O04Complications following (induced) termination of pregnancy

Non-billable headerICD-10-CM

O04 is a non-billable header ICD-10-CM code for complications following (induced) termination of pregnancy. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • encounter for elective termination of pregnancy (Z33.2)
  • failed attempted termination of pregnancy (O07.-)

Includes

Conditions this code covers.

  • complications following (induced) termination of pregnancy

Other codes that can never be billed with O04

These codes carry an Excludes1 note pointing at O04. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O04 alone.

  • O04.87Sepsis following (induced) termination of pregnancy
  • O04.5Genital tract and pelvic infection following (induced) termination of pregnancy
  • O04.81Shock following (induced) termination of pregnancy
  • O22Venous complications and hemorrhoids in pregnancy
  • O88Obstetric embolism

Risk adjustment

O04 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead O04

4 child codes. Green means billable.
