Z36.8A ICD-10-CM Code: Encounter for antenatal screening for other genetic defects

Z36.8A is the ICD-10-CM diagnosis code for encounter for antenatal screening for other genetic defects. A prenatal screening visit where tests are performed to check for genetic defects in the baby, such as cystic fibrosis or sickle cell disease. Z36.8A sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons encountering health services in circumstances related to reproduction (z30-z39).

Z36.8A 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 genetic condition(s) being screened for and the testing method used (carrier screening, NIPT, etc.).
