ICD10 code of Von Willebrand Disease and ICD9 code

The primary ICD-10-CM code for Von Willebrand Disease is D68.0, while the historical ICD-9-CM code is 286.4. These codes are utilized globally by healthcare systems to standardize the billing, tracking, and clinical documentation of this common inherited bleeding disorder.

What is the clinical significance of the ICD codes for Von Willebrand Disease?

In clinical practice, the classification of Von Willebrand Disease (VWD) is essential for ensuring patients receive appropriate care pathways and insurance coverage for necessary treatments like desmopressin or factor concentrates. While ICD-10 code D68.0 serves as the umbrella designation, clinicians often use specific sub-classifications to denote the severity and type of Von Willebrand Disease. Accurate coding is vital for the 184 members of our DiseaseMaps.org community and beyond, as it helps healthcare providers track the prevalence of the condition and ensures that medical records reflect the specific bleeding phenotype, which can range from mild bruising to severe, life-threatening hemorrhage.

How is Von Willebrand Disease classified?

Von Willebrand Disease is caused by a deficiency or dysfunction of the von Willebrand factor (VWF), a protein necessary for blood clotting. Because the clinical presentation varies significantly, medical professionals categorize the condition into three primary types:

• Type 1: The most common form, characterized by a partial quantitative deficiency of VWF (affects approximately 70-80% of patients).


• Type 2: Characterized by a qualitative defect in the VWF protein, subdivided into types 2A, 2B, 2M, and 2N.


• Type 3: The most severe form, involving a near-total absence of VWF, usually inherited in an autosomal recessive pattern.

Is Von Willebrand Disease hereditary?

Yes, Von Willebrand Disease is a genetic disorder. In most cases, it is inherited in an autosomal dominant pattern, meaning a child has a 50% chance of inheriting the mutation if one parent has it. However, Type 3 Von Willebrand Disease is typically inherited in an autosomal recessive manner, requiring both parents to carry the gene mutation. Genetic counseling is highly recommended for families navigating a diagnosis to understand the specific inheritance pattern and the potential risks for future generations.

How is a diagnosis of Von Willebrand Disease confirmed?

Diagnosis requires a combination of clinical history and specialized laboratory testing. Physicians typically look for a history of easy bruising, frequent nosebleeds, or prolonged bleeding after dental procedures. Diagnostic tests for Von Willebrand Disease include:

1. VWF antigen test to measure the total amount of VWF protein.


2. Ristocetin cofactor activity or VWF activity assay to test how well the protein functions.


3. Factor VIII clotting activity, as VWF acts as a carrier for Factor VIII.


4. Multimer analysis to determine the structural integrity of the VWF protein.

Next steps

• Consult a hematologist who specializes in bleeding disorders to confirm your specific type of Von Willebrand Disease.


• Maintain a "bleeding diary" to track episodes, which can assist your doctor in adjusting your management plan.


• Join the DiseaseMaps.org community to connect with other patients and caregivers who understand the daily challenges of managing this condition.


• Always inform your dentist and primary care physician of your diagnosis before undergoing any surgical or invasive medical procedures.
