2025 ICD-10-CM code Q87.8

Other specified congenital malformation syndromes, not elsewhere classified.

Codes from Chapter 17, Congenital Malformations, Deformations, and Chromosomal Abnormalities (Q00-Q99), are not for use on the maternal record.When a congenital malformation is documented, it should be coded regardless of the patient's age.Use additional codes to identify associated manifestations.

Medical necessity for services related to Q87.8 is established by the presence of a congenital malformation syndrome affecting multiple body systems and the need for diagnostic evaluation, treatment, or management of associated health issues.The documentation should clearly link the services provided to the individual's specific manifestations and medical needs.

Clinical responsibility for diagnosing and managing Q87.8 typically falls on geneticists, pediatricians, and other specialists depending on the specific manifestations of the syndrome.This includes evaluating the patient's physical characteristics, ordering genetic testing if necessary, coordinating care with other specialists (e.g., cardiologists, orthopedists), and providing long-term follow-up.

In simple words: This code represents a group of congenital (present at birth) conditions that cause changes in multiple areas of the body and are not classified under other specific syndromes.These conditions arise from errors during fetal development, which may or may not be genetic.

Other specified congenital malformation syndromes affecting multiple systems, not elsewhere classified. Use additional code(s) to identify all associated manifestations.

Example 1: A newborn presents with multiple congenital anomalies, including cleft lip and palate, polydactyly (extra fingers or toes), and congenital heart disease. After extensive genetic and clinical evaluation, no specific syndrome is identified, and the diagnosis is categorized as Q87.8., A child is evaluated for developmental delays, unusual facial features, and skeletal abnormalities. Genetic testing and imaging studies are performed but do not reveal a known syndrome. The child's condition is classified as Q87.8, recognizing the multiple system involvement., An adult with a lifelong history of unexplained physical differences, such as abnormal joint mobility and skin irregularities, undergoes genetic testing. No specific genetic cause is identified, but the combination of abnormalities is consistent with Q87.8.

Documentation for Q87.8 should include detailed descriptions of all physical findings, results of genetic and diagnostic tests, and any relevant family history.Specific manifestations of the syndrome should be clearly documented, using appropriate clinical terminology.If a specific syndrome was considered but ruled out, the documentation should include an explanation for this decision.
