Wal-Mart is expanding a pilot program that eliminates copays on generic drugs purchased at its stores to more employers.
The program already operates at the construction company Caterpillar, where employees who purchase generic prescription drugs at a Wal-Mart or Sam’s Club pharmacy are waived the $5 copayment. Some see the program as a way to help employers reduce health care costs tied to prescription drugs by trimming the work they have to do pharmacy benefit managers.
