Maternal care for cervical incompetence, third trimester

This code signifies ongoing medical management and surveillance for a pregnant patient diagnosed with cervical incompetence during her third trimester. Cervical incompetence refers to the premature dilation and effacement of the cervix, which can lead to preterm birth or pregnancy loss. This code specifically captures the maternal care provided for this condition in the later stages of pregnancy.

Apply this code when a pregnant patient in her third trimester is receiving active management for a previously diagnosed or newly identified incompetent cervix. Documentation should clearly indicate the diagnosis of cervical incompetence and the gestational age falling within the third trimester (typically 28 weeks gestation to delivery). This includes care for cerclage placement, progesterone therapy, or close monitoring due to this condition.

• Ensure documentation explicitly states "third trimester" or provides a gestational age within the third trimester.
• Do not use this code for cervical incompetence diagnosed and managed in the first or second trimester; specific codes exist for those trimesters.
• Code any associated procedures, such as cerclage, separately.
