Antepartum hemorrhage with afibrinogenemia, unsp trimester

This code signifies bleeding from the uterus during pregnancy, specifically when the patient also experiences afibrinogenemia, a rare blood clotting disorder characterized by the absence or severe deficiency of fibrinogen. This condition can lead to severe and uncontrolled hemorrhage. The "unspecified trimester" indicates that the exact gestational age at the time of the hemorrhage is not documented.

Assign this code when documentation clearly indicates antepartum hemorrhage in a pregnant patient diagnosed with afibrinogenemia, and the specific trimester of pregnancy is not recorded. This scenario often arises in emergency settings or when initial documentation lacks precise gestational details.

• Ensure documentation explicitly states both "antepartum hemorrhage" and "afibrinogenemia."
• If the trimester is specified, a more precise code from the O46.01- series should be used (e.g., O46.011 for first trimester).
• Sequence this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if the hemorrhage is a complication of another primary condition.
