    ICD-10-CM Code For Disseminated Intravascular Coagulation Defibrination Syndrome: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group D65 includes disseminated intravascular coagulation, a systemic coagulopathy characterized by widespread activation of clotting and secondary bleeding that can result from sepsis, trauma, malignancy, or obstetric complications. These ICD-10-CM diagnosis codes are used to document acute coagulation derangements, capture disease severity, and indicate multi-organ involvement or bleeding risk that impacts treatment decisions. Accurate coding within the ICD-10-CM D65 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM D65: Disseminated Intravascular Coagulation [Defibrination Syndrome] Overview

    This group represents disseminated intravascular coagulation, a systemic disorder of coagulation leading to simultaneous thrombosis and bleeding that affects multiple organs. It targets the hematologic system and can complicate severe infections, trauma, malignancy, or obstetric conditions. Accurate coding is important for reflecting clinical complexity and ensuring appropriate reimbursement and care tracking.

    When to Use

    Use a code from this group when a patient has a clinical diagnosis of disseminated intravascular coagulation documented by the treating clinician. Codes are appropriate when DIC is contributing to bleeding, thrombosis, or organ dysfunction and is part of the clinical problem list or encounter diagnosis.

    Typical Clinical Scenarios

    • A middle-aged patient presents to the emergency department with sudden onset of widespread bleeding (epistaxis, bleeding from IV sites, and hematuria) and signs of shock after severe sepsis from a urinary tract infection. Laboratory studies show prolonged coagulation times, low platelets, elevated D-dimer, and schistocytes on peripheral smear, indicating systemic activation of coagulation. A diagnosis from this group is assigned for the acute consumptive coagulopathy causing life‑threatening hemorrhage and thrombosis. Typical codes: D65
    • An obstetric patient is admitted postpartum with retained placental tissue and develops heavy vaginal bleeding, hypotension, and multi‑organ dysfunction; labs reveal falling fibrinogen and rising fibrin degradation products consistent with consumptive coagulopathy. The patient requires transfusion support and critical care for the acute postpartum coagulopathy, leading clinicians to assign a code from this group. Typical codes: D65
    • An inpatient with acute promyelocytic leukemia receiving induction chemotherapy develops progressive bleeding, oozing from catheter sites, and laboratory evidence of widespread clot formation with thrombocytopenia and elevated D‑dimer. Because the patient’s bleeding and laboratory profile reflect systemic intravascular clotting and fibrin consumption as a complication of malignancy and its treatment, a code from this group is used. Typical codes: D65
