Matern care for disproprtn d/t unusually large fetus, fts4

This code signifies maternal care provided when the size of the fetus is unusually large, creating a disproportion that complicates the pregnancy. Specifically, it indicates that the fourth fetus in a multiple gestation pregnancy is the one identified as unusually large. This condition can lead to difficulties during labor and delivery.

Use this code when documentation clearly indicates maternal care for disproportion due to an unusually large fetus, and the specific fetus identified is the fourth in a multiple gestation. This typically applies to pregnancies with triplets, quadruplets, or higher-order multiples. Supporting documentation would include ultrasound reports detailing fetal biometry, physician notes indicating macrosomia or large for gestational age (LGA) for the fourth fetus, and a clinical assessment of cephalopelvic disproportion (CPD) or risk thereof.

• Ensure the medical record explicitly identifies the fourth fetus as unusually large and causing disproportion.
• Do not confuse this with codes for other fetal presentations or positions, or codes for disproportion due to maternal pelvic abnormalities.
• Always sequence this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis if it complicates another primary obstetric condition.
