An Act relative to pharmacy benefit managers reimbursements to pharmacies in the Commonwealth

This bill amends Massachusetts law to regulate how pharmacy benefit managers determine reimbursement rates for pharmacies. It requires these managers to publish their pricing lists and update them within seven days if wholesale drug costs rise significantly. Additionally, the legislation establishes a formal appeal process allowing pharmacies to challenge reimbursement amounts that are too low or do not meet specific criteria. If a pharmacy successfully challenges a rate, the manager must adjust the pricing and allow the pharmacy to resubmit claims for affected prescriptions.
