Is QA0.012 an HCC code?
No. QA0.012 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.

What This Code Means
QA0.012 is the ICD-10-CM diagnosis code for neurodevelopmental disorders, related to pathogenic variants in other receptor genes. A developmental disorder caused by mutations in receptor genes other than glutamate receptors, affecting how brain cells communicate. QA0.012 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).
QA0.012 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.
Document the specific receptor gene type in the medical record for reference.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for QA0.012 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the specific receptor gene type in the medical record for reference
- •Use when receptor gene mutations are identified but do not fall under glutamate receptor category
