Matern care for abnlt fetl hrt rate or rhym, 2nd tri, fts3

This code signifies medical attention provided to a pregnant patient in her second trimester due to an abnormal heart rate or rhythm detected in the third fetus of a multiple gestation pregnancy. This includes conditions such as fetal bradycardia, tachycardia, or arrhythmias requiring maternal monitoring or intervention.

Apply this code when documentation specifies maternal care for an identified cardiac rhythm abnormality in the third fetus during the second trimester. Supporting documentation includes fetal monitoring strips, ultrasound reports detailing fetal heart activity, and physician notes indicating the trimester and specific fetus affected.

• Ensure the documentation clearly identifies the third fetus in a multiple gestation and the second trimester.
• Do not use for abnormalities of fetal heart rate or rhythm in singletons or other fetal positions.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the maternal care for this specific fetal condition.
