Mat care chromosomal abnlt in fetus, Turner Syndrome, unsp

This code signifies ongoing maternal care due to a confirmed or suspected diagnosis of Turner Syndrome in the fetus. Turner Syndrome is a chromosomal abnormality (monosomy X) affecting females, characterized by the absence of all or part of one X chromosome. This code is used when the maternal care is specifically for managing the pregnancy in light of this fetal condition.

Use this code when the pregnant patient is receiving care because the fetus has been diagnosed with, or is suspected of having, Turner Syndrome. Documentation should clearly indicate the fetal diagnosis (e.g., from amniocentesis, chorionic villus sampling, or detailed ultrasound findings) and that maternal care is being provided in relation to this finding.

• This code is for maternal care due to the fetal condition, not for the fetal condition itself.
• Requires an additional code from category Z3A to specify the weeks of gestation.
• Do not use if the chromosomal abnormality is definitively identified as something other than Turner Syndrome; use the appropriate O35.1- subcategory.
