About O34.59
O34.59 is the ICD-10-CM diagnosis code for maternal care for other abnormalities of gravid uterus. It belongs to category O34 (maternal care for abnormality of pelvic organs), block O30-O48 (maternal care related to the fetus and amniotic cavity and possible delivery problems) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
Within O34.5, choose O34.59 (other abnormalities of gravid uterus) only when documentation doesn't support a more specific option: incarceration of gravid uterus (O34.51), prolapse of gravid uterus (O34.52) and retroversion of gravid uterus (O34.53).
To report this condition, pick the subcode that matches the documentation: O34.591 (first trimester), O34.592 (second trimester), O34.593 (third trimester) and O34.599 (unspecified trimester).
Code first: any associated obstructed labor (O65.5).
Use an additional code for specific condition.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
