Mat care cnsl malf/damag fts, spina bifida, fetus 4

This code signifies ongoing maternal medical management and monitoring due to a confirmed or suspected diagnosis of spina bifida in the fourth fetus of a multiple gestation pregnancy. It indicates that the mother is receiving specialized care because of this specific fetal central nervous system anomaly.

Use this code when documentation clearly indicates maternal care for a fetus diagnosed with, or suspected of having, spina bifida, and the pregnancy involves quadruplets where the affected fetus is identified as the fourth. This typically applies to high-risk obstetric encounters, consultations with maternal-fetal medicine specialists, or during prenatal diagnostic procedures.

• Ensure the medical record explicitly identifies the affected fetus as the "fourth" in a multiple gestation.
• Do not use this code for other types of fetal CNS malformations; a more specific O35 subcategory would be appropriate.
• Always sequence this code as a secondary diagnosis following the code for the type of encounter (e.g., routine prenatal visit, high-risk pregnancy supervision).
