A66.0
BillableInitial lesions of yaws
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Yaws is a tropical infectious disease caused by bacteria, and this code represents the first skin lesions that appear when someone is initially infected. These early lesions typically appear as a single bump or sore at the site where the bacteria entered the body.
Coding Tips
- •Yaws (A66.0-A66.9) is endemic in tropical and subtropical regions; verify the patient's travel history or geographic origin to support medical necessity
- •This code represents the primary stage of yaws; if the disease has progressed to secondary or tertiary stages, use the appropriate A66 subcategory instead
