Aetna considers transabdominal cerclage medically necessary for treating an incompetent cervix when any of these apply: a deep traumatized cervix; previous failed transvaginal cerclages; a shortened (less than 2.5 cm) or amputated cervix; or transabdominal placement for cervical incompetence before conception by laparoscopy or laparotomy. A history consistent with incompetent cervix must be documented, including a history of mid-trimester pregnancy loss associated with painless cervical dilatation without evidence of uterine activity. Aetna considers transabdominal cerclage experimental, investigational, or unproven for all other indications, such as prophylactic cerclage for multiple gestations.

01Billing team: Before billing CPT 57700 (cervical incompetence prior to conception) or CPT 59325 (abdominal cerclage during pregnancy) for transabdominal cerclage, confirm the chart documents a history consistent with incompetent cervix and that the case fits a listed indication: deep traumatized cervix, previous failed transvaginal cerclage, shortened (less than 2.5 cm) or amputated cervix, or pre-conception laparoscopic or laparotomy placement.
02Match the diagnosis to ICD-10 code N88.3 for cervical incompetence or O34.30 to O34.33 and O34.40 to O34.43 for maternal care for cervical conditions.
03The policy lists multiple gestation codes O30.001 to O30.93 as not covered for these indications, and transabdominal cerclage for prophylactic cerclage in multiple gestations is treated as experimental, investigational, or unproven.
