About ICD-9-CM 651.73
651.73 is an ICD-9-CM diagnosis code for multiple gestation following (elective) fetal reduction, 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 O31.31X0 (Continuing pregnancy after elective fetal reduction of one fetus or more, first trimester, not applicable or unspecified), O31.32X0 (Continuing pregnancy after elective fetal reduction of one fetus or more, second trimester, not applicable or unspecified) and O31.33X0 (Continuing pregnancy after elective fetal reduction of one fetus or more, third trimester, not applicable or unspecified). All of these are approximate matches, so review the record to pick the right one.
