Disseminated intravascular coagulation [defibrination syndrome] (D65) ICD-10-CM
The D65 code range covers disseminated intravascular coagulation [defibrination syndrome] with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Afibrinogenemia, acquired
- Consumption coagulopathy
- COVID-19 associated diffuse or disseminated intravascular coagulopathy
- Diffuse or disseminated intravascular coagulation [DIC]
- Fibrinolytic hemorrhage, acquired
- Fibrinolytic purpura
- Purpura fulminans
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- , if applicable, associated condition
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the D65 range.
Afibrinogenemia
A deficiency or absence of FIBRINOGEN in the blood.
Disseminated Intravascular Coagulation
A disorder characterized by procoagulant substances entering the general circulation causing a systemic thrombotic process. The activation of the clotting mechanism may arise from any of a number of disorders. A majority of the patients manifest skin lesions, sometimes leading to PURPURA FULMINANS.
Fibrinogen
Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
Purpura Fulminans
A severe, rapidly fatal reaction occurring most commonly in children following an infectious illness. It is characterized by large, rapidly spreading skin hemorrhages, fever, or shock. Purpura fulminans often accompanies or is triggered by DISSEMINATED INTRAVASCULAR COAGULATION.
Waterhouse-Friderichsen Syndrome
A condition of HEMORRHAGE and NECROSIS of the ADRENAL GLAND. It is characterized by rapidly developing ADRENAL INSUFFICIENCY; HYPOTENSION; and widespread cutaneous PURPURA.
About the D65 Code Range
ICD-10 code D65disseminated intravascular coagulation (DIC), also known as defibrination syndrome. This condition involves abnormal clotting throughout the blood vessels leading to serious bleeding issues.
The ICD-10 code for disseminated intravascular coagulation covers a range of related conditions characterized by excessive fibrinolysis or clot breakdown. Common synonyms include systemic fibrinogenolysis, hyperfibrinolysis, and purpura fulminans. It also applies to drug-induced fibrinolytic disorders caused by agents like urokinase or tissue plasminogen activator. This code helps medical coders document complex coagulation and hemorrhagic disorders such as acquired fibrinogen abnormalities or consumption coagulopathy from snake venom. Correctly using code D65 ensures accurate classification of this serious disorder, which disrupts normal clot formation and leads to both clotting and severe bleeding problems.
