Maternal care for unstable lie, fetus 1

This code describes antenatal care provided to a pregnant patient whose first fetus (or only fetus in a singleton pregnancy) is presenting in an unstable lie. An unstable lie refers to a fetal position that changes frequently, such as from transverse to oblique, and is not fixed in a longitudinal or transverse presentation. This condition increases the risk of complications during labor and delivery.

Use this code when documentation indicates maternal care for an unstable fetal lie, specifically for the first fetus. This typically involves increased monitoring, counseling, and potential interventions to manage the fetal position. Documentation should clearly state "unstable lie" and specify it pertains to fetus 1.

• Ensure documentation specifies "fetus 1" or indicates a singleton pregnancy if only one fetus is present.
• Do not confuse with codes for specific malpresentations (e.g., O32.1XX0 for breech, O32.2XX0 for transverse lie) if the lie is not yet fixed.
• This code is for maternal care related to the unstable lie; additional codes may be needed for any associated complications or procedures.
