Matern care for abnlt fetl hrt rate or rhym, 2nd tri, unsp

This code signifies medical supervision and intervention provided to a pregnant patient during her second trimester due to an identified abnormality in the fetal heart rate or rhythm. This includes conditions like fetal bradycardia, tachycardia, or arrhythmias that require monitoring or management by the maternal care team.

Apply this code when documentation indicates maternal care for a fetal heart rate or rhythm abnormality detected between 14 weeks 0 days and 27 weeks 6 days gestation. This would be used when the specific type of abnormality is not documented or is considered unspecified, and no specific intervention or outcome is noted as applicable.

• Always confirm the trimester of pregnancy from the medical record.
• If a more specific fetal heart rate abnormality is documented (e.g., specific arrhythmia), a more precise code from the O36.83- subcategory should be used.
• This code is for maternal care; do not use it for fetal conditions coded from Chapter 16 (P00-P96).
