Trisomy 18 and Trisomy 13
Chapter 17:Congenital malformations and chromosomal abnormalities
ICD-10 Q91 is a used to indicate a diagnosis of trisomy 18 and trisomy 13.
The ICD-10 Level 1 Category code Q91 encompasses conditions related to Trisomy 18 and Trisomy 13, both of which are chromosomal disorders resulting from the presence of an extra chromosome 18 or 13, respectively. These conditions are characterized by severe developmental delays, congenital anomalies, and a high rate of mortality in infancy. Trisomy 18, also known as Edwards syndrome, is associated with a range of physical abnormalities including low birth weight, heart defects, and organ malformations. Trisomy 13, or Patau syndrome, presents with similar challenges, including cleft lip and palate, polydactyly, and neurological impairments. The clinical significance of these conditions lies in their profound impact on the affected individuals and their families, necessitating comprehensive medical care and support.

Q91 includes Trisomy 18 (Edwards syndrome) and Trisomy 13 (Patau syndrome), both of which are characterized by the presence of an extra chromosome leading to significant developmental and physical challenges.
Q91 codes should be used when diagnosing patients with confirmed Trisomy 18 or Trisomy 13, particularly when there are associated congenital anomalies or developmental delays that require specialized medical attention.
Documentation for Q91 should include genetic testing results confirming the diagnosis of Trisomy 18 or Trisomy 13, detailed clinical findings, and any associated conditions or anomalies observed in the patient.
