Part D, phase by phase
Part D is Medicare's prescription-drug coverage, and you can get it either on its own alongside Original Medicare or baked into a Medicare Advantage plan. The government sets the structure; private insurers run the plans.
Here's the shape of a 2027 plan: you first pay a deductible (capped at $700), then share costs during initial coverage, and finally hit a catastrophic phase where a new yearly out-of-pocket cap kicks in — the old coverage gap has been eliminated. If lumpy pharmacy bills are a worry, the Medicare Prescription Payment Plan can spread them monthly.
We explain how all of that plays out in Gilbert, Arizona. Because each plan's drug list and pricing differ, the plan-specific details belong on Medicare's Plan Finder — we don't rank plans.
Prescription coverage
How Medicare Part D works in 2027
The old coverage gap (“donut hole”) is eliminated as of 2025 (three phases now). There’s now a hard yearly cap of $2,400 on what you pay out of pocket for covered drugs, and you can spread those costs across the year with the Medicare Prescription Payment Plan.

How the 2027 Part D drug cap works
Slide to your estimated yearly prescription costs and see how the $2,400 out-of-pocket cap protects you. This illustrates the standard Part D benefit; your plan may structure costs differently.
Once your out-of-pocket spending on covered drugs reaches $2,400, you pay nothing more for the rest of 2027. Confirm details at Medicare.gov.

Find your 2026 Medicare premium
Most people pay the standard Part B premium. If your 2024 income was higher, an income-related surcharge (IRMAA) applies. Enter your details to see your bracket.
Surcharges are added to your premiums and based on your 2024 tax return. Married-filing-separately uses a different schedule. Confirm at Medicare.gov.

What Medicare costs in 2027
It helps to separate the costs everyone shares from the costs that vary by plan. The program-level numbers here are set nationally — the same whether you're in a big city or a rural county.
Part B premium. Most people pay the standard Part B premium of $202.90 a month in 2026 (2026 amount; 2027 figure will be posted when CMS releases it). Part A is premium-free for most people who worked and paid Medicare taxes long enough.
Part D drug costs. In 2027, a Part D plan's yearly deductible can be no more than $700, and a $2,400 cap limits what you pay out of pocket for covered prescriptions across the year — a real change for anyone with high drug costs.
Higher earners pay more for Parts B and D through an income-related adjustment called IRMAA, which for 2026 starts above $109,000 in annual income for an individual and is based on your 2024 tax return. Most people fall below that line and pay the standard amounts. The 2027 brackets will be posted when CMS releases them.
Plan-specific costs. What an individual plan charges — its premium, deductible, copays, and what it covers — varies by plan and changes yearly. We don't publish those figures or rank plans; Medicare's Plan Finder shows the current details for your situation, and a licensed agent can walk you through them.
By the numbers
Medicare Part B premium, 2006–2026

Your Medicare enrollment calendar
The dates that follow are set federally, so they don't change from state to state — only your personal timing does.
It starts with your Initial Enrollment Period — the 7-month window around your 65th birthday month — the window around turning 65 when you first sign up. Missing it can mean late penalties that stick around, so it's the one not to sleep on.
After that, the big recurring window is the Annual Enrollment Period, October 15 – December 7, when anyone can join, switch, or drop an Advantage or Part D plan for a January 1 start. And if you're already in an Advantage plan, the Medicare Advantage Open Enrollment (January 1 – March 31) gives you one more chance to change course.
Life events — a move, a loss of other coverage — can also trigger a Special Enrollment Period. The calendar below shows the whole year at a glance.
