Maternal care for unstable lie, not applicable or unsp

This code signifies antenatal care provided to a pregnant patient whose fetus is presenting in an unstable lie, meaning the fetal position frequently changes and is not fixed in a longitudinal or transverse orientation. This condition poses a risk for malpresentation at the onset of labor.

Apply this code when documentation indicates maternal care for an unstable fetal lie, and further specificity regarding the encounter (e.g., fetus affected by unstable lie, maternal care for unstable lie with a successful external cephalic version) is not provided or not applicable. This code is appropriate when the unstable lie is the primary reason for the maternal care encounter.

• Ensure documentation clearly states "unstable lie" and that the care is maternal, not fetal-specific.
• Do not use this code if a more specific code for an unstable lie, such as one indicating a successful external cephalic version, is available.
• This code is for the maternal condition; a separate code for any fetal condition (e.g., malposition) would be reported if applicable.
