678.00 — Fetal hematologic conditions, unspecified as to episode of care or not applicable

678.00 is an ICD-9-CM diagnosis code for fetal hematologic conditions, 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 2 ICD-10-CM codes, such as O35.8XX0 (Maternal care for other (suspected) fetal abnormality and damage, not applicable or unspecified) and O36.8290 (Fetal anemia and thrombocytopenia, unspecified trimester, not applicable or unspecified). All of these are approximate matches, so review the record to pick the right one.
