About O08

O08 is the ICD-10-CM diagnosis code for complications following ectopic and molar pregnancy. It belongs to block O00-O08 (pregnancy with abortive outcome) 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: O08.0 (pregnancy), O08.1 (pregnancy), O08.2 (pregnancy), O08.3 (pregnancy), O08.4 (pregnancy), O08.5 (pregnancy), O08.6 (pregnancy), O08.7 (pregnancy) 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.
