Drug store chain Walgreens Inc. says it will stop filling prescriptions for members of Midwest Health Plan July 1 because of “inadequate” pharmacy reimbursement rates.

Walgreens, Deerfield, Ill., says its discussions with Midwest Health Plan for several months failed to reach agreement on a reimbursement rate for the costs of medication and processing insurance claims.

The company is continuing to talk to Midwest, Dearborn, Mich., and hopes to rejoin its plan in the future, said Chris Whelan, Walgreens’ vice president of store operations.

Walgreens has 5,251 stores in 45 states and Puerto Rico.
