What is the principal ICD-10-CM code assigned for a patient with von Willebrand's disease after a plasma transfusion?

• A. D68.00
• B. I21.09
• C. C61
• D. E11.621

Answer: (A)

The principal ICD-10-CM code assigned for a patient with von Willebrand's disease is D68.00, which specifically refers to von Willebrand's disease without bleeding. Von Willebrand's disease is a genetic bleeding disorder caused by a deficiency or dysfunction of von Willebrand factor, which is necessary for proper blood clotting.

When assigning an ICD-10-CM code, it's important to select a code that accurately reflects the patient's condition. Option D68.00 directly correlates with von Willebrand's disease and identifies it appropriately within the classification system. This makes it the most suitable choice, as it captures the primary diagnosis rather than any additional conditions or complications that may or may not be present.

The other options pertain to different conditions or situations that are not directly related to von Willebrand's disease. For example, I21.09 corresponds to an unspecified acute myocardial infarction, C61 is a code for prostate cancer, and E11.621 refers to a type of diabetes mellitus with foot complications. Since these codes serve entirely different medical contexts, they would not be appropriate for a patient diagnosed with von Willebrand's disease undergoing treatment.
