When Is Medicare Open Enrollment in Fort Collins?
Medicare Open Enrollment, formally known as the Annual Enrollment Period, takes place every year from October 15 through December 7. During this time, Medicare beneficiaries in Fort Collins, CO can make changes to their Medicare coverage for the upcoming year. Any changes you make during this window typically become effective on January 1.
This enrollment period applies nationwide, but the specific plan options available to you depend on where you live. In Fort Collins and Larimer County, plan availability, premiums, provider networks, and drug formularies can vary significantly from year to year. Even two neighbors in different parts of Northern Colorado may see different plan lineups based on carrier service areas.
It is important not to confuse Annual Enrollment with other Medicare enrollment periods. For example, the Medicare Advantage Open Enrollment Period runs from January 1 through March 31 and allows certain changes for people already enrolled in a Medicare Advantage plan. Initial Enrollment Periods and Special Enrollment Periods also follow separate rules based on age, disability status, or qualifying life events.
Here are the key features of the Annual Enrollment Period:
- Runs October 15 through December 7 each year.
- Changes take effect January 1 of the following year.
- Applies to Medicare Advantage, Part D, and switching between Original Medicare and Advantage.
- Available to all Medicare beneficiaries currently enrolled in Medicare.
Because this window is limited to less than two months, it is wise to start reviewing your options early in the fall. Many Fort Collins residents begin evaluating plans in September when carriers release their Annual Notice of Change documents, which outline benefit and cost updates for the coming year.
Aspen Financial & Insurance Solutions helps Medicare beneficiaries in Fort Collins review these changes in a structured way. While they do not offer every plan available in the area, they provide side-by-side comparisons of available options based on your specific prescriptions, providers, and financial goals. Eligibility and plan availability vary by carrier, county, and individual circumstances.
Key 2026 Medicare Dates to Know Locally
As you prepare for 2026 coverage, understanding the full Medicare calendar can help you avoid missing important deadlines. While the Annual Enrollment Period is the most widely recognized timeframe, several other dates may apply depending on your situation in Fort Collins.
For most beneficiaries, the following dates are the most relevant for 2026:
- January 1, 2026: New coverage selected during fall 2025 begins.
- January 1 to March 31, 2026: Medicare Advantage Open Enrollment Period.
- October 15 to December 7, 2026: Annual Enrollment Period for 2027 coverage.
- Ongoing: Special Enrollment Periods for qualifying life events.
If you are turning 65 in 2026 and live in Fort Collins, your Initial Enrollment Period begins three months before your 65th birthday month and ends three months after. This seven-month window determines when you can first enroll in Medicare Part A and Part B, and whether you can avoid late enrollment penalties.
Local timing considerations also matter. For example, retirees leaving employer coverage in Northern Colorado may qualify for a Special Enrollment Period. Missing that window could result in permanent late penalties for Part B or Part D coverage.
Aspen Financial works with individuals and families in Fort Collins to clarify which enrollment window applies to their specific situation. They review:
- Whether you are aging into Medicare or already enrolled.
- If employer coverage is ending and when.
- Whether you qualify for a Special Enrollment Period.
- How your enrollment timing impacts future premiums.
Because rules can be complex and depend on personal circumstances, it is always wise to verify details through Medicare.gov, 1-800-MEDICARE, or your local SHIP office in addition to seeking personalized guidance.
How Annual Enrollment Affects Your Plan Choices
Many Fort Collins residents assume that if they are happy with their current Medicare plan, there is no need to review it. However, Medicare plans change each year. Premiums, deductibles, copays, provider networks, and drug formularies can all shift between January and December.
During Annual Enrollment, you can:
- Switch from Original Medicare to a Medicare Advantage plan.
- Leave Medicare Advantage and return to Original Medicare.
- Change from one Medicare Advantage plan to another.
- Enroll in, drop, or switch a standalone Part D prescription drug plan.
These decisions can significantly affect your out-of-pocket costs. For example, a Part D plan that covered your medications affordably in 2025 might move a drug to a higher tier in 2026. Similarly, a Medicare Advantage plan network in Larimer County might add or remove certain providers.
Aspen Financial & Insurance Solutions provides education-first guidance to help Fort Collins clients evaluate these changes. They do not offer every plan available in a given area, but they can help you compare available options based on:
- Your current prescriptions and pharmacy preferences.
- Doctors, specialists, and hospital systems you want to use.
- Monthly premium comfort level.
- Risk tolerance for out-of-pocket costs.
All Medicare Advantage, Medicare Supplement, and Part D plans are offered by private insurance carriers approved by Medicare. Benefits, provider networks, formularies, and premiums vary by county and year. Eligibility and underwriting rules may apply in certain cases, especially for Medigap outside guaranteed issue periods.
Reviewing your Annual Notice of Change document each fall is one of the most important steps you can take to stay informed. Even small premium adjustments can add up over time.
Fort Collins Options: Advantage, Medigap, Part D
Medicare beneficiaries in Fort Collins generally choose between two main coverage paths: Original Medicare paired with a Medicare Supplement and Part D plan, or an all-in-one Medicare Advantage plan. Each option has trade-offs.
Medicare Advantage plans combine Part A, Part B, and often Part D into one plan. These plans typically include additional benefits such as dental or vision, but they operate within provider networks and have annual out-of-pocket maximums.
