Maternal care for cervical incompetence, second trimester

This diagnosis code signifies ongoing maternal care provided due to a weakened or prematurely dilating cervix during the second trimester of pregnancy. This condition, if untreated, can lead to preterm labor or miscarriage. The care focuses on monitoring and interventions to prolong the pregnancy.

Apply this code when a pregnant patient in her second trimester is receiving medical management or surgical interventions (e.g., cerclage) specifically for a diagnosis of cervical incompetence. Documentation should clearly state the diagnosis and the trimester of pregnancy.

• Ensure the documentation explicitly states "second trimester" for cervical incompetence; otherwise, a different trimester-specific code may be more appropriate.
• This code is for the maternal care related to the condition, not the condition itself in a non-pregnant state.
• Sequence this code as a primary diagnosis when the reason for the encounter is directly related to managing the cervical incompetence.
