Lawyers at Boies Schiller Flexner, including antitrust heavyweight William Isaacson, have hit a group of Anthem-owned insurance companies with a lawsuit claiming they illegally dropped a California pharmacy from their network of prescription drug providers.

CZ Services Inc., a Richmond-based company owned by former Sun Microsystems CEO Jonathan Schwartz which does business as CareZone Pharmacy, leaned on the Boies Schiller lawyers to sue Anthem Insurance Companies Inc., Blue Cross and Blue Shield of Kansas City, and Premera Blue Cross. The lawsuit, filed Thursday in the U.S. District Court for the Northern District of California, claims that the insurers’ pharmacy benefits manager Express Scripts Inc., which is not named as a defendant in the suit, terminated CareZone from participating in the insurers’ “pharmacy network plan” in violation of state laws in California and Tennessee.

A spokeswoman for Anthem said Friday that the company would not comment on the lawsuit.

CareZone claims that the Anthem companies, as principals in Express Scripts, can be held liable for its actions in cutting the pharmacy out of prescription drug plans, which the pharmacy claims Express Scripts did on their behalf. Express Scripts, CareZone’s lawyers contend, has indicated that it will not work with mail-order pharmacies which might compete with its own mail-order business. CareZone claims the insurers now violate the “any willing provider” provisions of the Medicare Part D Act and Social Security Act, which forces companies to permit pharmacies that serve Medicare Part D and Medicaid prescription drug benefits that meet certain criteria participate in their networks.

The lawsuit claims that CareZone’s exclusion violates both California’s Unfair Competition Law and Tennesee’s “Any Willing Provider” Statute. The suit asks for a finding that the insurers, through Express Scripts, have improperly terminated CareZone from their networks and an injunction barring the company from denying participation to the pharmacy going forward. The suit also seeks an undisclosed amount of restitution as well as court costs and attorney fees.

Boies Schiller’s Isaacson was out of the office Friday and didn’t immediately respond to a message seeking comment.
