Patau's syndrome

This code represents Patau's syndrome, also known as Trisomy 13, a severe chromosomal disorder characterized by the presence of an extra copy of chromosome 13. It typically results in multiple congenital anomalies affecting various organ systems, including the brain, heart, kidneys, and facial structures. Infants with this condition often experience significant developmental delays and have a very poor prognosis.

Use this code when documentation confirms a diagnosis of Patau's syndrome, typically identified through genetic testing such as karyotyping. This code is appropriate for newborns or infants diagnosed with the characteristic clinical features and confirmed chromosomal abnormality. Supporting documentation should include genetic test results or a definitive clinical diagnosis by a geneticist or pediatrician.

• Ensure genetic testing results or a clear clinical diagnosis of Trisomy 13 are present in the medical record.
• Do not confuse with other trisomies (e.g., Trisomy 18 - Edwards' syndrome, Trisomy 21 - Down syndrome), which have distinct ICD-9-CM codes.
• Code all associated congenital anomalies and manifestations of Patau's syndrome as secondary diagnoses.
