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

This code signifies ongoing maternal medical supervision due to an identified irregular fetal heart rate or rhythm in the third fetus of a multiple gestation pregnancy, when the specific trimester of detection is not documented. It indicates that the mother is receiving care focused on monitoring and managing this fetal cardiac abnormality.

Use this code when documentation specifies maternal care for an abnormal fetal heart rate or rhythm in the third fetus of a multiple gestation, and the trimester of diagnosis is not recorded. This applies to situations where the mother is being actively managed or monitored for this specific fetal condition. Supporting documentation would include physician notes detailing the fetal heart rate abnormality and the ongoing maternal care.

• Always strive for documentation of the specific trimester to allow for more precise coding (O36.831-, O36.832-, O36.833-).
• This code is for maternal care for the fetal condition; it does not code the fetal condition itself.
• Ensure the documentation clearly identifies the abnormality as belonging to the "fetus 3" in a multiple gestation.
