US Part D Plan Choices in 2026

Across 15+ national insurers, Part D options varied widely in premiums, deductibles, coverage availability, and plan counts, making side-by-side comparison important for beneficiaries.
Across plans, monthly premiums ranged from $0 to >$150, while avg. annual deductibles ranged from ~$158 to ~$505, showing why total drug coverage matters.
When comparing plans, beneficiaries should weigh premiums, deductibles, coinsurance, formularies, prescription restrictions, pharmacy networks, preferred-pharmacy savings, and mail-order options for the right fit.
Plans can be joined through the federal plan finder, directly through an insurer, or with an agent, and coverage usually starts the following month.
In current 2026 rules, the Part D deductible rose to $615, the out-of-pocket cap reached $2.1K, and 10 negotiated drugs should see lower copays.
