Mat care chromsoml abnlt in fetus, Turner Syndrome, fetus 3

This code describes maternal care for a pregnancy where the fetus is suspected or confirmed to have Turner Syndrome, a chromosomal abnormality characterized by the absence of all or part of one X chromosome. This diagnosis is specific to the third fetus in a multiple gestation pregnancy.

Use this code when documentation indicates a pregnant patient is receiving care due to a suspected or confirmed diagnosis of Turner Syndrome in the third fetus. This typically follows abnormal prenatal screening results (e.g., NIPT, ultrasound findings) or definitive diagnostic testing like amniocentesis or chorionic villus sampling.

• Ensure documentation clearly specifies "fetus 3" for multiple gestations.
• Do not use this code for other chromosomal abnormalities; a more specific code within O35.1- should be selected.
• Assign additional codes for any associated maternal conditions or complications.
