Home Births (CPB 0329, reviewed 2026-05-21)
Historical (last reviewed 05/21/2026): Aetna considers planned deliveries at home and associated services not medically appropriate. Coverage of home births will be considered only when mandated by law under plans subject to state mandates. The listed vaginal and cesarean delivery codes, newborn care in a setting other than a hospital or birthing center, nursing care in the home, and certain pregnancy and postpartum diagnosis codes are marked not covered for planned deliveries at home.

Maternal Biomarker Screening for Fetal Conditions (CPB 0464, reviewed 2026-07-17)
Aetna covers cell-free DNA fetal RhD genotyping when the pregnancy may be at risk for alloimmunization, paternal antigen typing is unavailable or heterozygous, and amniocentesis is declined or contraindicated. Multiple serum marker testing is covered for pregnant women who have been adequately counseled and want information on their risk of having a Down syndrome fetus, and NIPT for fetal aneuploidy (trisomy 13, 18 and 21, and sex chromosome aneuploidy) is covered for all pregnant women with the listed tests. Performing more than one screening test, such as NIPT with multiple marker screening, is considered not medically necessary, and cell-free DNA screening for microdeletion syndromes, rare autosomal trisomies, single-gene and multi-gene screening, and other listed approaches are considered experimental, investigational, or unproven.
