Let us help assist your employers in offering high-quality care at a reasonable cost. All third-party administrators (TPAs) are not the same. They may be Wisconsin-based, but can't offer large, true national networks or the deepest proprietary discounts. Only Anthem Blue Cross and Blue Shield (Anthem) offers both - a Wisconsin-based business that provides seamless access to trusted health care networks nationwide. Anthem is available for employers with 100 or more employees looking for self-funded products.
