651.90 — Unspecified multiple gestation, unspecified as to episode of care or not applicable

651.90 is an ICD-9-CM diagnosis code for unspecified multiple gestation, 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 O30.90 (Multiple gestation, unspecified, unspecified trimester) and O31.8X90 (Other complications specific to multiple gestation, unspecified trimester, not applicable or unspecified). All of these are approximate matches, so review the record to pick the right one.
