Matern care for oth or susp poor fetl grth, third tri, fts1

This code signifies maternal care provided due to concerns about a single fetus experiencing suboptimal growth during the third trimester of pregnancy. It indicates that the healthcare provider is actively monitoring or managing a known or suspected issue with the fetus's development and size.

Apply this code when documentation indicates maternal care for a singleton pregnancy in the third trimester where the fetus is identified with or suspected of having poor growth, but not specifically intrauterine growth restriction (IUGR). This code is supported by documentation of fetal growth assessments (e.g., ultrasound measurements, fundal height) showing a fetus below expected growth parameters for gestational age, requiring ongoing maternal management.

• Ensure the documentation specifies "third trimester" and "fetus 1" for accurate application.
• Distinguish from O36.51- (maternal care for suspected poor fetal growth, unspecified trimester) and O36.59- (other known or suspected poor fetal growth, unspecified trimester).
• This code is for maternal care related to the fetal condition; the fetal condition itself (e.g., P05.1-) would be coded separately if applicable.
