O34Maternal care for abnormality of pelvic organs

Non-billable headerICD-10-CM

O34 is a non-billable header ICD-10-CM code for maternal care for abnormality of pelvic organs. It cannot be billed on its own: choose one of the more specific child codes below.

Code first

The underlying condition must be sequenced before this code.

  • any associated obstructed labor (O65.5)

Use additional code

Add a secondary code to capture the detail described below.

  • code for specific condition

Includes

Conditions this code covers.

  • the listed conditions as a reason for hospitalization or other obstetric care of the mother, or for cesarean delivery before onset of labor

Other codes that can never be billed with O34

These codes carry an Excludes1 note pointing at O34. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O34 alone.

  • N81Female genital prolapse
  • N85.4Malposition of uterus
  • N85.AIsthmocele
  • N88.3Incompetence of cervix uteri
  • Z98.891History of uterine scar from previous surgery

Risk adjustment

O34 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 O34

10 child codes. Green means billable.
