CVS Caremark, Walmart clash over reimbursement rates

January 16, 2019 / Susan Morse

Walmart and its pharmacy benefit manager network, CVS Caremark, have fallen out over reimbursement rates, leaving commercial and managed Medicaid members out-of-network when filling scripts with the retailer. CVS Health said it has requested that Walmart continue to fill prescriptions as an in-network participating pharmacy through April 30. Medicare Part D beneficiaries remain in the network, as does Walmart's Sam's Club division. The clash is over reimbursement rates, with Walmart requesting increases, according to CVS Health, which did not give the financial terms.
