O77.8Labor and delivery complicated by other evidence of fetal stress

Billable / specific codeICD-10-CM

O77.8 is a billable, specific ICD-10-CM code for labor and delivery complicated by other evidence of fetal stress. It is valid for submission on a claim.

Excludes1 — never code together

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

  • abnormality of fetal acid-base balance (O68)
  • abnormality in fetal heart rate or rhythm (O76)
  • fetal metabolic acidemia (O68)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Labor and delivery complicated by electrocardiographic evidence of fetal stress
  • Labor and delivery complicated by ultrasonic evidence of fetal stress

Other codes that can never be billed with O77.8

These codes carry an Excludes1 note pointing at O77.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O77.8 alone.

  • O68Labor and delivery complicated by abnormality of fetal acid-base balance
  • O76Abnormality in fetal heart rate and rhythm complicating labor and delivery

Risk adjustment

O77.8 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.

How O77.8 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to O77.8.
