Short answer: Start with the healthcare you actually use. Compare doctors, prescriptions, pharmacies, total annual costs, network rules, prior authorization, and quality—not just the premium or extra benefits.

Step 1: Confirm your deadline

Read the ending date and reason in your notice. A plan non-renewal, contract termination, move, and individual disenrollment can create different deadlines. Confirm the applicable Special Enrollment Period before shopping.

Step 2: Build a personal coverage list

• Doctors, specialists, hospitals, laboratories, and medical suppliers. • Every prescription, dosage, frequency, and preferred pharmacy. • Scheduled procedures and ongoing treatment. • Expected travel or time spent in another state. • Dental, vision, hearing, transportation, and other benefits used regularly.

Step 3: Compare the two main paths

Another Medicare Advantage plan may combine Part A, Part B, and usually Part D, with a provider network and annual out-of-pocket maximum. Original Medicare offers broad provider access but generally requires separate decisions about Part D and Medigap and has no annual Part A/Part B out-of-pocket limit by itself.

Step 4: Estimate total cost

Compare the Part B premium, any plan or Medigap premium, deductibles, drug costs, office and hospital cost sharing, maximum out-of-pocket limit, and services not covered. A $0-premium plan is not a $0-cost plan.

Step 5: Verify, do not assume

Search results and provider offices can be outdated. Check the plan’s current directory and formulary, then call the plan and provider. Record the date, representative, and reference number. Ask about the exact plan name and contract—not merely the insurer.

Step 6: Examine restrictions and quality

Review HMO versus PPO rules, referrals, prior authorization, out-of-network coverage, drug tiers, quantity limits, step therapy, pharmacy networks, and Medicare Star Ratings. Extra benefits should be evaluated only after core medical and drug needs are satisfied.
