Medicare Part D

Lafayette, LA: The $2,400 Part D Cap for 2027

Starting January 1, 2027, Medicare Part D will cap what you pay out of pocket for covered prescriptions at $2,400 for the year. Once you hit that number, you pay nothing more for the rest of 2027 on covered drugs at the pharmacy counter. For Lafayette residents choosing coverage during the Annual Enrollment Period, which runs through December 7, this is the biggest change to pay attention to — and it changes the math on how you compare plans.

Lafayette, La. — A hard ceiling on drug costs arrives in January

The cap is set by Medicare itself. It applies to every Part D plan and every Medicare Advantage plan that includes drug coverage, no matter which carrier you pick.

What actually changed, in plain English

Part D used to have four phases, including the confusing "donut hole" coverage gap where your share of drug costs jumped. That gap was eliminated in 2025. For 2027, Part D has three simpler phases:

• Deductible phase. Plans can charge a deductible up to a maximum of $615 in 2026 and $700 in 2027. Some plans charge less; none can charge more.
• Initial coverage phase. You pay a share (a copay or coinsurance) for each prescription.
• Catastrophic phase. Once your out-of-pocket spending on covered drugs reaches $2,400 for the year in 2027, you pay nothing more for covered drugs for the rest of the calendar year.

The $2,400 counter resets every January 1. Premiums you pay for the plan itself do not count toward the cap — only what you spend on covered prescriptions does.

The Medicare Prescription Payment Plan: smoothing the bill

If you take an expensive medication, hitting that cap early in the year can still mean a painful January or February. That's why Medicare offers the Medicare Prescription Payment Plan, an optional program that lets you spread your out-of-pocket drug costs across the calendar year in monthly payments instead of paying the full amount at the pharmacy.

A few things worth knowing:

• It's optional and free to opt into. You don't save money overall — you still owe what you owe — but the timing of payments changes.
• You sign up through your Part D or Medicare Advantage drug plan, not through Medicare directly.
• It tends to help people with high drug costs early in the year. If your prescriptions are inexpensive, it may not be useful.
• You can opt in at any time during the year, not just during AEP.

Plan availability in the Lafayette area

Lafayette is in Lafayette Parish, and plan availability is set at the parish (county) level. That means every Medicare-eligible resident with a Lafayette Parish address sees the same menu of Part D and Medicare Advantage plans, regardless of which neighborhood they live in. The specific number of plans and carriers offered in Lafayette Parish for 2027 is listed in each plan's Annual Notice of Change and on Medicare's Plan Finder at medicare.gov/plan-compare, where you can enter your ZIP code and your prescription list to see how each plan handles your drugs.

Higher-income filers: watch the IRMAA line

If your modified adjusted gross income was above $109,000 as a single filer (or $218,000 for a couple filing jointly) on your most recent tax return used by Social Security, you'll pay an Income-Related Monthly Adjustment Amount (IRMAA) on top of your Part B and Part D premiums in 2026. The cap ($2,100 in 2026, $2,400 in 2027) still applies to you — IRMAA is a premium surcharge, not a change to your out-of-pocket drug ceiling.

Key deadlines to circle
