HCC Category Mapping

What This Code Means

A bleeding disorder caused by circulating antibodies or inhibitors that interfere with blood clotting factors, other than those specified in related codes.

Coding Tips

• •Document the specific type of inhibitor or anticoagulant present (such as inhibitors to factors other than VIII, or other circulating anticoagulants)
• •Use this code when the hemorrhagic disorder is due to intrinsic anticoagulants not captured by D68.311 or D68.312

Clinical Significance

This code captures hemorrhagic disorders due to intrinsic circulating anticoagulants, antibodies, or inhibitors other than acquired hemophilia (factor VIII inhibitors) or antiphospholipid-related hemorrhage. This includes rare acquired inhibitors against factors V, IX, X, XI, XIII, or von Willebrand factor, which can cause serious and sometimes fatal bleeding.

Documentation Requirements

• ✓Document the specific factor or protein targeted by the acquired inhibitor, inhibitor titer level, mixing study results showing failure to correct, and any associated underlying condition (autoimmune disease, malignancy, medication).
• ✓Record the treatment strategy for both acute bleeding management and inhibitor eradication.
