Matern care for known or susp placntl insuff, unsp tri, oth

This code signifies antenatal care provided to a pregnant patient due to a known or suspected impairment of placental function, which could compromise fetal well-being. This insufficiency implies the placenta is not adequately supplying nutrients and oxygen to the fetus. The specific trimester of gestation is not documented, and the code applies to a pregnancy with multiple fetuses where the affected fetus is not specified.

Utilize this code when documentation indicates maternal care for placental insufficiency, but the specific trimester is not recorded, and the pregnancy involves multiple gestations without identifying which fetus is affected. This code is appropriate when the provider's assessment or diagnostic findings (e.g., abnormal Doppler studies, fetal growth restriction) point to compromised placental function.

• Ensure documentation explicitly states "placental insufficiency" or a similar term, and that the trimester is unspecified.
• Do not use this code if the affected fetus in a multiple gestation is clearly identified; instead, use a more specific code from the O36.51- series.
• Always sequence this code as a secondary diagnosis following the code for the primary reason for the encounter, if applicable.
