Maternal care for unstable lie, fetus 2

This code signifies antenatal care provided to a pregnant patient whose second fetus (in a multiple gestation) is presenting in an unstable or abnormal lie, such as transverse or oblique, which can change frequently. This condition increases the risk of complications during labor and delivery, necessitating close monitoring and management.

Apply this code when documentation indicates maternal care for an unstable fetal lie specifically for the second fetus in a multiple gestation pregnancy. This typically involves ongoing assessment of fetal position and planning for delivery. Documentation should clearly specify "fetus 2" or "second fetus" and the unstable lie.

• Ensure the documentation explicitly identifies the unstable lie as pertaining to the second fetus.
• Do not confuse with codes for unstable lie of a single fetus or other specific malpresentations.
• This code is typically a secondary diagnosis, with the primary diagnosis often related to the multiple gestation itself (e.g., O30.0-).
