Walgreens won’t participate in future CVS Caremark Pharmacy network plans

Deerfield, Ill. Walgreens says it will no longer be a provider in new or renewed prescription drug plans awarded to CVS Caremark's pharmacy benefit manager.

Walgreens says CVS Caremark's promotion of some plan designs disrupts networks by requiring patients to use CVS Caremark services. Walgreens also cited the growing unpredictability of CVS Caremark's reimbursement rates among other reasons for ending the relationship.

Walgreens says current CVS Caremark plans in which it is already a pharmacy provider will not be affected.
