Supporters say the bill is designed to curb vertical integration, restore fair competition, and protect independent pharmacies from reimbursement practices they view as harmful to patient access and community pharmacy survival.

CVS has pushed back hard, warning that the new law could force it to shut down its 134 Tennessee pharmacy locations and trigger a legal challenge. The company argues the measure would reduce access for patients and does not directly address broader PBM issues like pricing or formularies.

This Tennessee fight reflects a larger national battle over PBM reform, pharmacy ownership, market power, and the future of prescription drug access.
