Important: Annual Open Enrollment is different from the Initial Enrollment Period for someone turning 65 and enrolling in Medicare for the first time.
What Can Mount Prospect Seniors Change During Open Enrollment?
Medicare beneficiaries have several options depending on their current coverage.
1. Switch Medicare Advantage Plans
If you are enrolled in a Medicare Advantage Plan (Part C), you can compare other plans available in your ZIP code.
Plans may differ in monthly premiums, annual out-of-pocket limits, provider networks, prescription drug coverage, and additional benefits.
Before changing, confirm that your preferred doctors, specialists, and healthcare facilities participate in the new plan.
2. Switch From Original Medicare to Medicare Advantage
Original Medicare includes Part A (hospital insurance) and Part B (medical insurance).
Medicare Advantage Plans are offered by private insurers approved by Medicare and provide your Part A and Part B benefits through the plan, usually with a provider network and specific coverage rules.
Many Medicare Advantage Plans include prescription drug coverage and may offer additional benefits, depending on the plan.
3. Switch From Medicare Advantage to Original Medicare
You may return to Original Medicare during the annual enrollment period.
However, it is important to understand prescription coverage and supplemental insurance requirements before making this change.
You may need a separate Medicare Part D prescription drug plan.
You may also want Medicare Supplement Insurance, commonly called Medigap, to help with eligible out-of-pocket costs. Medigap acceptance is not guaranteed in every situation, so check your eligibility and underwriting requirements before leaving your current coverage.
4. Change Medicare Part D Prescription Drug Coverage
Prescription drug plans can change their covered medications, pharmacy networks, deductibles, and copayments from year to year.
Even if your prescriptions have not changed, your total annual expenses might.
Reviewing your Part D coverage can be especially important if you take several medications or use expensive brand-name prescriptions.
What Is Changing in Medicare for 2027?

Several Medicare prescription drug provisions are especially relevant when comparing 2027 coverage.
Prescription Drug Out-of-Pocket Spending Limit
For 2027, the annual out-of-pocket limit for covered Medicare Part D prescription drugs is $2,400.
This limit applies to qualifying Part D out-of-pocket spending. It is not a limit on all healthcare expenses.
Monthly plan premiums, medical care under Part A or Part B, and drugs not covered under Part D generally do not count toward this limit.
Once you reach the applicable Part D limit, you do not pay additional out-of-pocket costs for covered Part D drugs for the rest of the calendar year.
Additional Negotiated Prescription Drug Prices
Beginning January 1, 2027, Medicare-negotiated prices for an additional group of 15 Part D medications take effect.
The actual savings for an individual depend on the medication, the insurance plan, and the person's coverage circumstances.
If you take expensive prescription medications, compare your estimated annual costs for 2027 rather than choosing a plan based only on its monthly premium.
Medicare Prescription Payment Plan
Medicare also offers a payment option that allows people with Part D coverage to spread eligible out-of-pocket prescription drug costs across monthly bills during the calendar year.
This program may help beneficiaries manage cash flow when medication costs are high early in the year.
However, it does not reduce the total amount owed for prescriptions.

Does Medicare Cover Home Healthcare in Mount Prospect, Illinois?
For older adults recovering from illness, surgery, or changes in mobility, understanding home health coverage is another important part of Medicare planning.
Medicare may cover medically necessary home health services for eligible patients who are considered homebound and need qualifying part-time or intermittent skilled care.
Covered services can include:
Skilled nursing care
Physical therapy
Occupational therapy when Medicare requirements are satisfied
Speech-language pathology services
Medical social services
Certain part-time home health aide services provided alongside qualifying skilled services
Services must meet Medicare's clinical and certification requirements and be provided by a Medicare-certified home health agency.
Important: Medicare generally does not cover 24-hour home care, meal delivery, or personal care alone when no qualifying skilled services are needed.
Before selecting a Medicare Advantage Plan, ask whether the home health agency you want to use participates in the plan's network and whether referrals or prior authorizations apply.
For residents of Mount Prospect and surrounding suburbs, this can be especially important when planning care after an illness or hospitalization.
Learn more through Medicare's official Home Health Services coverage guide.
