Encounter for antenatal screening for cervical length

This code signifies an encounter where a pregnant patient undergoes screening to measure the length of her cervix. This assessment is performed to identify potential risks of preterm labor or other pregnancy complications related to cervical insufficiency.

Use this code when a pregnant patient presents for a routine or targeted ultrasound specifically to assess cervical length as a screening measure. This often occurs in the second trimester, particularly for patients with risk factors for preterm birth.

• This code is for screening purposes only; do not use if the patient has a confirmed diagnosis of cervical insufficiency or is being managed for active preterm labor.
• Always sequence this code as a secondary diagnosis when another condition or reason for the encounter is primary.
• Ensure supporting documentation clearly indicates the purpose of the visit was for cervical length screening.
