About O26
O26 is the ICD-10-CM diagnosis code for maternal care for other conditions predominantly related to pregnancy. It belongs to block O20-O29 (other maternal disorders predominantly related to pregnancy) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: O26.0 (pregnancy), O26.1 (pregnancy), O26.2 (loss), O26.3 (pregnancy), O26.4 (gestationis), O26.5 (syndrome), O26.6 (puerperium), O26.7 (puerperium) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
