Mat care cnsl malf/damag fts, choroid plexus cysts, unsp

This code signifies maternal care provided due to the presence or suspicion of choroid plexus cysts in the fetus. These cysts are fluid-filled structures within the choroid plexus of the brain, often detected during prenatal ultrasound. While frequently benign and resolving spontaneously, they can sometimes be associated with chromosomal abnormalities.

Use this code when a pregnant patient receives monitoring, counseling, or further diagnostic testing specifically because a fetal choroid plexus cyst has been identified or is suspected. Documentation should clearly indicate the maternal care is directly related to the fetal choroid plexus cyst, rather than other fetal anomalies.

• Ensure the documentation specifies "choroid plexus cysts" and not other types of fetal CNS malformations, which have different codes.
• This code is for maternal care due to the fetal condition; it is not used to code the fetal condition itself.
• Always sequence this code as a secondary diagnosis following the appropriate code for the maternal condition or reason for encounter.
