Neurodevelopmental disorders related to specific genetic pathogenic variants (QA0) ICD-10-CM
The QA0 code range covers neurodevelopmental disorders related to specific genetic pathogenic variants with 20 ICD-10-CM diagnosis codes. 13 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
