Neurodev dis, rel to oth genes assoc w txn & gene expression

This code identifies a neurodevelopmental disorder stemming from genetic mutations affecting genes involved in transcription and gene expression. These disorders typically present with a range of developmental delays, intellectual disability, and often distinctive physical features or neurological symptoms, varying based on the specific gene affected.

Apply this code when documentation explicitly links a patient's neurodevelopmental disorder to a genetic anomaly impacting transcription or gene expression, as confirmed by genetic testing. This is appropriate for cases where the specific gene is identified but does not have a more precise ICD-10-CM code.

• Ensure genetic testing results clearly state a pathogenic variant in a gene related to transcription or gene expression.
• Do not use this code if a more specific ICD-10-CM code exists for the identified genetic syndrome.
• Always sequence this code as the primary diagnosis when it is the underlying cause of the patient's presenting symptoms.
