A letter from your Medicare plan arrives in September, and it looks like another routine insurance document. You set it aside, assuming your coverage will remain the same next year. But that envelope may contain some of the most financially important information you’ll receive before Medicare Open Enrollment ends.
The Annual Notice of Change, commonly called the ANOC, explains how your existing Medicare Advantage or Part D prescription drug plan will change for the following year. Here are five details worth reviewing before the December 7 enrollment deadline.
1. Changes to Your Monthly Premium
One of the first numbers to examine is your plan’s monthly premium for 2027. A plan that charged little or nothing in additional premiums during 2026 may have a different price next year. However, a lower premium doesn’t necessarily mean the plan will be less expensive overall.
Deductibles, copayments, coinsurance, and coverage restrictions can have a greater financial impact depending on your healthcare needs. You should compare the total expected annual cost rather than deciding whether to stay enrolled based on the premium alone.
Suppose your Medicare Advantage plan’s additional monthly premium increases from $20 to $45. That $25 difference represents $300 in additional annual expenses before accounting for other plan changes. If prescription copayments and specialist visit costs also rise, the combined increase could be considerably larger. On the other hand, a higher-premium plan may sometimes offer lower costs for services you use frequently.
Ultimately, the most important question is how the entire plan fits your expected healthcare spending rather than whether one individual number increased.
2. Your Prescription Drug Deductible and Copayments
Prescription drug costs deserve particular attention because the standard Medicare Part D deductible is increasing in 2027. The maximum permitted Part D deductible rises from $615 in 2026 to $700 in 2027, although individual plans may charge less. The official Medicare drug cost information explains that premiums, deductibles, copayments, and coinsurance vary by plan. A medication that was inexpensive this year may cost more if its coverage tier or cost-sharing arrangement changes.
For 2027, Medicare establishes a $2,400 annual out-of-pocket threshold for covered Part D drugs. Once a beneficiary reaches the applicable threshold, covered Part D drugs generally enter the catastrophic coverage stage with no additional cost sharing for those drugs. However, premiums and expenses for drugs not covered by Part D generally don’t count toward that threshold. Certain payments made on a beneficiary’s behalf may count under Medicare’s rules, making the calculation more complicated than simply adding pharmacy receipts. The Medicare Part D cost explanation provides additional details about the coverage stages.
Review your complete medication list rather than assuming last year’s prescription prices will continue.
3. Changes to Your Doctors and Healthcare Network
For Medicare Advantage beneficiaries, provider access can be just as important as monthly costs. A plan may change its network arrangements, meaning a physician or hospital that participated previously may no longer be available under the same terms. The Annual Notice of Change can alert beneficiaries to certain coverage changes, but it shouldn’t be treated as a complete current provider directory. Contact your insurer and healthcare providers to verify participation in the specific 2027 plan.
Suppose you are a retiree who regularly sees a cardiologist for an ongoing medical condition. If that physician is no longer in the plan’s network, the retiree may face higher costs or need to find another participating specialist. The larger financial impact depends on the type of Medicare Advantage plan, its out-of-network rules, and the circumstances of the care. Some plans provide limited out-of-network coverage, while others generally require beneficiaries to use network providers except in specified situations.
Ask about referrals, prior authorization requirements, and whether any planned procedures could be affected by changes in coverage. And always verify your options before scheduling expensive treatment or assuming that a familiar physician will remain covered.
4. Changes to Dental, Vision, and Other Extra Benefits
Supplemental benefits are frequently promoted as a major advantage of Medicare Advantage coverage. Dental, vision, hearing, transportation, and other benefits can be useful, but the details may change annually. A plan may alter benefit allowances, participating providers, eligible services, or cost-sharing requirements. An advertised dental allowance doesn’t necessarily mean every procedure will be covered up to that amount without restrictions.
Suppose a Medicare Advantage plan advertises $2,000 in annual dental benefits. That amount may sound sufficient to cover extensive dental work, but actual coverage depends on the plan’s rules. Certain procedures may be excluded, require prior authorization, or involve substantial coinsurance. Network limitations can also affect which dentists will accept the coverage.
Before choosing a plan because of its dental benefits, ask how it would cover the specific services you’re likely to need. Always review the plan’s Evidence of Coverage to understand the actual benefit limits before relying on promotional descriptions.
5. Your Maximum Out-of-Pocket Medical Costs
Medicare Advantage plans establish annual out-of-pocket limits for covered Part A and Part B services, subject to Medicare requirements. These limits can differ between plans and may change from one year to the next. The maximum generally doesn’t include every healthcare expense, such as monthly premiums or covered Part D prescription drug costs. A plan with lower routine copayments may still expose beneficiaries to substantial expenses during a year involving hospitalization or frequent specialist visits.
A retiree who rarely visits the doctor may focus primarily on premiums and routine copayments. But an unexpected hospitalization, surgery, or serious illness can quickly change the financial calculation. A plan’s out-of-pocket maximum establishes an important limit for applicable covered medical services, although the exact protections depend on the plan and whether services are in-network. Compare that limit with the amount you could realistically afford to pay from savings.
The right coverage decision should account for both ordinary healthcare expenses and the possibility of a financially difficult year. Make sure you double-check the medical out-of-pocket maximum alongside deductibles, hospital costs, and other cost-sharing requirements.
FAQs About Medicare’s ANOC
Navigating anything to do with Medicare can feel like a headache. Here are some frequently asked questions about Medicare’s Annual Notice of Change.
- What if you never received your Annual Notice of Change? Medicare plans generally send the Annual Notice of Change in September before the following year’s enrollment decisions. If you haven’t received the document, contact your plan and request another copy. It’s possible that you may also be able to access plan documents through your insurer’s member portal. Just because you haven’t received an ANOC doesn’t mean your coverage will remain the same.
- What if your plan is being discontinued? An Annual Notice of Change isn’t the same as a formal notice that a plan is ending. Beneficiaries whose plans will no longer be offered may receive separate nonrenewal notices explaining their coverage options and applicable deadlines. Plans ending for 2027 generally had to provide nonrenewal notices by October 2, 2026. Some beneficiaries may qualify for special enrollment rights depending on why their coverage is ending.
- What do I do if my plan is being discontinued? If your plan is being discontinued, review the notice carefully and contact Medicare or a qualified counselor for help understanding your options.
- What is the difference between an ANOC and Evidence of Coverage? The ANOC is designed to highlight important changes, but it doesn’t necessarily provide every detail needed to compare coverage. The Evidence of Coverage offers more extensive information about benefits, restrictions, and cost sharing.
