Multiple congenital malformations, not elsewhere classified

This code signifies the presence of several birth defects affecting multiple body systems that do not fit into a specific, recognized congenital syndrome. It is used when a patient presents with a combination of anomalies that are not clearly linked to a named genetic disorder or chromosomal abnormality.

Apply this code when documentation indicates multiple congenital anomalies without a definitive diagnosis of a specific syndrome. This is appropriate when the physician has identified several distinct malformations but has not categorized them under a code from the Q87.- series. Supporting documentation would include detailed descriptions of each malformation.

• Ensure the documentation explicitly states "multiple congenital malformations" and does not point to a specific syndrome.
• Review the "Excludes1" note carefully; never code this with Q87.- codes.
• Code all individual congenital anomalies present in addition to this code, if known and documented.
