Other deletions from the autosomes

This code signifies a genetic condition characterized by the absence of a segment of chromosomal material from an autosome, excluding those specifically classified elsewhere. These deletions can lead to a wide spectrum of developmental, intellectual, and physical abnormalities depending on the size and location of the deleted region.

Use this code when genetic testing confirms a pathogenic deletion on an autosome that is not otherwise specified by a more precise ICD-10-CM code. This applies to patients presenting with congenital anomalies, developmental delay, or intellectual disability where a chromosomal microdeletion is identified. Documentation should clearly state the presence of an autosomal deletion and rule out more specific syndromes.

• Ensure the deletion is from an autosome (chromosomes 1-22) and not a sex chromosome.
• Always search for a more specific code first if the deletion is associated with a named syndrome or a precisely defined chromosomal region.
• Documentation must explicitly state "autosomal deletion" and ideally include the specific chromosome and band if known, even if a more specific code isn't available.
