O77.0Labor and delivery complicated by meconium in amniotic fluid

O77.0 is the ICD-10-CM diagnosis code for labor and delivery complicated by meconium in amniotic fluid. It belongs to category O77 (other fetal stress complicating labor and delivery), block O60-O77 (complications of labor and delivery) and chapter 15 (pregnancy, childbirth and the puerperium). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within O77 (other fetal stress complicating labor and delivery), O77.0 is specifically for labor and delivery complicated by meconium in amniotic fluid. Related codes cover fetal stress in labor or delivery due to drug administration (O77.1), labor and delivery complicated by other evidence of fetal stress (O77.8) and labor and delivery complicated by fetal stress, unspecified (O77.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 998 (Principal Diagnosis Invalid as Discharge Diagnosis), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor treats this as a maternity diagnosis, expected only for patients age 9 through 64.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 656.81 (other specified fetal and placental problems, affecting management of mother, delivered, with or without mention of antepartum condition).
