Matern care for abnlt fetl hrt rate or rhym, 2nd tri, fts1

This code signifies specialized obstetric care provided to a pregnant patient during her second trimester due to an identified abnormality in the heart rate or rhythm of a single fetus. This includes conditions such as fetal bradycardia, tachycardia, or arrhythmias detected during prenatal monitoring. The maternal care is specifically directed at managing the pregnancy in light of this fetal cardiac concern.

Use this code when documentation indicates maternal care for a fetal heart rate or rhythm abnormality (e.g., fetal arrhythmia, persistent bradycardia, or tachycardia) identified between 14 weeks 0 days and 27 weeks 6 days gestation. The medical record should clearly specify the fetal cardiac issue and the trimester of diagnosis or management. This code is appropriate for singleton pregnancies.

• Ensure the documentation specifies "second trimester" and refers to a single fetus.
• Do not use this code if the fetal heart rate abnormality is a transient finding without clinical significance or if it's related to a known fetal anomaly coded elsewhere.
• Consider sequencing this code as a principal diagnosis when the maternal care is primarily focused on the fetal cardiac issue, or as a secondary diagnosis when another condition is the primary reason for the encounter.