Medicare Supplement insurance, also called Medigap, works alongside Original Medicare. It helps cover deductibles, copayments, and coinsurance. You must enroll in a separate Part D plan for prescription drug coverage if you choose Medigap.
Here is a simplified comparison:
- Medicare Advantage:
- Bundled medical and often drug coverage.
- Network-based care in most cases.
- Annual out-of-pocket maximum.
- Medicare Supplement with Part D:
- Broad provider access nationwide with Original Medicare.
- Separate standalone drug plan required.
- Typically higher monthly premiums but lower cost-sharing.
In Fort Collins and across Larimer County, plan availability depends on carrier participation and service areas. Some plans may be offered in parts of Northern Colorado but not others. Aspen Financial provides guidance and plan comparisons but does not offer every plan available. They help review your prescriptions, providers, and financial goals to identify suitable options among available carriers.
For a full list of plans in your area, visit Medicare.gov or call 1-800-MEDICARE. Your SHIP office can also provide unbiased assistance.
What Changes Each Year in Northern Colorado
Each fall, insurance carriers announce updates for the upcoming year. These changes affect Medicare beneficiaries throughout Fort Collins and neighboring communities such as Loveland, Windsor, and Greeley.
Common annual changes include:
- Monthly premium adjustments.
- Deductible and copay updates.
- Provider network modifications.
- Prescription drug formulary revisions.
- Supplemental benefit additions or reductions.
Even if you remain in the same plan, your costs or access to certain providers may change. For example, a hospital system serving Northern Colorado might renegotiate contracts with a carrier, affecting network participation.
Aspen Financial encourages annual reviews because staying proactive can help prevent surprises. Their process typically includes:
- Running an updated prescription drug analysis.
- Confirming provider participation.
- Reviewing premium and out-of-pocket projections.
- Discussing life changes such as retirement or relocation.
It is also important to remember that broader Medicare regulations can change at the federal level. Adjustments to Part D benefit structures, cost caps, or preventive service coverage can impact beneficiaries in Fort Collins just as they do nationwide.
Because Medicare is complex and dynamic, staying informed each year protects both your healthcare access and financial stability.

Frequently Asked Questions
What is the difference between Medicare Advantage and Medigap in Fort Collins, Colorado?
Medicare Advantage plans bundle hospital, medical, and often prescription drug coverage into one plan and typically use provider networks in Larimer County. Medigap works with Original Medicare to help cover deductibles and coinsurance, and you usually add a separate Part D plan. Aspen Financial helps Medicare beneficiaries in Fort Collins, Colorado compare these options based on doctors, prescriptions, and budget, while reminding clients that plan availability and costs vary by carrier and year.
When should I enroll in a Part D prescription drug plan to avoid penalties?
You should enroll in a Part D plan during your Initial Enrollment Period when you first become eligible for Medicare, unless you have other creditable drug coverage. Delaying enrollment without creditable coverage can result in a permanent late enrollment penalty. Aspen Financial works with Fort Collins residents to review whether their current coverage qualifies and to compare available Part D options, though beneficiaries should also confirm details through Medicare.gov or 1-800-MEDICARE.
How can I compare Medicare plans using my doctors and prescriptions?
The most effective way to compare plans is to create a detailed list of your prescriptions, dosages, preferred pharmacies, and healthcare providers. Aspen Financial helps individuals in Fort Collins run plan comparisons that factor in provider networks and drug formularies, recognizing that these details change annually. Because they do not offer every plan available, clients are encouraged to review the full range of options through official Medicare resources as well.
What is the out-of-pocket maximum in a Medicare Advantage plan?
Medicare Advantage plans include an annual out-of-pocket maximum for Part A and Part B services, which limits how much you pay for covered medical services during the year. This maximum varies by plan and county. Aspen Financial helps Fort Collins beneficiaries understand how these limits compare to the predictable premium structure of Medigap, ensuring clients weigh risk tolerance and financial goals when choosing coverage.
Do annuities help with retirement income planning alongside Medicare?
Annuities can provide a stream of income in retirement, which may help cover healthcare costs not paid by Medicare. Aspen Financial offers education-first guidance on annuities for clients in Northern Colorado, explaining how they work, associated fees, and suitability considerations. Availability and terms vary by carrier and state, and decisions should align with overall retirement income strategies.
How do I choose the right life insurance policy in retirement?
Choosing life insurance in retirement depends on your financial goals, debts, income replacement needs, and legacy plans. Some retirees in Fort Collins seek coverage to cover final expenses, while others use policies for wealth transfer or charitable giving. Aspen Financial provides comparisons and education on available options but encourages clients to evaluate policy guarantees, premiums, and carrier strength carefully.
Does Medicare cover long-term custodial care in Colorado?
Original Medicare generally does not cover long-term custodial care, such as extended stays in a nursing home for assistance with daily living activities. It may cover short-term skilled nursing care under specific conditions. Aspen Financial educates Fort Collins families about long-term care insurance and other planning strategies, while emphasizing that coverage options, costs, and eligibility vary widely.
Can I change my Medicare plan after Open Enrollment ends?
Outside of the October 15 to December 7 Annual Enrollment Period, changes are limited to specific situations such as the Medicare Advantage Open Enrollment Period or qualifying Special Enrollment Periods. Life events like moving or losing employer coverage may trigger eligibility. Aspen Financial helps beneficiaries in Larimer County determine whether they qualify for a change, and beneficiaries can also verify eligibility through Medicare.gov or their local SHIP office.
