D65: ICD10 Code for Disseminated intravascular coagulation [defibrination syndrome]

D65 refers to Disseminated intravascular coagulation [defibrination syndrome], a group of bleeding and coagulation disorders caused by genetic mutations, systemic illnesses, or acquired factors. These conditions affect the body’s ability to form clots properly, leading to excessive bleeding, bruising, or in some cases, dangerous thrombosis.

Symptoms

• Easy bruising – Common in hereditary clotting disorders
• Prolonged bleeding – Especially after injury or surgery
• Spontaneous bleeding – In joints (hemarthrosis), nosebleeds, or gums
• Purpura or petechiae – Small purple skin spots from capillary bleeding
• Heavy menstrual bleeding – A common symptom in female carriers
• Internal bleeding – Can occur in severe cases or with DIC
• Fatigue or dizziness – If blood loss is significant

Diagnosis

Diagnosis of Disseminated intravascular coagulation [defibrination syndrome] includes coagulation panel (PT, aPTT, INR), factor assays (for VIII, IX deficiencies), D-dimer and fibrinogen levels (for DIC), platelet count, and genetic testing. Accurate diagnosis helps determine the severity and appropriate management strategy.

ICD10 Code Usage

ICD10 code D65 is used by hematologists, internists, emergency physicians, and surgeons to document bleeding disorders. These codes support insurance reimbursement, hemophilia treatment registry reporting, and clinical decision-making for acute and chronic management.

Related Codes

• D66 – Hereditary factor VIII deficiency
• D67 – Hereditary factor IX deficiency
• D68 – Other coagulation defects
• D69 – Purpura and other hemorrhagic conditions

FAQs

Q1: What is ICD10 code D65?
A: It refers to Disseminated intravascular coagulation [defibrination syndrome], a bleeding or coagulation disorder used for medical documentation and billing.

Q2: Are these conditions genetic or acquired?
A: Some (e.g., D66, D67) are inherited, while others (e.g., D65, D68) can be acquired or secondary to illness.

Q3: Are they curable?
A: Genetic conditions are not curable but can be managed with factor replacement therapy. Acquired conditions depend on treating the underlying cause.

Q4: What is the treatment?
A: Clotting factor infusions, antifibrinolytics, plasma transfusion, immunosuppressants, or managing the triggering condition.

Q5: Who manages these disorders?
A: Hematologists usually lead care, with involvement from emergency and surgical teams when bleeding complications arise.

Conclusion

ICD10 code D65 plays a vital role in identifying and managing Disseminated intravascular coagulation [defibrination syndrome]. Accurate coding ensures prompt treatment, helps coordinate specialized care, and supports tracking outcomes for bleeding and coagulation disorders.
