What is Medicare Open Enrollment and when does it happen?

Medicare Open Enrollment (also called the Annual Enrollment Period or AEP) runs from October 15 through December 7 every year. During this seven-week window, all Medicare beneficiaries can switch from Original Medicare to a Medicare Advantage plan, change Medicare Advantage plans, add or drop Part D prescription coverage, or return to Original Medicare. Changes take effect January 1 of the following year.

If you miss this window, you typically must wait until next year unless you qualify for a Special Enrollment Period due to relocation, loss of other coverage, or certain life events. That makes these seven weeks critical for getting your coverage right.

Why should I review my Medicare plan every year?

Even if you liked your plan last year, insurers change coverage details annually. Your 2024 plan may have different copays, a revised formulary (drug list), altered provider networks, or changed star ratings in 2025. The average Medicare Advantage enrollee who shops around saves $621 annually compared to auto-renewers, according to a Kaiser Family Foundation analysis.

Your health needs also change. You may take new medications, need different specialists, or travel more frequently. A plan that worked when you were 66 may not fit at 72.

How do I compare Medicare plans in under 30 minutes?

Follow this streamlined process to evaluate your options efficiently:

**Step 1: Gather your current information (5 minutes)**

Collect your Medicare card, current plan ID card, a list of all prescription medications (drug name and dosage), and the names of doctors you want to keep seeing. Have your pharmacy's name handy.

**Step 2: Visit Medicare.gov Plan Finder (2 minutes)**

Go to Medicare.gov/plan-compare. Enter your ZIP code and answer basic questions about your current coverage. You do not need to create an account to browse plans.

**Step 3: Enter your prescriptions (8 minutes)**

Add each medication with dosage and frequency. The tool calculates your estimated annual drug costs for each plan, accounting for deductibles, copays, and coverage gaps. This single feature often reveals savings of $1,000+ per year.

**Step 4: Filter by your priorities (3 minutes)**

Check boxes for must-have features: your doctors in-network, your pharmacy included, dental/vision coverage if important, or a $0 premium. Sort results by lowest estimated annual cost (premium plus expected out-of-pocket).

**Step 5: Review top 3 plans side-by-side (10 minutes)**

Compare the three lowest-cost options. Check star ratings (4+ stars preferred), maximum out-of-pocket limits, and any extra benefits like gym memberships, telehealth, or over-the-counter allowances.

**Step 6: Confirm network and formulary details (2 minutes)**

Click through to verify your primary care doctor and any specialists accept the plan. Confirm your pharmacy is in-network at preferred tier.

What are the main differences between Medicare plan types?

| Plan Type | How It Works | Typical Monthly Premium | Provider Flexibility | Prescription Coverage | |-----------|--------------|------------------------|---------------------|----------------------| | **Original Medicare (Parts A & B)** | Fee-for-service government insurance | Part B: $174.70 (2024 standard) | Any provider accepting Medicare nationwide | Requires separate Part D plan | | **Medicare Advantage (Part C)** | Private insurance replacing A & B | $0–$200+ (average $18) | Network-based (HMO, PPO) | Usually included; verify formulary | | **Medigap (Supplement)** | Works with Original Medicare to cover gaps | $50–$400+ by plan letter | Use with Original Medicare's flexibility | Requires separate Part D plan | | **Part D Stand-Alone** | Prescription-only add-on for Original Medicare | $0–$100+ (average $40) | N/A (pairs with Original or Medigap) | Only drug coverage |

What key factors should I prioritize when comparing plans?

**Total annual cost matters more than monthly premium.** A $0 premium Medicare Advantage plan may cost $3,000 yearly after copays, while a $40/month plan with better coverage totals $2,100. Always calculate premium times 12, plus expected out-of-pocket maximums and drug costs.

**Star ratings indicate quality.** Medicare rates plans 1-5 stars based on customer service, care quality, and member satisfaction. Plans with 4+ stars typically offer better experiences and sometimes extra benefits. A 2-star plan with great pricing may frustrate you with poor service.

**Formulary tiers determine drug costs.** Your medication's tier (1-5) drastically affects copays. The same drug might cost $10/month as tier 1 on one plan, $150/month as tier 4 on another. Always enter your exact medications into the comparison tool.

**Network size affects access.** HMO plans offer lower premiums but restrict you to network providers and require referrals. PPO plans cost more but allow out-of-network care at higher copays. Local PPOs work well if you winter in another state.

**Maximum out-of-pocket (MOOP) caps your risk.** This is the most you will pay for covered services annually (excluding premiums). In 2024, Medicare Advantage MOOP limits cannot exceed $8,850 for in-network care. Lower MOOP means better financial protection if you face serious illness.

How do prescription drug costs vary between plans?

The same medications can cost vastly different amounts depending on your Part D plan or Medicare Advantage drug coverage. A real example from Cleveland, Ohio in 2024: atorvastatin 40mg (generic cholesterol drug) ranged from $0 to $47 monthly across available plans for the same person.

Medicare Part D has four coverage phases: deductible period (you pay full cost until meeting deductible), initial coverage (you pay copays/coinsurance), coverage gap (you pay 25% for brands, generics), and catastrophic coverage (you pay 5% above $8,000 spent). Plans structure these phases differently.

Always use the Plan Finder's drug cost calculator rather than guessing. It accounts for your specific medications, dosages, pharmacy choice, and mail-order options to show true annual costs.

What are common mistakes people make during Open Enrollment?

**Auto-renewing without reviewing.** Your plan likely changed its formulary, network, or costs for the new year. Spending 30 minutes comparing could save you thousands.

**Focusing only on premium.** A $0 premium plan with high copays and a $6,700 MOOP may cost far more than a $50/month plan with a $3,000 MOOP if you need care.

**Ignoring star ratings.** Low-rated plans often have poor customer service, claim-processing delays, and frustrated members. These headaches compound when you are dealing with health issues.

**Not checking if doctors are in-network.** Networks change yearly. Your cardiologist may have accepted your plan in 2024 but dropped it for 2025. Always verify.

**Forgetting about travel needs.** If you spend winters in Arizona but live in Michigan, a Michigan-only HMO leaves you with limited emergency-only coverage down south. Consider a PPO or Original Medicare with supplement.

**Skipping the Extra Help program.** If you earn under $23,000 (individual) or $31,000 (couple), you likely qualify for Extra Help that covers most Part D costs. Apply at ssa.gov/benefits/medicare.

When should I get professional help comparing plans?

Consider consulting a licensed Medicare advisor (State Health Insurance Assistance Program counselor or independent broker) if you take five or more medications, have complex conditions requiring specialists, feel overwhelmed by options, or want someone to handle enrollment paperwork. These services are free through SHIP programs (find yours at shiphelp.org) or commission-based through brokers (no cost to you).

If you prefer independent research but want to ensure you have not missed anything, schedule a 15-minute call with a licensed agent after doing your initial comparison. They can spot formulary issues or network gaps you may have overlooked.
