D68.01 is a billable ICD-10-CM diagnosis code for von Willebrand disease, type 1. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 813. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 50 closely related codes. Coders also document this condition as hereditary von Willebrand disease. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Coagulation and hemorrhagic disorders.
For Medicare Advantage risk adjustment, D68.01 maps to CMS-HCC Category 112 (Immune Thrombocytopenia and Specified Coagulation Defects and Hemorrhagic Conditions) under the V28 model, adding a risk factor of about 0.450 for a community, non-dual, aged beneficiary in payment year 2027.

Patient EducationClinical
Platelet Disorders
Platelets, also known as thrombocytes, are blood cells. They form in your bone marrow, a sponge-like tissue in your bones. Platelets play a major role in blood clotting. Normally, when one of your blood vessels is injured, you start to bleed.

Questions About D68.01Overview
What is the ICD-10 code for von Willebrand disease, type 1?
The ICD-10-CM code for von Willebrand disease, type 1 is D68.01 (sometimes written as D6801). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is D68.01 (Von Willebrand disease) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report von Willebrand disease, type 1 on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does D68.01 group to?
When von Willebrand disease, type 1 is the principal diagnosis on an inpatient stay, it groups to MS-DRG 813 (coagulation Disorders), which carries a relative weight of 1.5279. Higher weights mean higher Medicare reimbursement.
Is D68.01 a CC or MCC?
CMS lists D68.01 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 50 closely related codes in its exclusion list.
Can D68.01 be reported with D69.8?
Not as a rule. The Excludes1 note at D68.0, which applies to D68.01, lists "capillary fragility (hereditary) (D69.8)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What HCC is D68.01?
D68.01 (von Willebrand disease, type 1) maps to CMS-HCC Category 112 (Immune Thrombocytopenia and Specified Coagulation Defects and Hemorrhagic Conditions), commonly written as HCC 112, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 48 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.
Does D68.01 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, D68.01 adds a risk adjustment factor of about 0.450 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.450 to 0.708 depending on the payment segment). A more severe related category (HCC 111) supersedes it when both are reported. See the full factor table on the HCC 112 category page.
