Maternal care for hereditary disease in fetus, fetus 1

This code describes a pregnant patient receiving medical care due to a concern or suspicion that her fetus (specifically, fetus 1 in a multiple gestation) may have a hereditary disease. This care involves monitoring, diagnostic testing, or counseling related to the potential genetic condition.

Use this code when documentation indicates maternal care is provided because of a family history of a genetic disorder, abnormal genetic screening results, or other clinical indicators suggesting a hereditary disease in the first fetus. Supporting documentation includes genetic counseling notes, prenatal diagnostic test orders (e.g., amniocentesis, CVS, NIPT), and physician notes detailing the suspected hereditary condition.

• Always assign an additional code from Chapter 17 (Q00-Q99) to specify the suspected hereditary disease, if known.
• Ensure the documentation clearly identifies the concern as related to a hereditary disease, not just a congenital anomaly.
• Verify laterality or specific fetal identification (e.g., fetus 1, fetus 2) in multiple gestations.
