Suprvsn of preg w history of pre-term labor, second tri

This code signifies the ongoing medical oversight of a pregnant patient during her second trimester who has a documented history of preterm labor in a previous pregnancy. It indicates that the current pregnancy is being managed with increased vigilance due to this significant risk factor for recurrent preterm delivery.

Apply this code when a pregnant patient in her second trimester is receiving antenatal care and her medical history explicitly records a prior preterm labor event. Documentation should clearly state the history of preterm labor and confirm the current gestational age falls within the second trimester (typically weeks 14 through 27).

• Ensure documentation specifies "history of preterm labor," not just "preterm birth," as the latter may not always imply labor.
• Verify the current pregnancy is indeed in the second trimester; codes exist for other trimesters.
• This code is for supervision only; if actual preterm labor is occurring, a different code from the O60 category would be more appropriate.
