Matern care for known or susp placntl insuff, 2nd tri, fts3

This code signifies ongoing maternal medical management and surveillance due to a confirmed or highly suspected inadequacy of placental function during the second trimester of pregnancy. This insufficiency can compromise fetal growth and well-being by limiting nutrient and oxygen transfer. The "fetus 3" designation indicates that the care is specifically for the third fetus in a multiple gestation pregnancy.

Apply this code when a pregnant patient in her second trimester is receiving specialized care for diagnosed or strongly suspected placental insufficiency, such as abnormal umbilical artery Doppler findings, oligohydramnios, or a history of prior placental complications. Documentation should clearly state the trimester, the suspected or confirmed placental issue, and specify that the care is directed at the third fetus in a multifetal pregnancy.

• Ensure the medical record explicitly identifies the second trimester and the specific fetus (fetus 3) for which the care is provided.
• Do not use this code for routine prenatal care; it is for additional maternal care due to the placental complication.
• Sequence this code as a principal diagnosis when the placental insufficiency is the primary reason for the encounter, or as a secondary diagnosis if another condition is the focus but placental insufficiency is also being managed.
