BOSTON (AP) — Two big-box retail companies will pay Massachusetts towns and cities $232,000 for allegedly overcharging public agencies for prescription drugs through the worker’s compensation insurance system.

Attorney General Martha Coakley announced the settlement with Wal-Mart Stores Inc. and Target Corp. on Tuesday.

The settlement was filed in Suffolk Superior Court Monday. Under the terms of the deal, Bentonville, Ark.-based Wal-Mart will pay $207,000. Minneapolis-based Target will cover the remaining $25,000. The retail chains are now required to put in place measures to prevent future overcharges.

Cities and towns that were overcharged by the two retailers include Amherst, Boston, Concord, Everett, Fall River, Framingham, Hingham, Lowell, Plymouth, Springfield and Worcester.

The Attorney General’s office has recovered more than $8 million through similar investigations of pharmacy chains and other pharmaceuticals retailers.
