About ICD-9-CM 656.81
656.81 is an ICD-9-CM diagnosis code for other specified fetal and placental problems, affecting management of mother, 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 8 ICD-10-CM codes, such as O36.8310 (Maternal care for abnormalities of the fetal heart rate or rhythm, first trimester, not applicable or unspecified), O36.8320 (Maternal care for abnormalities of the fetal heart rate or rhythm, second trimester, not applicable or unspecified) and O36.8330 (Maternal care for abnormalities of the fetal heart rate or rhythm, third trimester, not applicable or unspecified). All of these are approximate matches, so review the record to pick the right one.
