Matern care for abnlt fetl hrt rate or rhym, 2nd tri, fts2

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 the second fetus in a multiple gestation. This includes conditions such as fetal bradycardia, tachycardia, or arrhythmias detected through monitoring.

Apply this code when documentation indicates maternal care for a fetal cardiac rhythm disturbance affecting fetus 2, specifically identified between 14 weeks 0 days and 27 weeks 6 days of gestation. Supporting documentation should include findings from fetal heart rate monitoring (e.g., nonstress test, biophysical profile, fetal echocardiogram) and the trimester of care.

• Ensure the documentation clearly specifies "fetus 2" in a multiple gestation and that the care occurred during the second trimester.
• Do not use this code for abnormalities of fetal growth or other non-cardiac fetal conditions.
• Sequence this code as a primary diagnosis when the maternal care is primarily focused on managing the fetal heart rate abnormality.
