D68.09
BillableOther von Willebrand disease
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is D68.09 an HCC code?
Yes. D68.09 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 D68.09
For D68.09 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 D68.09 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
D68.09 is the ICD-10-CM diagnosis code for other von willebrand disease. A bleeding disorder related to von Willebrand factor that does not fit into the standard type 1, 2, or 3 classifications. D68.09 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, D68.09 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, D68.09 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.
Use this code for atypical presentations or variants of von Willebrand disease not captured by more specific codes. Because D68.09 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 D68.09 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code for atypical presentations or variants of von Willebrand disease not captured by more specific codes
- •Document the specific characteristics or test results that led to this diagnosis to justify the use of the unspecified category
Clinical Significance
This code captures other specified forms of von Willebrand disease that do not fit into Types 1, 2, or 3 categories, including atypical presentations or mixed phenotypes. It may also be used for provisionally diagnosed VWD where complete subtyping has not yet been performed but certain features exclude the standard types.
Documentation Requirements
- ✓Document all VWF testing performed including antigen, activity, multimer analysis, and factor VIII levels.
- ✓Explain why the presentation does not fit standard types and what specific features distinguish this variant.
- ✓Record genetic testing results if available and the current treatment approach.
