Prem separtn of placenta w afibrinogenemia, third trimester

This code signifies the premature detachment of the placenta from the uterine wall occurring during the third trimester of pregnancy, specifically complicated by afibrinogenemia. Afibrinogenemia is a rare blood clotting disorder characterized by the absence or severe deficiency of fibrinogen, a crucial protein for blood coagulation. This combination presents a high risk of severe hemorrhage for both mother and fetus.

Apply this code when documentation clearly indicates a diagnosis of placental abruption in a pregnant patient in her third trimester, alongside a confirmed diagnosis of afibrinogenemia. This would typically be supported by laboratory findings showing absent or extremely low fibrinogen levels in conjunction with clinical signs and symptoms of placental separation.

• Ensure documentation specifies "third trimester" for accurate code assignment.
• Verify that afibrinogenemia is explicitly diagnosed, not just suspected coagulopathy.
• Sequence this code as a principal diagnosis when it is the primary reason for the encounter, followed by codes for any associated complications.
