About ICD-9-CM 656.80

656.80 is an ICD-9-CM diagnosis code for other specified fetal and placental problems, affecting management of mother, unspecified as to episode of care or not applicable. 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 4 ICD-10-CM codes, such as O36.8390 (Maternal care for abnormalities of the fetal heart rate or rhythm, unspecified trimester, not applicable or unspecified), O36.8990 (Maternal care for other specified fetal problems, unspecified trimester, not applicable or unspecified) and O68 (Labor and delivery complicated by abnormality of fetal acid-base balance). All of these are approximate matches, so review the record to pick the right one.
