O00.219 Unspecified ovarian pregnancy with intrauterine pregnancy

ICD-10-CM Code O00.219: Unspecified ovarian pregnancy with intrauterine pregnancy

ICD-10-CM code O00.219 identifies an unspecified ovarian pregnancy that occurs with a concurrent intrauterine pregnancy. Ovarian pregnancy is a form of ectopic pregnancy, and clinical literature notes it as a challenging diagnosis that can mimic other gynecological conditions. The code appears in external coding references alongside other ectopic pregnancy categories, though sources do not confirm its billable status or specific payer coverage rules. 1 2 3 4 5

Plain-language overview

Ovarian pregnancy is described as a challenging clinical phenomenon where the pregnancy develops outside the uterus, and it can mimic other gynecological or gastrointestinal conditions like appendicitis or ovarian torsion. 1 2

What this code represents

Code O00.219 is labeled as an unspecified ovarian pregnancy with intrauterine pregnancy, distinguishing it from codes for right or left ovarian pregnancies and from unspecified tubal pregnancies. 3 4

The code O00.219 is listed in external coding references within a broader sequence of ectopic pregnancy codes that includes both tubal and other unspecified ectopic pregnancies. 3 5

Clinical context

Clinical literature notes that an intrauterine pregnancy is definitively diagnosed by ultrasound visualization of a yolk sac or embryo, while an ectopic pregnancy can be accompanied by a fluid collection called a pseudosac. 2

Factors associated with extrauterine pregnancy in in vitro fertilization include tubal infertility, fresh embryo transfer compared to frozen, cleavage stage compared to blastocyst stage embryos, and a large number of transferred embryos. 1

Documentation considerations

External coding references list distinct codes for right ovarian pregnancy with intrauterine pregnancy and left ovarian pregnancy with intrauterine pregnancy, while O00.219 lacks a specified side. 3 4

Coverage and utilization context

Code O00.219 appears in a document titled ICD-10-CM Codes for Abortion-Related Services, which lists the code alongside other ectopic pregnancy diagnoses without detailing specific coverage criteria. 4

What the sources add

While clinical sources describe the diagnosis and management of ovarian pregnancy, external coding references provide the specific code O00.219 and its neighboring codes for unspecified and laterally specified ovarian pregnancies. 1 3

The carepatron.com source and the healthnetcalifornia.com source both list O00.219 with the identical label of unspecified ovarian pregnancy with intrauterine pregnancy, showing consistency across these two external coding references. 3 4
