Mat care chromsoml abnlt in fetus, Turner Syndrome, fetus 2

This code signifies specialized maternal care provided when a 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 particular code specifies that the diagnosis pertains to the second fetus in a multiple gestation pregnancy.

Use this code when a pregnant patient is receiving antenatal care due to a prenatal diagnosis or strong suspicion of Turner Syndrome in one of the fetuses, specifically the second one. Documentation should clearly indicate the suspected or confirmed diagnosis of Turner Syndrome and specify its occurrence in fetus 2, often identified through genetic testing like amniocentesis or chorionic villus sampling, or detailed ultrasound findings.

• Ensure documentation explicitly identifies the affected fetus as "fetus 2" in a multiple gestation.
• Do not confuse with codes for other chromosomal abnormalities; this code is specific to Turner Syndrome.
• Always sequence this code as a secondary diagnosis following the appropriate code for the pregnancy, such as O09.- for supervision of high-risk pregnancy.
