You’ll get an Annual Notice of Change (ANOC) by September 30 if you’re in a Medicare Advantage or Part D plan. Review it to spot next year’s premiums, copays, deductibles, provider network changes, and drug formulary updates. Plans run Jan 1–Dec 31 and auto-renew Jan 1, so use the Oct 15–Dec 7 Annual Enrollment Period to switch if costs or coverage worsen. Check tier shifts, coinsurance changes, and out-of-pocket limits to avoid surprises. Here’s how to make smart moves.
Learning Highlights
- Expect an ANOC by September 30 if you’re in Medicare Advantage or Part D; it outlines next year’s premiums, benefits, networks, and drug formulary changes.
- Compare current and upcoming premiums, deductibles, copays/coinsurance, and out-of-pocket maximums to spot cost increases.
- Verify provider and pharmacy networks to avoid out-of-network charges or reduced convenience.
- Review the drug formulary for coverage, tier changes, and shifts from copays to coinsurance that affect medication costs.
- Use AEP (Oct 15–Dec 7) to switch plans; otherwise, your plan auto-renews January 1 with the new terms.
Why the Annual Notice of Change Matters and Key Deadlines
Even if your coverage felt fine this year, the Annual Notice of Change (ANOC) is your early warning system for next year’s premiums, benefits, formularies, and plan availability.
Read it to spot shifts in costs, drug tiers, deductibles, and network rules before they hit January 1. Plans operate on a one-year calendar, so ignoring ANOC can lock you into auto-renewal with worse terms.
You must receive ANOC by September 30. Use it to prepare for the Annual Enrollment Period, October 15–December 7.
Compare premiums, coverage limits, formularies, and out-of-pocket caps. If you don’t receive it on time, contact your plan immediately for a copy.
Who Receives an ANOC and What to Expect
Not everyone gets an ANOC. You’ll receive one if you’re enrolled in a Medicare Advantage plan or a standalone Part D drug plan, because these plans change yearly.
If you have only Medicare Parts A and B, or a Medigap policy, you won’t get an ANOC; those aren’t annual plans. Premium changes for A and B arrive separately.
Expect a summary of next year’s premiums, copays, deductibles, network changes, and drug formulary updates, including tier shifts or new coinsurance.
Review pharmacy and provider listings closely. If your ANOC hasn’t arrived by September 30, contact your plan for a copy so you can evaluate upcoming changes.
How Plan Years, Auto-Renewals, and AEP Work Together
Because Medicare Advantage and Part D plans run on a strict calendar year (January 1–December 31), your current plan will auto-renew on January 1 unless you make a change during the Annual Enrollment Period (AEP), October 15–December 7.
Auto-renewal keeps coverage continuous, but it may lock in terms you don’t want next year. Use AEP to align your plan with your needs for the coming year.
- Watch for your ANOC by September 30 so you’re ready to compare.
- Mark AEP dates on your calendar and set reminders.
- Confirm prescriptions, doctors, and benefits still fit.
- If satisfied, do nothing and allow auto-renewal.
Reading Changes to Premiums, Coverage, Networks, and Costs
Ready to spot what’s different for next year? Start with premiums. Compare last year’s monthly premium to the new amount, and note any added plan or Part B givebacks.
Next, check medical coverage: inpatient, outpatient, preventive, and extras like dental, vision, and hearing—look for benefit caps and prior authorization changes.
Review provider networks. Confirm your doctors, hospitals, and pharmacies remain in-network; out-of-network costs can spike.
Then scan cost-sharing: deductibles, copays, coinsurance, emergency/urgent care, ambulance, and the annual out-of-pocket maximum—both in- and out-of-network.
Finally, confirm plan availability and service area. If your plan exits, prepare to choose a replacement.
Formularies, Tiers, and Drug Cost Shifts You Need to Watch
As you review your ANOC, zero in on the drug formulary: it’s the plan’s list of covered medications, organized by tiers that drive what you’ll pay. Confirm every prescription remains covered and note any tier shifts.
Tier 1–2 drugs often have low copays; tiers 3–5 can include coinsurance that spikes costs, especially if a drug moves up a tier.
- Check each medication’s tier and any new prior authorization or step therapy.
- See if a flat copay changed to percentage coinsurance.
- Compare preferred vs. standard pharmacies for lower prices.
- Ask about therapeutic alternatives if your drug moves or drops.
Out-of-Pocket Maximums, Deductibles, and Financial Impact
Even when your premium stays the same, the real budget hit often comes from your out-of-pocket maximum and deductibles.
Check your ANOC to see if your in-network MOOP is moving toward $4,000–$6,000 and whether out-of-network caps jump to $7,000–$12,000. These reset January 1, so a late-year diagnosis can spill costs into next year.
Verify medical and Part D deductibles. The Part D deductible rises from $590 to $615; tier 1–2 drugs may bypass it, but tiers 3–5 usually won’t.
Note any new coinsurance replacing copays. Model worst-case costs to see if your savings justify potential exposure.
Making Coverage Decisions During AEP and When to Seek Help
So how do you turn your ANOC into a smart AEP decision? Start by matching next year’s premiums, formularies, and provider networks to your needs.
Check tier changes and deductibles, especially if your drugs moved to coinsurance. Verify your doctors and pharmacies stay in-network and your hospital is covered. If your plan’s being discontinued, shortlist replacements before October 15.
- Review meds: confirm tiers, prior auth, and step therapy.
- Compare annual costs: premiums + copays + MOOP.
- Ensure care access: network, referrals, travel coverage.
- Note deadlines and proof: save ANOC and confirmations.

Frequently Asked Questions
How Do I Request ANOC Materials in Accessible Formats or Languages?
Ask your plan’s customer service to send ANOC in large print, Braille, audio, or your language. If needed, call 1-800-MEDICARE and request free translation. Like a lighthouse, accessible formats guide your coverage decisions.
What Should I Do if My ANOC Contains Errors?
Report errors to your plan immediately, request a corrected ANOC, and document your call. Ask for written confirmation, escalate to a supervisor if needed, and contact 1‑800‑MEDICARE or your State Health Insurance Assistance Program for guidance and appeal support.
How Can Caregivers Legally Access and Review a Beneficiary’s ANOC?
Obtain written authorization or a HIPAA-compliant release, or secure a Medicare Authorization to Disclose form. You can also use a durable power of attorney or become a representative payee. Then contact the plan to receive and review ANOC.
Will Travel Plans Affect How I Interpret ANOC Network Changes?
Yes. You’ll weigh network changes against your travel patterns. Check if your Medicare Advantage plan’s network, out-of-network costs, and pharmacy access cover destinations. Consider PPO vs HMO flexibility, snowbird coverage, travel benefits, and nationwide formularies before AEP decisions.
How Do I Compare ANOCS From Multiple Plans Side-By-Side Efficiently?
Create a checklist: premiums, deductibles, MOOP, drug deductible, tier changes, formulary counts, key meds’ tiers, pharmacy network, provider network, benefits removed/added, referrals. Use each plan’s Evidence of Coverage/ANOC tables, highlight differences, then model your annual costs with your medications and visits.
