AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2022 Quarter 4; New/Revised ICD-10-CM Codes
Von Willebrand Disease
The provider documented the patient has both Von Willebrand disease (VWD), type 1, and Factor VIII (functional) deficiency. ICD-10-CM classifies VWD, type 1, to code D68.01 , Von Willebrand disease, type 1, and Factor VIII deficiency to code D66 , Heredity factor VIII deficiency.
