Unspecified ovarian pregnancy with intrauterine pregnancy

This code describes a rare and complex obstetric condition where an ovarian pregnancy coexists with a separate, viable intrauterine pregnancy. It signifies that the specific location within the ovary is not documented, nor is the laterality (left or right ovary) specified.

Apply this code when documentation confirms both an ovarian ectopic pregnancy and a concurrent intrauterine pregnancy, but lacks further detail regarding the ovarian site. This diagnosis is typically made via ultrasound and confirmed by surgical findings.

• Ensure documentation clearly states both an ovarian and an intrauterine pregnancy are present.
• If laterality (left or right ovary) or specific ovarian site is documented, use a more specific code from the O00.21- subcategory.
• This code should be sequenced as the primary diagnosis when it is the reason for the encounter, followed by codes for any associated complications.
