Mat care chromsoml abnlt in fetus, Turner Syndrome, fetus 4

This code signifies ongoing maternal medical management and surveillance due to a suspected or confirmed diagnosis of Turner Syndrome in the fourth fetus of a multiple gestation pregnancy. Turner Syndrome is a chromosomal abnormality (monosomy X) affecting females, characterized by the absence of all or part of one X chromosome. Maternal care in this context focuses on monitoring fetal development and preparing for potential complications associated with the condition.

Apply this code when documentation indicates a pregnant patient is receiving care specifically because her fourth fetus has been identified with, or is highly suspected of having, Turner Syndrome. This typically follows prenatal diagnostic testing such as amniocentesis or chorionic villus sampling, or strong indicators from ultrasound findings. The medical record must clearly state the suspected or confirmed diagnosis of Turner Syndrome and specify the fetal order.

• Ensure the documentation explicitly identifies the fetus as the fourth in a multiple gestation.
• Do not use this code for a confirmed diagnosis of Turner Syndrome in the mother; it is specific to the fetus.
• Sequence this code as a primary diagnosis when the reason for the encounter is the maternal care related to the fetal condition.
