D68.023
BillableVon Willebrand disease, type 2N
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is D68.023 an HCC code?
Yes. D68.023 maps to Von Willebrand Disease and Other Coagulation Defects under the CMS-HCC V28 risk adjustment model (and Coagulation Defects and Other Specified Hematological Disorders under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for D68.023
For D68.023 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed D68.023 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
D68.023 is the ICD-10-CM diagnosis code for von willebrand disease, type 2n. Von Willebrand disease type 2N is a bleeding disorder where the body produces abnormal von Willebrand factor protein that doesn't work properly, causing difficulty with blood clotting and increased bleeding tendency. This specific type involves a defect in how the von Willebrand factor binds to platelets. D68.023 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering coagulation defects, purpura and other hemorrhagic conditions (d65-d69).
Under the CMS-HCC V28 risk adjustment model, D68.023 maps to Von Willebrand Disease and Other Coagulation Defects (HCC 112) with a community, non-dual, aged base RAF weight of 0.247. Under the older CMS-HCC V24 model, D68.023 maps to Coagulation Defects and Other Specified Hematological Disorders (HCC 48) with a community, non-dual, aged base RAF weight of 0.209. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Verify the specific type of von Willebrand disease (type 1, 2A, 2B, 2M, 2N, or 3) is documented in the medical record before assigning this code, as each type has a distinct ICD-10-CM code. Because D68.023 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D68.023 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify the specific type of von Willebrand disease (type 1, 2A, 2B, 2M, 2N, or 3) is documented in the medical record before assigning this code, as each type has a distinct ICD-10-CM code
- •This code may be used alongside procedure codes for von Willebrand factor testing or treatment codes (such as desmopressin administration) depending on the clinical encounter
Clinical Significance
Von Willebrand disease type 2N (Normandy variant) is characterized by markedly reduced VWF binding affinity for factor VIII, resulting in accelerated factor VIII clearance and low factor VIII levels. This variant mimics mild Hemophilia A and may be misdiagnosed as such. Autosomal recessive inheritance distinguishes it from X-linked Hemophilia A.
Documentation Requirements
- ✓Document VWF:factor VIII binding assay results showing reduced binding capacity, low factor VIII levels with relatively normal VWF antigen and activity, and genetic testing confirming the Type 2N mutation.
- ✓Record family history noting autosomal recessive inheritance pattern and any prior Hemophilia A diagnosis that should be revised.
