QA0.8 ICD-10-CM Code: Other neurodevelopmental disorders related to pathogenic variants in other specific genes

QA0.8 is the ICD-10-CM diagnosis code for other neurodevelopmental disorders related to pathogenic variants in other specific genes. A developmental disorder affecting brain and nervous system function caused by genetic changes in genes not covered by other specific neurodevelopmental disorder categories. QA0.8 sits in the ICD-10-CM chapter for congenital malformations, deformations and chromosomal abnormalities (q00-qa0), within the section covering genetic disorders, not elsewhere classified (qa0).

QA0.8 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This is a catch-all code for rare genetic neurodevelopmental disorders; document the specific gene when possible.
