Acquired coagulation factor deficiency

This code represents a bleeding disorder resulting from a deficiency in one or more coagulation factors that is not congenital but rather develops after birth. This deficiency impairs the body's ability to form clots, leading to increased bleeding tendencies. It can be caused by various underlying conditions affecting factor production or increasing factor consumption.

Use this code when documentation indicates a patient has a coagulation factor deficiency that is acquired, such as vitamin K deficiency, liver disease, disseminated intravascular coagulation (DIC), or the presence of circulating anticoagulants. Supporting documentation should specify the acquired nature of the deficiency and often includes laboratory findings of prolonged PT, PTT, or specific factor assays.

• Differentiate carefully between acquired and congenital factor deficiencies; congenital deficiencies are classified elsewhere.
• Always code the underlying cause of the acquired deficiency (e.g., liver disease, vitamin K deficiency) first, if known and applicable.
• Do not use for deficiencies due to therapeutic anticoagulation, unless a true deficiency is also present.
