What This Code Means
QA0.0139 is the ICD-10-CM diagnosis code for neurodevelopmental disorder, related to pathogenic variant in other transporter or solute carrier gene. A neurodevelopmental disorder caused by mutations in transporter or solute carrier genes other than SLC6A1, affecting how nutrients and neurotransmitters move across cell membranes. QA0.0139 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).
QA0.0139 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 transporter or solute carrier gene involved in the clinical record.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for QA0.0139 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the specific transporter or solute carrier gene involved in the clinical record
- •Use this code when the gene is identified but does not match other specific transporter categories
