Summary
CareFirst is updating its commercial formulary effective October 1, 2026, to encourage use of safe and cost-effective medications. The billing team should review the formulary summary (available at the source URL) to understand which medications will be affected and adjust prior authorization, coverage, and patient counseling workflows accordingly.
Action Required
By September 15, 2026: Billing team must obtain and review the full Commercial Formulary Changes summary from CareFirst (linked in the policy). Identify which medications commonly prescribed by your practice are affected. Update billing system rules to reflect new coverage status, prior authorization requirements, or tier changes for affected drugs. Notify providers of formulary changes and update clinical staff on which medications may require prior authorization or patient cost-sharing changes effective October 1, 2026. Failure to implement changes may result in claim denials or delayed reimbursement for non-compliant prescriptions.
