ICD-10 Code D68.023 – Von Willebrand disease, type 2N (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D68.023 – Von Willebrand disease, type 2N
What it is
D68.023 identifies type 2N von Willebrand disease, a subtype with reduced binding of von Willebrand factor to factor VIII. Use it when documentation specifically names this inherited bleeding disorder subtype.
Clinical signs
Clinical features vary; refer to documentation. Common findings include mucocutaneous bleeding, easy bruising, heavy menstrual bleeding, and bleeding after procedures, with some patients showing low factor VIII activity.
When to use this code
Use this code when the provider documents type 2N von Willebrand disease, including “2N,” “Normandy variant,” or equivalent wording. It also fits confirmed hereditary von Willebrand disease with specific factor VIII-binding defect noted in the record.
Check documentation if the note only says von Willebrand disease without subtype. If the chart describes another bleeding disorder, coagulopathy, or acquired factor deficiency, choose the more specific documented diagnosis.
Do not use for
Do not use D68.023 for other von Willebrand subtypes, such as type 1, 2A, 2B, 2M, or 3. Also avoid it when the diagnosis is unconfirmed or not specified as type 2N.
Coding tip
Code the exact subtype named by the clinician; if type 2N is not clearly documented, query for clarification before assigning D68.023.
