Walmart drops CVS pharmacy coverage in price dispute

Walmart said Tuesday that it would no longer honor prescription drug coverage from CVS Health, leaving large numbers of Walmart customers searching for a new pharmacist and amplifying concerns about the growing market power of the CVS empire. Walmart confirmed its exit from the CVS Health pharmacy insurance program, called CVS Caremark, after CVS refused the retail giant’s demand for larger reimbursements for the prescription drugs it dispenses.
