Is O76 a billable ICD-10-CM code?

Yes. O76 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does O76 sit in the tabular list?

Pregnancy, childbirth and the puerperium (O00-O9A), in the block Complications of labor and delivery (O60-O77).

What cannot be coded together with O76?

O76 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

O76

O76 — Abnormality in fetal heart rate and rhythm complicating labor and delivery

Billable / specific codeICD-10-CM

O76 is a billable, specific ICD-10-CM code for abnormality in fetal heart rate and rhythm complicating labor and delivery. 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.

fetal stress NOS (O77.9)
labor and delivery complicated by electrocardiographic evidence of fetal stress (O77.8)
labor and delivery complicated by ultrasonic evidence of fetal stress (O77.8)

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.

fetal metabolic acidemia (O68)
other fetal stress (O77.0-O77.1)

Inclusion terms

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

Depressed fetal heart rate tones complicating labor and delivery
Fetal bradycardia complicating labor and delivery
Fetal heart rate decelerations complicating labor and delivery
Fetal heart rate irregularity complicating labor and delivery
Fetal heart rate abnormal variability complicating labor and delivery
Fetal tachycardia complicating labor and delivery
Non-reassuring fetal heart rate or rhythm complicating labor and delivery

Other codes that can never be billed with O76

These codes carry an Excludes1 note pointing at O76. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O76 alone.

O77.8Labor and delivery complicated by other evidence of fetal stress
O77.9Labor and delivery complicated by fetal stress, unspecified

Risk adjustment

O76 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 O76 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 O76.
