What is ICD-10 code D68.029?

D68.029 is the ICD-10-CM diagnosis code for Von Willebrand disease, type 2, unspecified. A bleeding disorder caused by abnormal von Willebrand factor protein (type 2), but the specific subtype is not specified or documented. D68.029 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. D68.029 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. D68.029 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. D68.029 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does D68.029 map to under V28?

D68.029 maps to CMS-HCC V28 HCC 112 (Immune Thrombocytopenia and Specified Coagulation Defects and Hemorrhagic Conditions). The category numbers, labels, and conditions come from the CMS-HCC V28 model file for payment year 2026.

Buddy Documentation Tip

HCC Buddy guidance

Document VWF testing showing qualitative defect (disproportionate activity-to-antigen ratio), multimer analysis if available, and factor VIII levels.

Record current bleeding severity and treatment approach.

Query the provider to determine the specific subtype when additional testing has been performed.

MEAT Support

HCC Buddy guidance

Document VWF testing showing qualitative defect (disproportionate activity-to-antigen ratio), multimer analysis if available, and factor VIII levels.

Record current bleeding severity and treatment approach.

Query the provider to determine the specific subtype when additional testing has been performed.

Audit Caution

HCC Buddy guidance

This code should prompt a query to the provider for subtype specification, as treatment varies significantly between Type 2 subtypes (particularly regarding DDAVP use in Type 2B).

Do not use this code when specific Type 2 subtype documentation exists in the record.

Review hematology consultation notes for subtype-specific testing.

Common Mistakes

HCC Buddy guidance

D68.020-D68.023 (Specific Type 2 subtypes) — should be used when the subtype is documented

D68.00 (Von Willebrand disease, unspecified) — even more nonspecific and should be avoided when Type 2 is known

D68.01 (Type 1) — quantitative deficiency without the qualitative defect seen in Type 2.

Is D68.029 an HCC code?

Yes. D68.029 (Von Willebrand disease, type 2, unspecified) maps to HCC 112, Immune Thrombocytopenia and Specified Coagulation Defects and Hemorrhagic Conditions under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.450. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.

Coder answer: D68.029 is billable and maps to V28 HCC 112, Immune Thrombocytopenia and Specified Coagulation Defects and Hemorrhagic Conditions. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

Not separately weighted

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for D68.029

For D68.029, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.

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

What This Code Means

D68.029 is the ICD-10-CM diagnosis code for von willebrand disease, type 2, unspecified. A bleeding disorder caused by abnormal von Willebrand factor protein (type 2), but the specific subtype is not specified or documented. D68.029 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, D68.029 maps to Immune Thrombocytopenia and Specified Coagulation Defects and Hemorrhagic Conditions (HCC 112) with a source-labeled community, non-dual, aged reference coefficient of 0.450. No V24 mapping is shown for D68.029; use the applicable model and payment year when reviewing the V28 mapping. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.

Use this code only when type 2 is confirmed but the specific variant (2A, 2B, 2M, 2N) cannot be determined from documentation. For D68.029, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule. 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, source-labeled coefficient references, and MEAT documentation criteria for D68.029 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Use this code only when type 2 is confirmed but the specific variant (2A, 2B, 2M, 2N) cannot be determined from documentation
•Query the provider if additional testing results are available to specify the exact type 2 variant

Clinical Significance

Von Willebrand disease type 2, unspecified, captures cases where Type 2 VWD has been diagnosed through qualitative VWF defects but the specific subtype (2A, 2B, 2M, or 2N) has not been determined. Type 2 variants collectively account for approximately 20-25% of all VWD cases and generally present with more clinically significant bleeding than Type 1.

Documentation Requirements

✓Document VWF testing showing qualitative defect (disproportionate activity-to-antigen ratio), multimer analysis if available, and factor VIII levels.
✓Record current bleeding severity and treatment approach.
✓Query the provider to determine the specific subtype when additional testing has been performed.

Commonly Confused Codes

•D68.020-D68.023 (Specific Type 2 subtypes): should be used when the subtype is documented
•D68.00 (Von Willebrand disease, unspecified): even more nonspecific and should be avoided when Type 2 is known
•D68.01 (Type 1): quantitative deficiency without the qualitative defect seen in Type 2.
