O43.2: Morbidly adherent placenta

Non-billable headerICD-10-CM

O43.2 is a non-billable header ICD-10-CM code for morbidly adherent placenta. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • retained placenta (O73.-)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

  • associated third stage postpartum hemorrhage, if applicable (O72.0)

Excludes2 inherited from the categories above O43.2

Not part of this code, but both may be coded when both are present.

Written on O43: Placental disorders

  • maternal care for poor fetal growth due to placental insufficiency (O36.5-)
  • placenta previa (O44.-)
  • placental polyp (O90.89)
  • placentitis (O41.14-)
  • premature separation of placenta [abruptio placentae] (O45.-)

Other codes that can never be billed with O43.2
