Medicare Annual Enrollment Starts This Week: A Guide to Reviewing Your 2027 Coverage in Arizona
October 15 marks the official start of Medicare’s Annual Enrollment Period (AEP), running through December 7, 2026. This annual window allows beneficiaries to make adjustments to their Medicare Advantage and prescription drug coverage for the upcoming calendar year, with any changes taking effect on January 1, 2027.
A common question during this season is whether people who already like their coverage need to take action.
Staying with your existing plan is often a sensible decision. However, even if you are satisfied with your current plan, plan details can adjust from one year to the next. Taking time for a focused review helps you check whether your coverage will continue to align with your health needs and budget for 2027.
What Does the Annual Enrollment Period Cover?
The Annual Enrollment Period is specifically designed for reviewing and modifying Medicare Advantage (Part C) and Part D prescription drug coverage. It is not an open window for every insurance product, nor is it the period for individuals initially enrolling in Medicare Part A and Part B.
Between October 15 and December 7, you can:
Switch from Original Medicare to a Medicare Advantage plan.
Switch from a Medicare Advantage plan back to Original Medicare.
Note on Medigap underwriting: Dropping Medicare Advantage to return to Original Medicare does not automatically grant you the right to purchase a Medicare Supplement insurance policy (Medigap) without medical underwriting. Outside of your initial Medigap open enrollment window or specific federal guaranteed-issue protections, private insurers may evaluate your medical history, charge higher premiums or deny coverage.
Switch from one Medicare Advantage plan to another.
Join, switch or drop a standalone Medicare Part D prescription drug plan if you have Original Medicare. Most Medicare Advantage plans bundle medical and prescription drug coverage together into an all-in-one plan.
Note on Part D late-enrollment penalties: If you choose to drop Part D coverage, going 63 or more consecutive days without Medicare drug coverage or other creditable prescription coverage can result in a permanent Part D late-enrollment penalty if you decide to re-enroll in the future.
Why Review Your Plan Even If You Are Satisfied?
Insurance carriers can adjust plan terms, provider networks and cost sharing annually. Here are the key areas to evaluate:
1. Prescription Drug Formularies and the 2027 Drug Spending Cap
A formulary is your plan's approved list of covered medications. Carriers can update their formularies each fall, reassigning medications to different cost tiers, changing flat copays to percentage coinsurance or adding prior-authorization criteria.
For the 2027 plan year, covered Part D prescription drug out-of-pocket costs are capped at $2,400. This cap is a meaningful benchmark for prescription spending, though it applies strictly to covered Part D drugs. This does not include plan premiums or drugs your plan does not cover. Additionally, the maximum Part D deductible set by Medicare for 2027 is $700; keep in mind this is an annual statutory ceiling rather than an amount charged by every plan.
Preferred pharmacy networks can also change. Checking whether your local retail pharmacy remains a preferred network location helps you understand your out-of-pocket costs before filling prescriptions in January.
2. Healthcare Provider and Facility Networks
Medicare Advantage plans rely on specific networks of doctors, specialists, clinics and hospitals. Physician groups and regional health systems throughout Maricopa County and Arizona periodically update their provider agreements. Verifying that your primary physician, specialists and preferred hospitals remain contracted for 2027 helps identify potential network disruptions before you choose your coverage.
3. Monthly Plan Premiums, Medical Out-of-Pocket Limits and Plan Costs
Costs can shift across multiple categories. In addition to reviewing copays and coinsurance, check your monthly plan premium for both medical and standalone drug coverage.
Medicare Advantage plans also feature an annual maximum out-of-pocket (MOOP) limit for covered medical services (such as hospital stays, doctor visits and diagnostic tests). This medical limit is separate from the Part D prescription drug cap. Reviewing both medical limits and monthly premiums helps you understand your total anticipated costs for the coming year.
4. Supplemental Benefits
Many Medicare Advantage plans include additional benefits, such as allowances for dental, vision, hearing care, fitness memberships or over-the-counter health items. Carriers can adjust benefit allowances, copays or vendor partnerships annually. Reviewing your plan documents helps confirm whether the extra perks you use will remain available in the same form.
Understanding Your Annual Notice of Change (ANOC)
During September, you should have received an Annual Notice of Change (ANOC) from your current plan carrier. If you did not receive your ANOC, contact your plan. This document summarizes key changes to your plan’s coverage, costs and service rules for the upcoming year.
While the ANOC is a helpful starting point, it is a summary. It is best used alongside detailed 2027 plan documents, 2027 formularies and 2027 provider directories to confirm your specific medications and doctors.
Preparing for Your Coverage Review: A Practical Checklist
Reviewing your coverage is straightforward when you have the right information ready. Before sitting down to evaluate options, gather:
Your medication details: Write down exact medication names (brand or generic), exact dosages and strengths, quantities per refill and your preferred pharmacy.
Your healthcare providers: Note the names, specialty practices and clinic locations of your primary doctor, specialists and preferred hospital.
Your current plan premiums and cost records: Note what you currently pay each month in plan premiums for medical and prescription drug coverage.
Anticipated healthcare needs: Consider any planned procedures, diagnostic tests or ongoing therapies you anticipate in 2027.
Your Annual Notice of Change: Keep the summary booklet you received in September accessible.
Your insurance cards: Have your red, white and blue Medicare card and your current plan membership card on hand.
