Matern care for abnlt fetl hrt rate or rhym, 2nd tri, fts5

This code signifies antenatal care provided to a pregnant patient in her second trimester due to an identified abnormality in the heart rate or rhythm of the fifth fetus in a multiple gestation pregnancy. This includes conditions such as fetal bradycardia, tachycardia, or arrhythmias detected during routine monitoring or diagnostic testing.

Apply this code when documentation clearly indicates maternal care for a fetal heart rate or rhythm abnormality specifically affecting the fifth fetus during the second trimester. Supporting documentation includes ultrasound reports, fetal monitoring strips, and physician notes detailing the abnormal finding and the gestational age.

• Ensure the documentation specifies "fetus 5" in a multiple gestation and that the gestational age falls within the second trimester (14 weeks 0 days to 27 weeks 6 days).
• Do not use this code for abnormalities of the fetal heart structure; use codes from category Q20-Q28 for congenital anomalies of the circulatory system.
• Sequence this code as a secondary diagnosis following the primary obstetric code indicating the reason for the encounter.
