Colorado Medicare members can prepare for 2027 Annual Enrollment by gathering their Annual Notice of Change, prescription list, provider names, and current plan documents before October 15. Annual Enrollment runs October 15 through December 7. Elections take effect January 1, 2027. Compare official 2027 plans once they appear.
This practical checklist complements our Colorado Medicare guide. It focuses on preparation, while our article about the Medicare Annual Enrollment Period explains what coverage changes the window allows.
What should you do before October 15?
Start with a clean list of what matters to you. Gather your current plan card, Annual Notice of Change, prescriptions with doses, preferred pharmacies, doctors, specialists, and hospitals. Write down expected care for the coming year. This creates one reliable worksheet for comparing 2027 plans once official details are available.
Do not rely only on last year's plan. Benefits, drug lists, provider networks, and cost sharing can change. As of September 30, 2026, 2027 details are being released. Use official plan materials and Medicare.gov when the new information appears.
How do you read the Annual Notice of Change?
The Annual Notice of Change shows how an existing Medicare Advantage or Part D plan will differ next year. Plans send it by the end of September. Review changes to benefits, cost sharing, drug coverage, pharmacy rules, service areas, and provider access before deciding to stay or switch.
Mark every change that affects a service or medication you use. If a section is unclear, write down the question and confirm it with the plan or a licensed broker. Keep the notice beside the current Evidence of Coverage so you can compare the language.
What belongs on your 2027 review checklist?
A complete review brings plan information and personal information together. The table below gives a practical order. Gather the documents now, then use them when 2027 comparison information appears. Never estimate a new plan's costs or benefits from an advertisement.
| Step | What to gather | Where to find it |
|---|---|---|
| 1. Review plan changes | Annual Notice of Change and current plan card | Mail or member portal from the current plan |
| 2. List prescriptions | Drug name, dose, frequency, and preferred pharmacy | Prescription labels, pharmacy account, or clinician list |
| 3. Confirm providers | Doctors, specialists, hospitals, and clinics | Personal records and official plan directory |
| 4. Note expected care | Regular visits, therapies, equipment, and planned procedures | Care plan and provider discussions |
| 5. Compare total yearly cost | Premium, deductible, copays, coinsurance, and drug costs | Official 2027 plan documents and Medicare.gov |
| 6. Record deadlines | October 15 opening and December 7 closing | Medicare.gov and calendar |
How should you check prescriptions?
Write every medication exactly as prescribed, including dose, form, frequency, and preferred pharmacy. Then check each official 2027 formulary once available. Look for tier placement, prior authorization, quantity limits, step therapy, and pharmacy network rules. A familiar plan name does not guarantee the same drug coverage next year.
Ask the prescribing clinician about alternatives only if a coverage issue appears. Do not change a medication based on insurance information alone. Confirm clinical decisions with the clinician and coverage details with the plan.
How should you confirm doctors and hospitals?
Make a list of every provider and facility you want to keep. Search the official 2027 directory when it becomes available, then call the provider office and plan if the answer is unclear. Networks can change, and a medical group may participate differently from an individual clinician.
Check primary care, specialists, hospitals, laboratories, therapy providers, and medical equipment suppliers. For Medicare Advantage, note referral and prior authorization rules. Keep a record of whom you contacted and when.
Why compare total yearly cost instead of premium alone?
The premium is only one part of the cost. Add expected deductibles, copays, coinsurance, drug costs, and out-of-network exposure where relevant. Consider the plan's annual out-of-pocket maximum for covered services. A low premium can still produce higher total spending for someone who uses regular care.
Use your actual prescriptions and expected services, not a generic example. Do not invent or estimate unavailable 2027 figures. Compare the official 2027 plans once they appear and verify the details before enrolling.
What if your current plan or carrier changes for 2027?
Read every notice from the plan. A carrier may change benefits, networks, or service areas, or a plan may end. The notice should explain the change and available rights. Do not assume automatic enrollment will preserve the same coverage. Confirm your status before December 7.
If a change creates a special right or different deadline, use the official notice and Medicare guidance. A licensed broker can help interpret the documents, but the written plan and Medicare materials control.
What happens after December 7?
Changes made during Annual Enrollment generally begin January 1, 2027. Review the confirmation and new identification card. If you are enrolled in Medicare Advantage and the choice does not fit, the Medicare Advantage Open Enrollment Period runs January 1 through March 31 and may provide a limited fallback.
That later window does not offer every Annual Enrollment choice. Read our guide to the Medicare Advantage Open Enrollment Period in Colorado. Prepare carefully now rather than planning to fix a rushed decision later.
What are common questions about the 2027 Medicare checklist?
People preparing for Annual Enrollment often ask when documents arrive, how to verify doctors, and whether premium alone is enough for comparison. Use official 2027 plan materials once available, keep a written list of prescriptions and providers, and confirm important details with the plan, Medicare.gov, or a licensed broker.
When is Medicare Annual Enrollment for 2027 coverage?
The window runs October 15 through December 7, 2026. Changes generally become effective January 1, 2027. Confirm deadlines through Medicare.gov.
When should my Annual Notice of Change arrive?
Plans send the notice by the end of September. Contact the plan if it does not arrive, and keep the document for your review.
Should I compare plans before October 15?
You can gather documents and identify needs before October 15. Compare official 2027 plans once they appear, and do not rely on estimates or incomplete previews.
Do I need a list of medication doses?
Yes. Drug name alone may not be enough because coverage can vary by dose, form, and quantity. Include your preferred pharmacy too.
How do I know whether my doctor is in network?
Check the official 2027 plan directory and confirm with the provider office. If information conflicts, contact the plan before enrolling.
Can I change my Medicare Advantage plan after January 1?
The Medicare Advantage Open Enrollment Period runs January 1 through March 31 for people already enrolled in Medicare Advantage. Its choices are more limited than Annual Enrollment.
Should I choose a plan based only on premium?
No. Compare expected total yearly cost, provider access, prescriptions, benefits, and plan rules. Confirm every important detail in official documents.
