Deletion from autosomes, unspecified

This code signifies a chromosomal abnormality characterized by the loss of genetic material from an autosome, where the specific chromosome or region involved in the deletion is not identified. It indicates a structural change in the chromosome complement that can lead to various developmental or health issues, but the precise genetic defect remains uncharacterized.

Apply this code when documentation confirms an autosomal deletion, but the specific location or type of deletion is not specified (e.g., "autosomal deletion found, further characterization pending" or "unspecified deletion on an autosome"). This code is appropriate for initial reports or when genetic testing is incomplete or inconclusive regarding the exact deletion site.

• Avoid using this code if a more specific autosomal deletion (e.g., 5p deletion, 22q11.2 deletion) is documented.
• Always query the provider for more specific genetic information if available to allow for more precise coding.
• Sequence this code as a primary diagnosis when the deletion is the reason for the encounter or a significant co-morbidity.
