How Does Medicare Part D Work in Oklahoma?

Understand how Medicare Part D covers prescriptions in Oklahoma, including costs and formularies.

Prescription drugs are one of the biggest healthcare costs in retirement. Medicare Part D provides drug coverage, but plans vary widely in Oklahoma. Choosing the right plan can save you thousands per year.

How Part D Works

Part D is offered by private insurers approved by Medicare. Plans cover prescriptions but differ in premiums, formularies (drug lists), and pharmacy networks.

Costs to Expect

• Premiums: $10–$70/month depending on plan
• Deductible: Up to $545 in 2025
• Copays/Coinsurance: Varies by drug tier

Coverage Stages

1. Initial coverage: Copays apply until spending reaches the limit.
2. Coverage gap (“donut hole”): Costs may increase temporarily.
3. Catastrophic coverage: Lower copays after out-of-pocket maximum.
