Medicare Part D

Why Your Part D Drug Could Need New Approval in 2026

LUBBOCK, Texas — The envelopes are landing in South Plains mailboxes right now. If you have a Medicare Part D drug plan or a Medicare Advantage plan that includes drug coverage, your carrier is required to send an Annual Notice of Change (ANOC) each fall — and this year's version spells out what will look different starting January 1, 2027. A medication that was easy to fill all year can suddenly sit on a higher tier, require prior authorization, or come with a quantity limit. The rules of the program haven't changed, but the details inside each plan can — and Annual Enrollment (October 15 through December 7) is the window to react.

What the ANOC actually is

The Annual Notice of Change is a plain-language letter your plan is required to send before Annual Enrollment. It compares the 2026 plan design to the 2027 version — premium, deductible, drug list (called a formulary), pharmacy network, and any utilization management rules. If you take a regular prescription, the drug list section is the one to flag. Plans update these lists every year, and CMS reviews them, but the specific decisions about which drugs sit on which tier are made by the plan.

Tiers, in plain English

Most Part D plans sort covered drugs into tiers — usually five or six. Lower tiers generally include preferred generics; higher tiers include brand-name and specialty medications. The tier a drug lands on drives what you pay at the counter. When a drug shifts from, say, a preferred tier to a non-preferred tier for the new plan year, nothing about the drug has changed — only the plan's placement of it. That's why two neighbors in Lubbock County taking the same pill can pay very different amounts under different plans.

Prior authorization, step therapy, and quantity limits

These are the three most common "utilization management" tools, and any of them can appear or disappear on January 1.

• Prior authorization (PA): Your doctor has to send the plan clinical information before the prescription is approved.
• Step therapy: The plan asks you to try a lower-cost alternative first; if it doesn't work, you can move to the originally prescribed drug.
• Quantity limits: The plan caps how much of a drug it will cover in a given time period, usually based on FDA labeling.

None of these mean a drug is uncovered. They mean there's a paperwork step. If your ANOC shows a new rule on something you already take, call your prescriber's office early — waiting until January to start the conversation is how people end up at the pharmacy counter without their medicine.

The 2027 numbers that apply to everyone

A few Part D figures are set at the program level and apply no matter which plan you pick:

• The annual out-of-pocket cap is $2,400 in 2027 (up from $2,100 in 2026). Once your true out-of-pocket spending on covered drugs hits that number, you pay nothing for covered drugs for the rest of the calendar year.
• The maximum allowable deductible a Part D plan can charge is $700 in 2027 (it was $615 in 2026). Plans may charge less.
• The old "donut hole" coverage gap has been eliminated since 2025 — Part D now has three phases (deductible, initial coverage, catastrophic).
• The Medicare Prescription Payment Plan lets you spread your yearly drug costs across monthly payments to the plan instead of paying large amounts at the pharmacy. It's optional and has to be requested.
• IRMAA income-related surcharges on Part B and Part D begin above $109,000 for a single filer in 2026.

What to do if your drug moved

If a drug you take is changing tiers or picking up a new rule, you have real options:

1. Compare plans on Medicare.gov's Plan Finder. Enter your ZIP, your drug list, and your preferred pharmacy. It will show every stand-alone Part D and Medicare Advantage drug plan available in Lubbock County and estimate your yearly cost under each. 2. Ask your prescriber about alternatives that sit on a lower tier or have fewer restrictions. 3. Request an exception. If your doctor believes a preferred alternative won't work for you, the plan has a formal process to request that your drug be covered at a lower tier or that a rule be waived. 4. Use a transition fill. New members and continuing members whose drug is no longer covered are generally entitled to at least one 30-day transition supply early in the year, giving time to switch drugs or file an exception.

Deadlines Lubbock readers should circle

• October 15 – December 7: Annual Enrollment. Change your Part D or Medicare Advantage plan; changes take effect January 1.
• January 1 – March 31: Medicare Advantage Open Enrollment. If you're in a Medicare Advantage plan, you can make one change during this window.

Missing December 7 doesn't lock you out of everything, but it does mean you'll start January with whatever the ANOC described — new tiers, new rules and all.
