Disseminated intravascular coagulation

This code represents a severe, life-threatening disorder characterized by widespread activation of the coagulation system, leading to the formation of microthrombi throughout the body. This process consumes clotting factors and platelets, ultimately resulting in paradoxical bleeding. It is also known as defibrination syndrome due to the depletion of fibrinogen.

Use this code when documentation clearly indicates a diagnosis of disseminated intravascular coagulation (DIC) as a primary or secondary condition. This typically occurs in the context of severe underlying conditions such as sepsis, trauma, malignancy, or obstetric complications. Supporting documentation should include laboratory findings consistent with DIC (e.g., elevated D-dimer, prolonged PT/aPTT, thrombocytopenia, decreased fibrinogen).

• Always review the "Excludes1" notes carefully to avoid incorrect co-coding with obstetric or newborn-related DIC.
• Code the underlying cause of DIC first, if known, as DIC is often a complication of another severe condition.
• Ensure documentation specifies "disseminated intravascular coagulation" or "defibrination syndrome" to support this code.
