BillableAntepartum hemorrhage with afibrinogenemia, second trimester
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Bleeding during the second trimester of pregnancy caused by afibrinogenemia, a condition where the body lacks the ability to produce fibrinogen needed for blood clotting.
Coding Tips
- •Document that afibrinogenemia is the confirmed diagnosis, not just a suspected coagulation defect
- •Second trimester spans weeks 14-20; confirm this in the clinical documentation
