Abnormality in fetal heart rate and rhythm complicating labor and delivery
In Complications of labor and delivery (O60-O77), chapter 15: Pregnancy, Childbirth and the Puerperium
- O76 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under O60-O77 below.
- As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
- Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
- AHRQ's Chronic Condition Indicator classes it as not chronic (an acute or short-term condition).
- Expected only on maternity records. (Maternity list)
