What these figures mean
Base premium: The amount shown is the plan's monthly base premium. Most Medicare enrollees also pay the standard Medicare Part B premium (generally deducted from your Social Security benefit). Higher-income enrollees pay an additional Income-Related Monthly Adjustment Amount (IRMAA). Low-income enrollees may qualify for the Extra Help (LIS) program, which can reduce or eliminate plan premiums and cost-sharing. A $0.00 plan premium does not mean $0 total monthly cost.
CMS star rating: CMS rates Medicare Advantage and Part D plans on a 1–5 star scale based on quality measures including preventive care, managing chronic conditions, member experience, and drug plan performance. A higher rating is generally better, but the best plan for you also depends on your specific prescriptions, preferred doctors and hospitals, and total cost-sharing. Star ratings reflect the contract's performance across its full service area — not Dewey specifically.
MOOP (Maximum Out-of-Pocket): For MA plans, the Maximum Out-of-Pocket limit caps your annual in-network cost-sharing. Not shown in the table above; visible at medicare.gov/plan-compare for each specific plan.
