About ICD-9-CM 651.81
651.81 is an ICD-9-CM diagnosis code for other specified multiple gestation, delivered, with or without mention of antepartum condition. 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 6 ICD-10-CM codes, such as O30.801 (Other specified multiple gestation, unspecified number of placenta and unspecified number of amniotic sacs, first trimester), O30.802 (Other specified multiple gestation, unspecified number of placenta and unspecified number of amniotic sacs, second trimester) and O30.803 (Other specified multiple gestation, unspecified number of placenta and unspecified number of amniotic sacs, third trimester). All of these are approximate matches, so review the record to pick the right one.
