What This Code Means
Z3A.14 is the ICD-10-CM diagnosis code for 14 weeks gestation of pregnancy. A code indicating the pregnancy has progressed to 14 weeks of gestation, now in the second trimester. Z3A.14 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).
Z3A.14 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.
Second trimester screening tests are now appropriate; document any screening offered or performed.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z3A.14 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
