Acquired coagulation factor deficiency

This code signifies a bleeding disorder resulting from a reduction in the functional activity or quantity of one or more coagulation factors, which is not congenital. This deficiency develops after birth and can lead to impaired hemostasis and increased bleeding risk.

Assign this code when documentation indicates a patient has an acquired deficiency of a clotting factor, such as Factor VIII inhibitor (acquired hemophilia A), acquired von Willebrand disease, or other acquired factor deficiencies. This code is appropriate when the cause is not a congenital genetic defect.

• Do not use this code for congenital factor deficiencies; those are classified elsewhere (e.g., D66, D67, D68.0-D68.2).
• Ensure documentation clearly states the deficiency is "acquired" to differentiate from hereditary forms.
• Code any underlying cause of the acquired deficiency (e.g., liver disease, autoimmune conditions) as an additional diagnosis.
