.03 (Eclampsia complicating pregnancy, third trimester) and O15.1 (Eclampsia complicating labor). All of these are approximate matches, so review the record to pick the right one.
