Matern care for disproprtn due to hydrocephalic fetus, fts3

This code signifies maternal care provided when the size of a hydrocephalic fetus creates a disproportion with the mother's pelvis, making a vaginal delivery difficult or impossible. It specifically indicates that this is the third fetus in a multiple gestation pregnancy.

Apply this code when documentation clearly states maternal care for cephalopelvic disproportion (CPD) caused by fetal hydrocephalus, and the pregnancy involves triplets or more, with this being the third fetus. This diagnosis is typically made during late pregnancy or labor when the fetal head circumference is significantly enlarged due to hydrocephalus, preventing engagement or descent through the birth canal.

• Ensure documentation specifies "hydrocephalic fetus" as the cause of disproportion, not other fetal anomalies.
• Verify the fetal number (3) is explicitly documented for accurate specificity in multiple gestations.
• Consider sequencing this code as a primary diagnosis when the disproportion is the main reason for admission or intervention, followed by codes for the fetal condition (e.g., Q03.9 for unspecified hydrocephalus).
