Which code is assigned when there is a complication present in a high-risk pregnancy?

The appropriate code for a high-risk pregnancy with complications is O09. This code specifically pertains to complications arising in a high-risk pregnancy, encompassing various conditions and circumstances that can affect both the mother and the fetus. High-risk pregnancies may involve pre-existing maternal conditions, complications from prior pregnancies, or medical issues that develop during the current pregnancy.

The other codes serve different purposes. O80 refers to a normal delivery without complications, which does not apply to a high-risk situation. Z34 is a code used for supervision of a normal pregnancy, indicating that it is tracking a non-complicated pregnancy rather than addressing any complications. O00 is related to ectopic pregnancy, which is a specific condition rather than a general complication of pregnancy.

Thus, O09 is specifically created for documenting complications present in high-risk pregnancies, ensuring accurate medical coding and facilitating appropriate care management.
